Kingtone Bluebird J1 Pickups — Jesse Davey
The best Stratocaster pickups I've ever played — and a full demo of the KingTone ecosystem in one video. Welcome back to Edge of Breakup.
In this episode the KingTone Blue Bird J1 Pickups take center stage in the Nash S63, alongside the KingTone SRV Switch installed in the secondary tone position and a dedicated mini pedalboard of KingTone pedals — Vintage Fuzz, Vibe 1968, and The Duellist v1 — all into the Benson Amps Monarch.
KingTone Guitar is the work of Jesse Davey out of Canada. Jesse has devoted his career to designing the ultimate vintage Stratocaster pickup and the boutique pedals that complement it. The BlueBird J1s were designed in 2006 and have maintained precise, exacting specifications throughout production — meticulously designed to get as close to the Stevie Ray Vaughan tone as possible.
Specs: Neck 5.8k / Middle 5.7k / Bridge 5.6k. Staggered Alnico V magnets. Vintage spec Heavy Formvar 42 AWG wire. Scatter wound on custom winding machines. Hand-bevelled pole pieces. The bridge pickup is voiced specifically to deliver full, playable tone without the harshness associated with overwound pickups — bright without ice-pick, extended in the low end without mud.
The Vintage Fuzz features four transistors — both AC128 and NKT275 Germanium transistors accessible via two switches, selectable and mix-and-matchable across the two gain stages. AC128 for smooth, softer fuzz with lower gain; NKT275 for brighter, more aggressive fuzz. External bias adjustment. Battery simulator for DC power supply.
The Vibe 1968 is a dual-channel Uni-Vibe with independent Rate and Depth on each side, switchable between Chorus and Vibrato modes, with an A/B channel footswitch.
The Duellist v1 is Jesse's two-channel overdrive — one side is String Singer (Dumble-voiced), the other is Heavy Hand (Bluesbreaker-voiced) — explored here both independently and stacked.
The KingTone SRV Switch replaces the secondary tone control and provides six additional tonal positions for treble bleed and filter configurations voiced specifically for the BlueBird J1 pickups.

Ground Control Audio Bread Oath Overdrive
The hits keep coming in 2023. Ground Control Audio's Bread Oath is a thoughtfully evolved overdrive that earns its place on the board immediately. Welcome back to Edge of Breakup.
In this episode the Ground Control Audio Bread Oath Overdrive takes center stage — featuring the Frank Brothers Signature with Lollar '50s Wind P90 and Lollar Low Wind Imperial Humbucker, into the Benson Amps Monarch.
Built around the foundation of Ground Control's very first pedal — 2016's Blood Oath — the Bread Oath retains the character that made the original unique while offering revised filters, tighter tonal response, and over six years of user feedback incorporated into the design. Ground Control is a Montreal boutique builder — the Bread Oath is the evolution of company owner Sébastien Vézina's original signature circuit.
An opamp-based, low-to-mid gain overdrive designed to push an amp into breakup and add flexible flavors of diode clipping. Four controls: Volume (output), Gain (main clipping stage), Tone (rolls off highs entering the clipping stage), and Pre (controls the secondary preamp stage gain).
The key feature is the dual clipping architecture. A top-mounted toggle selects between silicon diodes (tighter, more modern, more compressed character) and germanium diodes (more open, rawer, vintage character). These aren't radical differences — they're the subtle textural shift that makes a real difference in context, particularly with the Frank Brothers Signature's ability to blend a P90 and a humbucker simultaneously.
A separate pre-gain stage can be engaged via the left footswitch. This stage sits before the clipping diodes, driving them harder for additional bite and saturation. A low-pass filter between the two gain stages shaves high-end harmonics from the pre-gain stage to avoid harsh distortion. The Pre level is set independently with its own knob — dial it in for just a touch of extra cut during leads, or max it for significantly more gain and presence.
Built in Canada. True bypass. 9V DC center negative, no battery.

