This Amp is Still Surprising Me | Benson Amps Vincent

Benson Amps returns to the channel with a full dedicated showcase of the Vincent head — 30 watts of cascading Vinny into Chimera/Monarch-esque clean channel magic. Welcome back to Edge of Breakup.

In this episode the Benson Amps Vincent head and Benson 2x12" cabinet take center stage — featuring the BilT Guitars DK Ultra S.S. Zaftig with Lollar La Prima Mini-Humbuckers and Emerson Custom Treble Bleed, into Scumback H75-PVC speakers via the Boss Waza Tube Amp Expander. The Benson Amps Preamp and Germanium Fuzz feature from 10:17 onward.

Benson Amps: https://www.bensonamps.com/guitar-amplifiers

The Benson Amps Vincent is a 30-watt channel-switching amplifier with a genuinely unique architecture: it cascades a 1-watt Vinny Dirt Channel into a 30-watt Chimera/Monarch-esque Clean Channel. The Vinny Dirt Channel is the pre-gain stage — a warm, harmonically rich 1-watt gain circuit that feeds directly into the front end of the 30-watt Clean Channel. The result is an amp that produces a Monarch-style clean tone at its foundation but can be driven by the Vinny circuit for pushed and cranked tones that feel organic and amp-driven rather than pedal-driven. The only Benson amp with an onboard effects loop — tube powered, placed post-Vinny and pre-Clean Channel power amp gain.

Three core tonal zones explored in this demo: the clean channel alone from 03:53 — wide, open, and detailed; the clean channel pushed with the Benson Preamp pedal as the gain source from 10:17; and the fully cranked clean channel boosted first by the Benson Preamp and then by the Benson Germanium Fuzz from 20:51. The Vinny Dirt Channel activated at 25:40 in Low Gain mode and 28:50 in High Gain mode, boosting the already-cranked Clean Channel from below.

Two-band EQ. Tube powered effects loop. Boss Waza Tube Amp Expander used here for light attenuation with reverb duties added post-Vincent pre-and-power-amp gain, pre-speaker cab.

Get that Sparkle and Sizzle Back in Your Tone! | Emerson Custom 1 Meg Premier Pro Pots

Emerson Custom returns to the channel with their brand new 1 Meg Premier Pro Potentiometers — and they are a game changer for Jazzmaster-style guitars. Welcome back to Edge of Breakup.

In this episode the Emerson Custom 1 Meg Premier Pro Pots take center stage — installed in the Black Bobbin Chicago Phantone with Lollar '63 Jazzmaster Pickups and Emerson Custom Treble Bleeds, into the Benson Amps Vincent 2x12" with Scumback H75-PVC speakers via the Boss Waza Tube Amp Expander. The Keeley-modded Ibanez TS9 Tubescreamer and Effectrode Tube Vibe feature throughout.

Lollar '63 Jazzmaster Pickups: https://www.lollarguitars.com/63-jazzmaster

The Emerson Custom Premier Pro Potentiometers were three years in development — born out of frustration with COVID-era supply chain failures and Mitch's refusal to settle for the industry norm that CTS pots are "good enough." The result: a completely in-house designed and manufactured pot built from the ground up to Emerson's own specifications. Fiberglass substrate instead of the phenolic used in most guitar pots — significantly stronger, more rigid, won't bend or snap. Proprietary 20% audio taper — 20% output at half rotation — designed to feel and respond the same way in both volume and tone positions, with an unusually musical and smooth sweep across the full travel. 8% tolerance (920K–1080K Ω on the 1 Meg version). Oversized solder lugs for clean wiring.

The 1 Meg value is the correct resistance for Jazzmaster and Jaguar circuits — the original Fender offset designs were spec'd at 1 Meg throughout, which gives the pickups a different loading characteristic than the 250K or 500K pots used in most other guitar wiring. Lower pot resistance bleeds off more high frequency content from the pickup; the 1 Meg value keeps the full frequency response of the pickup intact. Combined with the Emerson Treble Bleed and the proprietary 20% audio taper, the volume knob cleanup explored from 10:51 is one of the most responsive and musical cleanup sweeps on the channel.