Thorpy FX Boneyard Fuzz
Has ThorpyFX created the perfect Tone Bender? After spending time with this pedal, I think Adrian Thorpe might have. Welcome back to Edge of Breakup.
In this episode the ThorpyFX Boneyard Fuzz takes center stage — featuring the Frank Brothers Arcade with Lollar '50s Wind P90s, into the Benson Amps Vincent and Benson 2x12" cabinet.
The Boneyard packs tones from classic Tone Bender circuits MK I through MK IV into one stompbox using three germanium transistors. Adrian Thorpe of ThorpyFX describes it as a vanity project — his interpretation of what the ultimate Tone Bender would sound like after years spent playing, testing, and obsessing over every era of the circuit. Limited to approximately 250 units due to the scarcity of suitable germanium transistors — only a very narrow band is appropriate for the circuit, and finding enough took years.
Four controls, all extremely interactive in the manner of a Zvex Fuzz Factory — micro-adjustments at the intersection of all four knobs unlock sweet spots unavailable at any single setting.
Level controls output volume. Attack is the fuzz gain control — from lighter fuzz through to searing sustain. Tone controls treble and bass response — counterclockwise for smoother sounds, clockwise for brighter. Feed acts as a master bias control, adjusting the voltage to the pedal — choke it for sputtering, gated fuzz, or open it up for a smoother, more polished character.
The left footswitch bypasses the Tone stack entirely — removing the treble shaping from the circuit for a different tonal response and greater overall output. The central toggle switches between three-transistor mode (MK II through MK IV voicings — the classic saturated bender character) and two-transistor mode (MK I and MK I.V — closer to a Fuzz Face character, drier, more direct). 1% metalfilm resistors, Wima and Panasonic capacitors, Neutrik jacks, gold-plated PCB with dust-sealed potentiometers throughout.

Greer Amps Black Mountain Crunch Drive
Brand new from Greer Amps — and it's one of the most natural, amp-like crunch drives I've played. Welcome back to Edge of Breakup.
In this episode the Greer Amps Black Mountain Crunch Drive takes center stage — stacked with the Greer Moonshot Treble Booster for the second half of the demo — featuring the Frank Brothers Ultralight with Lollar El Rayo Humbuckers and Lollar Firebird on a Blender Pot, into the Benson Amps Monarch and Benson 2x12" Celestion G12H cabinet via the Boss Waza Tube Amp Expander.
Nick Greer of Greer Amps built the Black Mountain around a specific tone quest — the sound of one particular modded Marshall amp he encountered visiting a close friend, from the post-Plexi era metal panel period that came just after the great Plexiglass-panel amps of the late '60s. From simply adding crunch to getting that famous midrange snarl and growl of those metal panel amps, the Black Mountain gives up the goods in a way that has a natural, amp-like crunch to it. The whole thing was developed with The Darkness' Permission to Land blasting in the background — prime British crunch territory.
The two clipping diodes responsible for the drive in this circuit are purposefully imbalanced, selected to impart the proper texture and crunch. This intentional mismatch is what gives the Black Mountain its characteristic asymmetric bite — crisping up even at relatively low gain settings in a way that symmetrical clipping simply cannot produce.
Three knobs: Volume, Gain, Tone. Can be powered from 9V to 18V for additional headroom. The pedal is used here in two very different contexts: into a breaking-up Monarch (where the Black Mountain adds texture and character on top of amp-derived distortion), and as the sole gain source into a clean amp (where it drives every note of the distortion on its own).
The Greer Moonshot Treble Booster enters later in the demo, pushing the Black Mountain's input from the front for additional gain, midrange emphasis, and focus.

Cunningham Amps ZONK MKI Fuzz — Strat Tones — Lost in Crystal Canyons
Three demos, three completely different guitars. The ZONK | MKI sounds different every time. Welcome back to Edge of Breakup.
This is the third Lost in Crystal Canyons x Cunningham Amps ZONK | MKI demo on the channel — this time with the Nash S63 Stratocaster into the Benson Amps Vincent with Boss Waza Tube Amp Expander for reverb.
Previous demos:
With Frank Brothers Arcade / P90s: https://youtu.be/4QP_uT-XDXU
With 1967 Gibson ES-335 / Humbuckers: https://youtu.be/w_CSIo9B5i8
The short version of the pedal: two fully independent NOS germanium circuits — a Zonk Machine (left toggle) and a Tone Bender MKI (right toggle) — in a solid steel enclosure with NOS knobs and a battery kill switch. Two knobs: Fuzz (left, gain) and Level (right, output). Single-digit production drops. Built by Tim Cunningham in Auckland, New Zealand. Designed by Robert Hart of Lost in Crystal Canyons.
What the Nash S63 single coils bring to this pairing that the P90s and humbuckers don't: a tighter, clearer initial transient that makes the NOS germanium transistors' response feel more immediate and touch-sensitive. The Fuzz knob has more usable range across the full sweep. The guitar volume cleanup — particularly in the neck/middle position — is extraordinarily linear and musical. The Benson Vincent's clean headroom keeps everything open and three-dimensional in a way that rewards the single coil's frequency response.
The comparison between the Tone Bender MKI and Zonk Machine circuits is explored in detail in this demo — both at full crank, both cleaned up, and both with the level inverted as a volume control while the gain acts as the character adjuster.

Walrus Audio Melee | Instant Shoegaze Pedal
Two weeks into 2023 and I've already found my favorite pedal of the year. The Walrus Audio Melee: Wall of Noise is exactly what it says it is. Welcome back to Edge of Breakup.
In this episode the Walrus Audio Melee takes center stage — featuring the Baum Guitars Wingman into the Benson Amps Monarch and Benson 2x12" cabinet with Celestion G12H speakers via the Boss Waza Tube Amp Expander.
The Melee gives you two of the most powerful effects in guitar — high-gain distortion and reverb — and lets you decide not just how much of each, but in what order they hit each other, and in real time. That's the whole concept.
The joystick is the primary control. Moving it up increases distortion intensity. Moving it left-to-right adjusts the reverb wet/dry mix. Every position between center and the four cardinal points is a unique combination of gain and space — from almost dry and barely distorted, to fully dimed distortion with a completely wet reverb signal. Slam it all the way right and the dry signal disappears into pure ambient wash with distortion running through it. It plays like a video game and sounds like shoegaze.
A toggle switch controls the signal order: Distortion into Reverb (traditional — lush, singing leads with reverb trailing the distortion) or Reverb into Distortion (experimental — the reverb trail itself gets saturated, creating an impenetrable wall of processed atmospheric noise). Three reverb programs: Ambient (lush trails, soaring sustain), Octave Down (low-octave doubling in the reverb trail — similar to the Slö's Dark mode), and Reverse Reverb with Feedback (reversed trails that accumulate and cascade on themselves). Three-position Tone toggle (Dark/Medium/Bright) and three-position Decay toggle. Modulation added via the bypass + decay toggle combination.
The Sustain footswitch is the performance secret — momentary hold ramps up reverb trails, release tapers them off. Latch it for sustained pad underneath continued playing.

Lollar Pickups Standard Wind P90s
The Frank Brothers Arcade Goldtop is getting a pickup upgrade — and this time, more heft. Welcome back to Edge of Breakup.
In this episode the Lollar Standard Wind P90 Soapbar pickups take center stage in a dedicated guitar pickup demo — installed in the Frank Brothers Arcade Goldtop, into the Benson Amps Monarch at three different gain levels: clean (around 3), broken up (around 6), and cranked.
The Frank Brothers Arcade originally came with Lollar '50s Wind P90s installed by Frank Brothers as part of the build. The '50s Wind is a specific voicing — based on copies of Sean Costello's '53 Goldtop, with de-gaussed Alnico 2 magnets producing lower output, a delicate attack, and a brighter, more balanced frequency response. It's an excellent pickup for clean clarity and chime.
The Standard Wind P90 uses Alnico 5 magnets and is more midrange-forward, with more of the characteristic growl that players tend to associate with P-90s. More wind means more output, warmer attack, and more immediate saturation when you push an amp. For a maple-top / mahogany-body guitar into a Benson Monarch — where the maple is already contributing brightness and articulation — the Standard Wind's added midrange warmth and heft is the better pairing. The tone knob capacitor interaction in the middle position holds some especially good sounds in this configuration.
This is a direct A/B in the same guitar, same amp — the sonic difference between Alnico 2 lighter output and Alnico 5 midrange heft, in a guitar and amp combination that shows both clearly.

Fish Circuits Model One | Strat Tones!
The long-awaited Strat demo for the Fish Circuits Model One — and the goal is simple: slam the front end of the Benson Monarch on the edge and push it over completely. Welcome back to Edge of Breakup.