The Keeley-modded Ibanez TS9 is Robert Keeley's famous modification to the classic Ibanez Tubescreamer — one of the most well-known and sought-after boutique modifications in pedal history. Keeley's TS9 mod targets the tone-coloring capacitors and op-amp circuit within the TS9, opening up the frequency response and increasing the headroom and clarity of the overdrive character. Used here as both an overdrive and a clean boost to slam the Benson Vincent's clean channel from 07:09 onward.

The Best Vintage Style Fuzz! | R2R Electric Replica Series MKII Fuzz

R2R Electric returns to the channel with something truly special — the Replica Series MKII Fuzz, serial number 3, won at eBay auction in a fight to the finish. Welcome back to Edge of Breakup.

In this episode the R2R Electric Replica Series MKII Fuzz takes center stage — featuring the Gibson Custom Murphy Lab 1964 SG Standard in Aged Pelham Blue with Righteous Sound RAF A4/A2 Humbuckers and Emerson Custom Prewired Kit, into the Benson Amps Vincent 2x12" with Scumback H75-PVC speakers via the Boss Waza Tube Amp Expander. The Effectrode Tube Vibe joins from 08:58.

Follow R2R Electric: https://www.instagram.com/djlavalamp
Coming soon on the channel: R2R Electric Replica Series MK1.5, serial number 2 — subscribe so you don't miss it.

The R2R Electric Replica Series represents the pinnacle of Chris Vincent's builds — a part-for-part, component-for-component recreation of original vintage fuzz circuits using the exact same types of components used in the original pedals. Not inspired by or based on — as close to an exact replica as possible. The MKII Fuzz is Chris's recreation of the 1966-1969 Sola Sound Tone Bender MKII — the two-transistor germanium fuzz that became the defining British fuzz circuit of the late 1960s, used extensively by Jimmy Page, Jeff Beck, and the early Rolling Stones. Serial number 3 of this build. NOS vintage germanium transistors, NOS passive components throughout, hand-wired point-to-point. Place first in signal chain before any buffered bypass pedals.

The Gibson Custom Murphy Lab '64 SG Standard in Aged Pelham Blue is part of Gibson's Murphy Lab program — Tom Murphy's proprietary aging process applied to new Custom Shop builds, using scientifically reverse-engineered nitrocellulose lacquer identical to what Gibson used in the 1950s and 1960s. The 1964 SG Standard is the model associated with George Harrison and Eric Clapton, featuring the dependable Maestro Vibrola that replaced the earlier clunky sidepull vibrato, and a neck profile increased in size resembling the profile found on 1959 Les Pauls. Solid lightweight one-piece mahogany body. Mahogany neck, authentic '64 medium C profile. Indian rosewood fingerboard, hide glue fit. 24.75" scale. 22 frets. Cellulose nitrate trapezoid inlays. ABR-1 bridge. Murphy Lab Light Aged hardware throughout.

The Righteous Sound RAF (Righteousness Applied For) A4/A2 set is a vintage accurate PAF replica — butyrate bobbins, USA-made pole screws and slugs, custom fabricated nickel PAF clone covers with no copper undercoat, long-legged vintage accurate threaded baseplates, period correct 42awg plain enamel wire, vintage single braid wire. Alnico 4 neck (~6.9K) / Alnico 2 bridge (~7.5K) — the A4 neck delivering open, airy clarity, the A2 bridge providing vintage warmth without compression.

Fuzz Face & Rangemaster in One! | Expresso FX Dual Ge / Si Fuzz & Ge Boost — AC125 / CV7347 / OC45

Expresso FX returns to the channel with another custom Dual Ge/Si Fuzz & Ge Boost build — this time in the chameleon color enclosure, with a completely different transistor set and a genuinely special result. Welcome back to Edge of Breakup.

In this episode the Expresso FX Custom Dual Ge/Si Fuzz & Ge Boost (Chameleon) takes center stage — featuring the Fender Custom Shop 1960 Journeyman Relic Stratocaster with Righteous Sound Pickups Opal Road Set and Emerson Custom S5B Blender 5-Way Wiring Kit and Treble Bleed, into the Benson Amps Vincent 2x12" with Scumback H75-PVC 65W speakers and Benson Tall Bird+ Reverb and Tremolo Unit via the Boss Waza Tube Amp Expander.

Reach out to Sof on Instagram DM for current inventory: https://www.instagram.com/expressofx/ Learn about the Dual Ge/Si Fuzz & Boost: https://expressofx.com/product/custom-dual-ge-si-fuzz-ge-boost-gorva-chameleon/

This is Sof's custom three-circuit pedal combining a Fuzz Face/Tone Bender hybrid fuzz with switchable germanium and silicon middle transistor, and a Rangemaster-style germanium treble boost — all in one enclosure with independent footswitches. Every transistor hand-selected NOS, zero compromise on components.

Ge Fuzz side (00:00): Three transistors — AC125 germanium in Q1, CV7347 silicon in Q2, AC125 germanium in Q3. The AC125 is a warm, full-frequency NPN germanium device from the early 1960s with smooth cleanup response and excellent harmonic complexity. The CV7347 is the military specification Mullard silicon device — grittier, more aggressive, with more upper-mid bite. Placing a silicon transistor in the middle position of a three-transistor circuit produces a hybrid character that sits between a pure germanium Fuzz Face and a pure silicon Tone Bender MKI — the warmth of the outer AC125s with the aggression of the CV7347 in the critical middle gain stage. Explored across the full opening section.

Si Fuzz side (10:05): The switch positions are compared directly — the Si Fuzz voice gives the CV7347's silicon character more prominence in the mix. Explored from 10:05 to 12:59 against the Ge Fuzz for direct comparison.

Ge Boost side (12:59): OC45 germanium transistor — the Mullard OC45, used in the earliest Dallas Rangemaster units. Authentic treble boost character with the warmth and harmonic complexity of the original circuit. Explored slamming the Benson Vincent into breakup territory.

Benson Tall Bird+ Harmonic Tremolo explored from 17:36. Fuzz stacked into Ge Boost from 19:19.

The Boutique Guitar Maker You NEED to Know About! | Gronlund Guitars SC18

Gronlund Guitars makes its channel debut — and you'll be seeing a lot of the SC18 in upcoming demos. Welcome back to Edge of Breakup.

In this episode the Gronlund Guitars SC18 takes center stage — TV Jones TV Classic Filter'Tron pickups, into the Benson Amps Vincent 2x12" with Scumback H75-PVC speakers via the Boss Waza Tube Amp Expander. The Expresso FX Ge Boost (Philips OC141) and Effectrode Tube Vibe feature from 04:59 onward.

James Greene builds Gronlund Guitars in his small shop on the coast of Maine — every guitar rough cut from kiln dried hardwood, handcrafted from scratch. James combined his love for music and craftsmanship to design a unique line of instruments that prioritize tonal balance, playability, and individual character. Each build ships in a Mono Vertigo case.

The SC18 is a single-cut semi-hollow — part thinline, part semi-hollow, with one f-hole rather than two and the acoustic complexity that brings. One piece Honduran Mahogany body. Maine Hard Maple neck. African Ebony fretboard and headstock face cap. 59' C neck profile (.860" at first fret, tapering to .960" at 12th). Set neck. Satin nitrocellulose lacquer, hand rubbed with 0000 steel wool for a low luster brushed finish. 500k CTS audio pots with treble bleed. Orange Drop capacitors. Switchcraft output jack. TonePros wraparound bridge.

This build is fitted with TV Jones TV Classic Filter'Tron-style pickups in humbucker-sized rout — Tom Jones' flagship model, the one Brian Setzer chose in a blind test against vintage pickups during his Gretsch signature development. Warm, clear, and chimey with that unmistakable Filter'Tron character. The SC18's semi-hollow Mahogany construction gives the TV Classics more acoustic body to work with than a typical solid guitar, producing a particularly resonant and open result across all positions.

Expresso FX Buzzabout Fuzz

Expresso FX returns to the channel with the Buzzabout — Sof's faithful reproduction of the Colorsound Buzzaround circuit. Welcome back to Edge of Breakup.

In this episode the Expresso FX Buzzabout takes center stage — featuring the BilT Guitars DK Ultra S.S. Zaftig with Lollar La Prima Mini-Humbuckers and Emerson Custom Treble Bleed, into the Benson Amps Vincent 2x12" with Scumback H75-PVC 65W speakers and Benson Tall Bird+ Reverb and Tremolo Unit via the Boss Waza Tube Amp Expander.