🔊 Benson Amps: https://www.bensonamps.com/guitar-amplifiers
The Model One is a natural, amp-like overdrive with three controls and two switches. At lower gain settings it delivers dynamic, amp-like breakup that reacts to your playing. Cranked, it gets into saturated fuzzstortion territory reminiscent of orange amplifiers.
This demo covers the full sweep of the pedal's flexibility across two very different roles: clean amp enhancement and pushed-amp interaction.
N mode is the story when the amp is clean. More volume output, less gain, high headroom — the closest thing to a pure amp-front-end slam the Model One offers. With Level pushed past unity and Drive pulled back, it hits the Monarch's input stage hard with level, EQ, and topology rather than with clipping. The Monarch responds by contributing all the saturation. The Body switch's low-frequency control becomes the key variable — backing off the lows gives the Monarch's preamp room to bloom; pushing them adds mass and sustain.
B mode takes over when the amp is already breaking up. More gain, more compression, clipping diodes engaged — the Model One becomes part of the dirt rather than a pure amp driver. The interaction between B mode and a pushed Benson is where the "fuzzstortion" character lives.
The Giordano Guitars '60s S-Model's single coils reveal a different side of the Model One than the El Rayo humbuckers in the first demo — more immediate transient response, more Top End knob range in play, and the neck/middle pickup position quack behaving particularly well with medium Body settings.

Total Gravy Guitarworks is built around one mission: recreate the vintage pickup tones that made players fall in love with the guitar. Every pickup handmade to order in Fullerton, CA using period-correct materials and NOS coil wire. The Early PAF targets the original 1957-1959 Patent Applied For humbucker character — Seth Lover's original design, scatter-wound, pre-wax-potted, with the open top-end and complex harmonic response that defines the real vintage PAF sound. In this demo the focus is on the pickup's full tonal range: clean brightness and articulation at lower amp volumes, then the bloom and sag at cranked Monarch levels. Both ends of that spectrum matter.
The Gibson SG Standard '61 Reissue has been substantially modified. StewMac Locking Kluson tuners and StewMac bone nut resolved the original tuning stability issues. Emerson Custom SG Wiring Kit throughout, with Emerson Custom Treble Bleed on both volume knobs. TonePros ABR-1 replacement saddle with nylon saddles.

My 2023 Pedalboard — feat. Baum Guitars Wingman
A year's worth of pedal demos, condensed into one board. Welcome back to Edge of Breakup.
This is the first 2023 pedalboard — a medium-sized build using a selection of the best pedals that came through the channel in 2022. Seven pedals. The Baum Guitars Wingman. Into the Benson Amps Monarch. Here's what's on it and why.
Lost in Crystal Canyons x Cunningham Amps Zonk | MKI — two fully independent NOS germanium circuits in one solid steel enclosure: a Zonk Machine (left toggle) and a Tone Bender MKI (right toggle). Single-digit production drops. The fuzz on this board.
Fish Circuits Model One — natural amp-like overdrive. N mode: open, high-headroom, treble booster character. B mode: compressed, clipping-diode engaged, almost fuzz-like at max gain. Body switch controls low-frequency content at the input. The always-on tone shaper.
Horrothia Effects Berkeley Uni-Vibe — four hand-matched Vactrols, NOS 2SC828 transistors, Mylar caps, carbon comp resistors. Three internal trimpots for deep voicing. Expression input. The modulation voice.
Cornerstone Imperivm — Gladio SC (Dumble) on the right, Antique (TS808) on the left, each with their own footswitch and a stacking Order switch. The dual-channel overdrive heart of the board.
Browne Amplification Carbon — the "Blue" channel of the Protein Dual Overdrive. Bluesbreaker-inspired, JFET circuit, three knobs, enormous range. The amp enhancer.
Walrus Audio Eons Five-State Fuzz — five fuzz voices (silicon, germanium, LED) and a voltage knob from 3V to 18V. The chaos option.
Meris LVX — modular delay system. 2540ms of dual delay, processing elements including Polymoon, Hedra, Enzo, and Ottobit Jr., all placeable in four positions in the signal path. The stereo ambient dimension.