Learn about the Buzzabout: https://expressofx.com/product/buzzaround/

Also on the channel: Expresso FX Fuzz Bender MKI, Ge Fuzz, Octave Fuzz, Ge Boost, and MK1.V.

The Colorsound Buzzaround is a lesser-known British fuzz circuit from the late 1960s — related to the Tone Bender family but with its own distinct architecture and character. Strong, loud fuzz tones with great sustain and relatively low background noise compared to other circuits of the era. Sof's Buzzabout is a faithful reproduction using the highest quality NOS components throughout.

Transistors: Newmarket CV7007 and Mullard OC42 germanium, hand-selected. NOS Sylvania germanium diode. NOS Mullard Mustard C296 polyester capacitors. NOS Philips electrolytic capacitors. NOS Allen Bradley carbon composition resistors. Premium Cliff UK jacks. 22 AWG solid core silver-plated copper wire with Teflon insulation. Lead-free silver-based solder. True bypass. Genuine Hammond aluminium enclosure, powder-coated. 3 years warranty.

Three controls: Fuzz, Volume, Tone. The all-knobs-cranked territory is explored from 02:31, with volume knob cleanup from 04:01 — the Buzzaround's interaction with the guitar volume control producing its own specific character distinct from the Fuzz Face or Tone Bender circuits covered in previous Expresso FX demos on the channel.

Your Search for Mini-Humbuckers is Over | Lollar La Prima Mini-Humbuckers

Lollar Pickups returns to the channel with the La Prima Mini Humbuckers — and the BilT DK Ultra S.S. Zaftig is the perfect host. Welcome back to Edge of Breakup.

In this episode the Lollar La Prima Mini Humbuckers take center stage — installed in the BilT Guitars DK Ultra S.S. Zaftig, into the Cunningham Amps Custom 35 2x12" via the Boss Waza Tube Amp Expander. The Madsen Amplification Ge Boost features from 05:30 onward.

Buy a set of Lollar La Prima: https://www.lollarguitars.com/laprima

The Lollar La Prima was originally developed as a miniaturized version of the El Rayo humbucker — and while it shares the El Rayo's touch sensitivity and responsiveness, the tonal character is distinctly its own. Sweet chiming highs, scooped mids, tight low end. Neck 3.3K / Bridge 3.8K. No typical humbucker compression — the La Prima responds to subtle changes in picking technique and guitar volume in the way a well-voiced single coil does, while still canceling hum.

The BilT Guitars DK Ultra S.S. Zaftig is a chambered offset built from reclaimed old growth pine from the structural support beams of the BilT Guitars headquarters in Des Moines, Iowa — 300-year-old wood, now chambered and hollowed for acoustic resonance and light weight. The La Prima's open, articulate character has unusual space to develop in a chambered old growth pine body. Built by hand at BilT, no CNC machines.

The Madsen Amplification Ge Boost — Maynard Madsen's point-to-point Dallas Rangemaster-style NOS germanium boost from Camdenton, Missouri — features a three-way input cap selector (explored across its positions from 05:30) and pull-down resistors to eliminate footswitch pop. Originally a numbered limited run of 30 units. Explored with volume knob cleanup from 07:29.

Benson Amps returns to the channel with the Tall Bird+ — their flagship all-tube spring reverb and optical tremolo unit, and a ground-up original design. Welcome back to Edge of Breakup.

In this episode the Benson Amps Tall Bird+ Tube Reverb & Optical Tremolo takes center stage — running in the Benson Vincent effects loop, between the Vinny Dirt Channel and the Clean Channel, into the Benson Vincent 2x12" with Scumback H75-PVC speakers via the Boss Waza Tube Amp Expander. The Benson Amps Germanium Preamp, Germanium Boost, and Germanium Fuzz all feature throughout.

Benson Amps: https://www.bensonamps.com/guitar-amplifiers

In Benson's own words:

"The Tall Bird Plus is our flagship all tube driven spring reverb and optical tremolo. A ground up original design with the goal of attaining the classic 60s sounds but with added functionality and improved noise characteristics.

Independent WET and DRY controls — the dry control can be used to overdrive an amp, or remove the dry signal completely. The ROOM control creates a high pass filter: turn it down for classic drip sounds, or up for cavernous hall style reverb. Three-pole adjustable oscillator drives the neon lamp for extremely slow or extremely fast tremolo settings. Switchable optically driven standard OR harmonic tremolo — true bypass tremolo takes the optical circuitry completely out of the signal path to prevent volume loss issues of the original circuits. Tube driven output buffer for driving long cables. Dual LED footswitch with included TRS cable. A grounding schema lifted from hi-fi stereos that prevents noisy ground loops. The reverb bypass disconnects the send signal to the reverb tank, allowing for trails rather than a hard cutoff.

Hi-Fidelity vs. Natural Mode: the Tall Bird Plus performs similarly to a high quality buffer and makes treble frequencies pop more than expected. The rear-panel switch compensates — Hi-Fidelity for technically unaffected tones, Natural Mode for a more expected response. Harmonic tremolo quirk: when engaged with depth all the way down, some light bass throbbing may occur — select standard tremolo or bypass via footswitch if bothersome."

The Tall Bird+ runs here in an unusual but highly effective position: in the Benson Vincent effects loop, after the Vinny Dirt Channel and before the Chimera-esque Clean Channel. This means the reverb and tremolo are processing the driven signal from the Dirt Channel, with the Clean Channel's character coming after — a specific placement explored extensively throughout the demo. The Dry knob's ability to overdrive the amp is explored from 03:36, with the signal path providing a unique way to push the clean channel into breakup without adding a separate overdrive.

In Tim Cunningham's own words:

"The Custom 35 is an all tube guitar amplifier available in both head and combo configurations. Two channels are foot switchable for running independently, in parallel or cascaded modes providing a diverse tonal palette ranging from crystalline cleans to high gain tube saturation.

Channel 1 — Bite — Tweed style: big juicy cleans through to 'dimed on 12' overdrive. Channel 2 — Body — British style: classic Plexi tones for crunchy rhythm and singing leads.

In parallel mode, Channel 2 blends on top of Channel 1 — similar to jumpering channels on a dual channel amp. In cascade mode, Channel 2 borrows an additional gain stage from Channel 1 for modern high gain tones. Cathode biased output stage — fitted with EL34s as standard, try 6L6 or KT66 for a unique tonal signature. Tube driven spring reverb standard."

The Cunningham Amps Custom 35 is loaded with Scumback H75-PVC and S75-PVC 12" speakers, 8 ohm, 25W each.

The Cunningham Amps MK1.6 Fuzz sits at the intersection of the MK1.5 Tone Bender and Dallas Arbiter Fuzz Face — Tim's hand-crafted take on the classic mid-1960s two-transistor fuzz circuit, built one pedal at a time with NOS transistors individually voiced and matched per build. This unit features Texas Instruments 2N404 germanium transistors — NOS, hand-selected. The three-way Gain Mode switch is the key creative control: Low (bright, boost-style fuzz with strong volume knob cleanup response — explored from 06:52 and 09:45), Med (progressively more fuzz and low end), High (full saturated fuzz, fat and juicy). Attack and Level controls cover the full range from clean boost through face-melting fuzz. Each build comes with a custom carry bag, signed and numbered certificate of authenticity.

Lollar Firebird: https://www.lollarguitars.com/lollar-humbucker-pickups/firebird

The Prisma Diavolo is Nick Pourfard's LP-style single-cut — built in California, every build one-of-a-kind. This Diavolo features a skateboard hard rock maple top: seven-ply compressed maple decks laminated together, each carrying its own color patterns and patina, making the visual result entirely unrepeatable. Maple C neck (87-97 profile). Reclaimed Brazilian Walnut fingerboard from the Coney Island Boardwalk. 25.5" scale. 1 5/8" bone nut. 6105 nickel frets. Emerson Custom wiring kit and Treble Bleeds. Schroeder Wraparound Bridge — lightweight aluminium body, stainless steel clips, brass saddles.

The pickup configuration is the highlight. Lollar Gold Foil neck and bridge are the primary two-pickup voices — chimey, articulate, complex midrange character that sits between single coil and humbucker without sounding like either. The Lollar Firebird middle is wired to a push/pull on the bridge tone pot, bringing it in as a third voice that can be blended with the neck, bridge, or both simultaneously. All three pickups activated together (06:32), neck + Firebird middle (07:01), and bridge + Firebird middle (05:52) are all explored — the Firebird's compressed, vocal mid-forward character adding a completely different dimension to the Gold Foils' naturally open sound.