Baum Guitars Wingman feat. 29 Pedals EUNA & OAMP
Dream guitar day. The Baum Guitars Wingman arrived the same day as the 29 Pedals EUNA and OAMP — and the pairing was immediately extraordinary. Welcome back to Edge of Breakup.
In this episode the Baum Guitars Wingman, 29 Pedals EUNA, and 29 Pedals OAMP take center stage together — into the Benson Amps Monarch and Benson 2x12" cabinet via the Boss Waza Tube Amp Expander.
The Baum Wingman is a modern offset solid body from Aarhus, Denmark — winner of the Gold Award at the London Design Awards for a design that is immediately identifiable without borrowing from anything already on the market. Mahogany body at 36mm — thinner than most offset builders use, which on this body shape does specific work in weight and resonance. Roasted maple neck with satin finish. Goldsound Jabmaster single coil pickups — in-house engineered and custom-wound since 2016, delivering clear highs, warm mids, and plenty of punch. Bigsby vibrato. Baum ships every guitar direct from Denmark with a 45-day home trial.
The 29 Pedals EUNA (Elite UNity Amplifier) lives at the front of the chain. An input driver designed to replace conventional buffers, EUNA protects and conditions the instrument signal with three sweetening circuits — Harmonics (tube-like chime in the air band), Bright (high-end enhancement), and Low (subtle low-end restoration). Its effects loop activates when EUNA is OFF — designed for use with vintage or vintage-style fuzz pedals sensitive to buffering. WHATEVER power supply accepts 7.5–35V AC or DC in either polarity.
The 29 Pedals OAMP (Output AMPlifier) lives at the end of the chain. Up to 29dB of clean output gain via two toggleable gain stages with a Level control between them. A Presence knob adds or subtracts sparkle. The alt path insert loop is active when OAMP is OFF for pedalboard channel-switching. Handbuilt in California with 1% thin-film resistors, WIMA film capacitors, and audiophile-grade components throughout.
Together — EUNA first in chain, OAMP last — the improvement in feel, snap, and harmonic richness is immediate and significant.

Boss RE-202 Space Echo
The full-featured Space Echo experience — the RE-202 is the one you get when you want every knob on the surface and the ability to store what you dial in. Welcome back to Edge of Breakup.
In this episode the Boss RE-202 Space Echo takes center stage. After two RE-2 demos (preamp on: https://youtu.be/DYWpMujA_U8 | preamp off: https://youtu.be/8IapAovWg7o) — this is the RE-202. Guitar is the Frank Brothers Ultralight with Lollar El Rayo Humbuckers at neck and bridge, Lollar Firebird in the middle on a Blender Pot, and a Bigsby trem, into the Benson Amps Monarch and Benson 2x12" cabinet via the Boss Waza Tube Amp Expander.
The RE-202 and RE-2 share the same core RE-201 circuit reproduction — the same JFET preamp, mixer stage, and high-gain silicon transistor record and playback amplifiers. The differences between them define the upgrade:
A fourth virtual tape head expands the available echo combinations from 11 to 12, covering head configurations impossible to achieve with a real RE-201. A dedicated Saturation knob replaces the RE-2's preamp on/off toggle — adding magnetic tape compression and preamp coloration continuously, from clean through warm to grimy overdrive on the repeats. Bass and Treble knobs shape the EQ of the echo signal independently. A Reverb Type selector expands beyond spring reverb to include hall, plate, room, and ambience. A button flips between 'new' and 'aged' virtual tape. Four onboard presets — expandable to 127 via MIDI — with a dedicated Memory footswitch. Three footswitches total (vs one on the RE-2), with Warp and Twist available on dedicated switches.
The Saturation knob is the key creative addition. At zero you have the RE-2's "preamp off" transparency — clean, analog dry-through. Sweep it up and the repeats accumulate compression and magnetic tape character. At maximum you're pushing the RE-201's preamp circuit hard enough to have the repeats saturating and crashing into each other. That range — from clean to filthy — is unavailable on the RE-2 without switching modes entirely.

Jackson Audio Optimist | Cory Wong Signature Dual Overdrive
Four sounds from one pedal — two overdrive channels, a stacked mode, and a three-band EQ that doubles as a standalone tool. The Jackson Audio Optimist is the most versatile overdrive in this class. Welcome back to Edge of Breakup.
In this episode the Jackson Audio Optimist takes center stage — Cory Wong's (Vulfpeck / Fearless Flyers) signature dual overdrive — running into my Nash T63 Telecaster with Lollar Pickups and Emerson wiring, into the Benson Amps Monarch and Benson 2x12" cabinet via the Boss Waza Tube Amp Expander with Benson Tall Bird for tube reverb.
The Optimist was designed by Brad Jackson and Cory Wong around a simple idea: take the two most celebrated transparent overdrive circuits in history, put them in one box, and add a studio-grade EQ section. The result covers four distinct voices.
OD1 is the Klon Centaur circuit, reproduced in exact detail with germanium diodes for the characteristic mid hump and compressed, sweet overdrive character the original is famous for. This is the circuit that has inspired more boutique overdrives than any other, and Jackson Audio's reproduction is meticulous.
OD2 is the Timmy-style circuit — designed to be perfectly flat across the full range of the guitar, intended for rhythm work and as a complementary harmonic enhancer for OD1 when stacked. The EQ curve of OD2 deliberately contrasts OD1's mid hump — together they balance each other while adding cumulative gain and harmonic richness. When the two pair together they create an even more boosted drive that doesn't squeal, because they're both mid-level drives.
The three-band Baxandall-inspired EQ — activated by pressing both footswitches simultaneously — is post-OD and fully bypassable. ±12dB of boost or cut per band, with center detents for easy return to flat. Used as a boost, it pushes your guitar signal into your amp's sweet spot. Used as a cut, it surgically removes the frequencies that mud up a guitar in a live or recorded mix. As a standalone EQ with both ODs bypassed, it shapes your clean tone.
Four sounds: OD1 alone, OD2 alone, both stacked, and the EQ engaged — any combination via MIDI or footswitch. This demo explores all of them.

Cornerstone Imperivm Dual Overdrive
The most legendary tonal combination in boutique overdrive — Dumble meets Tube Screamer — in one compact Italian-built pedal. Welcome back to Edge of Breakup.
In this episode the Cornerstone Imperivm takes center stage — the new successor to the beloved Gladio Double Preamp — running into the Giordano Guitars '60s S-Model, into the Benson Amps Monarch.
Cornerstone Music Gear is a family-owned operation run by husband and wife Emilio and Linda Massari in Italy. Emilio has a background in aerospace engineering — that precision carries through to every circuit. The Imperivm combines two Cornerstone pedals into one box: the Gladio SC (Dumble-inspired) on the right and the Antique (Tube Screamer-inspired) on the left, each with their own footswitch, and an Order switch that routes them in either direction.
The Gladio side is built around Emilio's interpretation of the Alexander Dumble amplifier circuit — the most sought-after and least-attainable amp sound in existence, associated with Robben Ford, SRV, and Eric Johnson. The Clean knob blends the dry signal with the overdriven tone, giving precise control over dynamics and clarity for a touch-sensitive overdrive that feels like a true extension of your fingers. A Comp switch adjusts compression character. Controls: Gain, Tone, Volume, Clean, Comp.
The Antique side is Cornerstone's refined take on the TS808 Tube Screamer, targeting the vocal, singing mid-forward drive of John Mayer's clean-to-crunch tone. The Presence knob shapes high frequencies after clipping — dial in extra edge and clarity to cut through the mix, or roll back for warmer vintage tones. A Mids switch toggles between the classic TS808 mid-hump and a cut setting for a more neutral voice. Controls: Gain, Tone, Presence, Volume, Mids, Comp.
Stack them in either order — Antique into Gladio (TS character driving the Dumble) or Gladio into Antique — and the stacking behavior is dramatically different depending on direction. The combination of mid-push from the Antique into the Gladio's compressed, harmonically rich voicing is the main event of this demo.

Cunningham Amps Dual Range Fuzz (NOS Telefunken BC108 Silicon Transistors)
A hand-wired Tone Bender with a built-in footswitchable boost — built one at a time in New Zealand by Tim Cunningham. Welcome back to Edge of Breakup.
In this episode the Cunningham Amps Dual Range Fuzz takes center stage — running into my Nash S63 Stratocaster with Lollar Pickups and Emerson Treble Bleed, into the Benson Amps Monarch and Benson 2x12" cabinet via the Boss Waza Tube Amp Expander with the Benson Tall Bird for tube reverb.
The Dual Range Fuzz is based on Cunningham's MK 1.6 circuit and takes it further by adding an additional boosted fuzz mode that can be fine-tuned for extra gain and volume. Available in Germanium, Silicon, or a Hybrid model featuring one of each transistor — all high-quality NOS devices, hand-selected and tested in each individual circuit.
The circuit is built on a hand-etched board with the highest quality components and obsessive attention to detail. Each pedal is built by hand, one at a time, and individually voiced to optimize its specially selected pair of transistors — no two pedals are exactly the same.
Four controls across two footswitches. The fuzz side: Attack (fuzz gain) and Level (output, from subtle to sonic destruction). The boost side: its own Gain and Volume knobs, footswitchable independently — set the pedal up for two quite distinct tones, or add just a touch of extra grunt to your rhythm tone for lead work. There's also a Boost Low Cut switch which shaves off bottom end when in Boost mode and Gain is fully cranked — up position gives full range fuzz, down position reduces bass response for extra cut in the mix.
Raising the Level hits the input of your amp harder and interacts with tube preamp stages to produce beautiful overtones and a wide range of overdrive and distortion tones through to raging fuzz. The guitar volume knob cleanup — especially with the stacked boost and fuzz both active — is the discovery moment of this demo.

Lollar Pickups ‘50s Wind P90s
A dedicated demo for the guitar that started everything on this channel. The Frank Brothers Arcade is the finest solidbody electric guitar I've played. Welcome back to Edge of Breakup.
In this episode the Frank Brothers Arcade Model takes center stage — with Lollar '50s Wind P90 Soapbar pickups, through the Benson Amps Monarch at varying gain levels from clean to pushed.
Frank Brothers Guitar Company was founded in Toronto by twin brothers Tim and Nick Frank alongside their brother Jon. Tim and Nick run the bench — lifelong builders with an obsession with quality that runs through the family. Players including Trey Anastasio, Clay Cook of the Zac Brown Band, and David Ryan Harris (who tours and records with John Mayer) have made Frank Brothers guitars part of their working rigs.
The Arcade is Frank Brothers' signature model — a double-arched solid body noted for its eye-catching look, comfortable playability, and warmth, sustain, and openness. The construction details that make it distinctive: a carved top and back, extra-deep neck tenon, blended heel, and 25" scale with a 12" radius fretboard. Set-neck construction. The combination of maple top over genuine mahogany body and neck gives the Arcade a voice that sits between a Les Paul and something much more open — the maple brings the articulation and brightness, the mahogany brings the warmth and sustain, and the architecture lets both breathe.
This specific build: Goldtop finish. Maple top / mahogany core and neck. Macassar ebony fretboard with split parallelogram Italian pearloid inlays. Piano black headstock. Solid bone binding throughout — top, fretboard, and headstock. Bone nut. Jescar 51108 frets. Classic Medium C neck shape (0.860"–0.940"). B5 Bigsby. Kluson Deluxe nickel tuners. Gold bell knobs. Cream bone pickguard with clear acrylic cavity cover. Lollar '50s Wind P90 Soapbars at neck and bridge. Single volume (with Emerson Treble Bleed) and single tone, 3-way toggle. The tone cap holds some genuinely great sounds in the middle position — explored in this demo.

R2R Electric Supa MKII Fuzz
The best fuzz I've ever played. Every knob is usable across its full span. Welcome back to Edge of Breakup.
In this episode the R2R Electric Supa MKII Fuzz takes center stage — running into my Giordano Guitars '60s S-Model, into the Benson Amps Monarch (NOS Tung Sol tubes) through the Boss Waza Tube Amp Expander with the Benson Tall Bird in the effects loop, into the Benson Vincent 2x12" cabinet.
The Supa MKII is Chris Vincent's (@djlavalamp) synthesis of two circuits that are essentially the same pedal under different names: the Sola Sound Tone Bender MKII and the Marshall Supa Fuzz — both made by the same people in the mid-1960s, the Supa Fuzz being a slightly evolved version of the MKII produced for Marshall's retail catalog. Chris combined his favorite elements of both and made modifications of his own, resulting in more overall volume headroom and a wider sonic palette while maintaining the integrity of the original circuit.
The components are what define a R2R build. Three hand-selected and matched vintage 1960s Amperex 2N280 and Mullard OC75 germanium transistors. Vintage Stackpole, CTS, and Centralab potentiometers. 1960s Philips Mustard Cap capacitors. 1960s ERO Foil capacitors. NOS Philips 10uf and 47uf capacitors. NOS Piher and Philips resistors. Every component recycled from 1950s and 1960s audio gear. Hand-wired.
The three-knob version featured here adds an external Bias control to the Volume and Fuzz — the Bias knob is where the range of this pedal truly opens up. Dial it into the sweet spot for the classic Tone Bender MKII / Supa Fuzz bloom and sustain. Push it hot for compressed, thick fuzz. Back it off for gated, spitty, broken territory. The circuit is extremely reactive to your guitar volume control — you can get tones ranging from crystal clean to bright overdrive to massive fuzz, all from rolling back the volume knob.

Origin Effects Halcyon
The Tube Screamer is one of the most cloned circuits in history. The Origin Effects Halcyon is the one that actually fixes it. Welcome back to Edge of Breakup.
In this episode the Origin Effects Halcyon Green Overdrive takes center stage — into a clean Benson Monarch and then pushing a breaking-up amp, covering both primary use cases thoroughly. Origin Effects is best known for their Cali76 compressor series — their precision approach to engineering applies here in full.
The Tube Screamer's most persistent problem has always been its "all or nothing" nature. At full guitar volume you get the famous mid-pushed drive. Roll back the guitar volume and the tone goes dull and lifeless — the mid hump and low-end cut that define the TS sound don't shift as you clean up, they just collapse. The Halcyon's Adaptive circuit is the fix.
The Adapt toggle has three positions. Off is pure TS808 behavior. Position I is intermediate adaptive shift. Position II is full adaptive frequency profile shifting — as you roll back your guitar's volume, the pedal's treble and bass roll-off reduce progressively, revealing the full frequency profile of your clean tone rather than the locked-in mid-hump character of the drive. The result is a pedal that cleans up like a great tube amp. The difference between Adapt Off, I, and II is explored in detail throughout this demo.
Five controls total. Level, Drive, and Tone are the TS classics. The Dry knob adds a parallel clean blend — counterclockwise removes it entirely for traditional TS character, clockwise adds clarity and low-end body. The Voice toggle switches between 808 (classic TS mid hump) and Mod — which shifts the mid hump frequency up for more presence and bite. The Mod voice with Adapt Mode II is its own sound entirely.
Ultra-high input impedance. High-quality buffered bypass. Built in the UK.

Meris LVX — 10 Favorite Stereo Sounds
The most ambitious delay pedal I've ever played. The Meris LVX is not a delay with presets — it is a modular delay system where you design the delay from scratch. Welcome back to Edge of Breakup.
In this episode the Meris LVX Modular Delay System takes center stage — running into the Frank Brothers Ultralight with Lollar El Rayo Humbuckers and Lollar Firebird on a Blender Pot, into the Benson Amps Monarch and Benson 2x12" cabinet. After several weeks with the presets, this is a deep dive into what the LVX actually is and how it sounds when you make it your own.
Most delay pedals give you a fixed architecture: input, delay, modulation, output. The LVX breaks that completely. It features discrete processing elements and control signal modifiers that can be connected in any desired configuration for nearly infinite flexibility. The processing elements include modules drawn directly from the Meris catalog — Polymoon, Hedra, Enzo, and Ottobit Jr., alongside all-new elements including Preamps, Granulize, Cassette, and Poly Pitch.
Each of those elements can be placed in one of four locations in the signal path: pre-delay with dry signal, pre-delay only, in the feedback loop, or post-delay. Put modulation before the delay for classic chorus-then-delay behavior. Put it in the feedback loop and the modulation accumulates with each repeat. Put a preamp in the feedback path and the repeats get progressively hairier. This is the difference between a delay with modulation and a modular delay system.
The onboard display makes navigating the architecture visual and immediate. 99 preset locations across 33 banks, with a Favorite Preset Bank for instant access to three top presets. 2540ms of highly configurable dual delay. 24-bit/48kHz conversion, 32-bit floating-point processing internally. True stereo 60-second looper. MIDI and expression throughout. Digitally controlled analog mix bus.
The LVX reveals its true character in stereo — parked between two amps, the true stereo processing becomes something you feel as much as hear.

Kaisertronics x Edge of Breakup Dual Boost & Fuzz
The ultimate NOS germanium fuzz — designed specifically for this channel. Welcome back to Edge of Breakup.
In this episode the Kaisertronics Dual Germanium Boost/Fuzz takes center stage — this pedal was initially designed for Sean at Edge of Breakup, combining two of Kaisertronics' most beloved circuits into one unit at the channel's request.
The Dual Germanium Boost/Fuzz combines the Damn Germanium Booster (a Dallas Rangemaster-style treble booster circuit) and the Deluxe Germanium Fuzz (a modified Fuzz Face topology) into one enclosure. A combo of NOS TI 2N404 and 2N508 transistors were used in Sean's original unit.
Each side can be run independently or stacked — and the stacking order matters. Run the fuzz into the booster for classic Rangemaster-into-Fuzz-Face character: the booster's Range knob becomes a tone control for the combined fuzz output, letting you dial in everything from dark and woolly to ice-pick treble. Reverse the order — booster into fuzz — and you get wilder, more compressed, cocked-wah-adjacent tones with unique oscillation characteristics.
A bias knob on the fuzz side and internal trimmer controls on both circuits allow deep fine-tuning of each transistor's operating point. Vary the volume of each side independently, adjust the bias, and the tonal variations are extensive.