The Madsen Amplification Ge Boost — Maynard Madsen's Dallas Rangemaster-style NOS germanium boost with 3-way cap selector, from Camdenton Missouri — slams the Cunningham Tweed channel from 08:54. Three-way cap positions explored: mid boost, treble boost, and full frequency.

The Best P90 Pickups?! | TV Jones T-90 Pickups

TV Jones makes its channel debut with the T-90 — a P90-voiced pickup in Filter'Tron format, available in Filter'Tron, humbucker, and P90 soapbar sizes. Welcome back to Edge of Breakup.

In this episode the TV Jones T-90 Pickups take center stage — installed in the Tone Ranger Guitars Sunset Rider with Bigsby B5, into the Cunningham Amps Custom 35 2x12" with Scumback H75-PVC speakers via the Boss Waza Tube Amp Expander with Echo Fix EF-X3 Tape Echo in the loop. R2R Electric Rangemaster OC44 and Effectrode Tube Vibe feature in the second half.

Check out the TV Jones T-90: https://tvjones.com/shop/guitar-pickups/t90/ Follow TV Jones: https://www.instagram.com/tvjonesinc/

The TV Jones T-90 is Tom Jones' answer to a specific tonal question: what happens when you take the hum-cancelling construction of a Filter'Tron and voice it to sound like a P90? The result is a pickup that has the P90's characteristic midrange aggression, bite, and snarl without the single-coil hum — and that can be ordered in Filter'Tron size, standard humbucker size, or P90 soapbar size, making it a direct drop-in for almost any guitar routing without modification.

The Filter'Tron-sized version is installed here in the Tone Ranger Guitars Sunset Rider — Jeff Mark Leavitt's latest model from his one-man LA shop, built from urban liquidambar body and headcap, urban black acacia neck, urban Indian rosewood fretboard. Bigsby B5 tailpiece, Mastery M1 bridge, CTS 500k audio taper pots. The combination of P90-voiced pickups and the Cunningham Custom 35's Plexi channel — explored from 00:00 — is explored across all three positions, with volume knob cleanup from 01:39 and the Rangemaster + Tube Vibe combination from 06:03.

The Best NOS Tone Bender MKI?! | Expresso FX Fuzz Bender MKI

Expresso FX makes its channel debut with the Fuzz Bender MKI — Sof's immaculate reproduction of the original three-transistor Tone Bender MKI circuit. Welcome back to Edge of Breakup.

In this episode the Expresso FX Fuzz Bender MKI takes center stage — featuring the Wide Sky Guitars P125C Cutaway with Curtis Novak P90s and Emerson Custom Treble Bleeds, into the Cunningham Amps Custom 35 2x12" via the Boss Waza Tube Amp Expander.

Reach out to Sof on Instagram DM for current inventory — he works in batches and drops small quantities at a time: https://www.instagram.com/expressofx/
Learn about the Fuzz Bender MKI: https://expressofx.com/product/fuzz-bender-mk-i/

Expresso FX is Sof, building in the UK with zero compromise on components. The Fuzz Bender MKI is his recreation of the earliest three-transistor-based fuzz circuit from the Bender family — the 1965 Sola Sound Tone Bender MKI, the circuit that predates the Fuzz Face derivations and produces the distinctive nasty, spitting, cutting, midrange-forward character that defined the earliest British fuzz tones. In Sof's own words: "an immaculate reproduction of a classic pedal, but with a few tweaks for performance and reliability improvements."

Transistors: Newmarket CV7007 in Q1, Mullard OC82D in Q2, and Mullard OC42 in Q3 — all hand-selected NOS. NOS Mullard Mustard C296 polyester capacitors. Philips electrolytic capacitors. NOS Allen Bradley carbon composition resistors. Premium Cliff UK jacks. 22 AWG solid core silver-plated copper wire with Teflon insulation. Lead-free silver-based solder. True bypass. Genuine Hammond aluminium enclosure, powder-coated. 3 years warranty.

Three controls: Level, Filter, and Attack. The Filter knob is the key addition over the original MKI two-knob layout — it controls the low-end content feeding the fuzz stage, explored from 03:03 for tightening and shaping the circuit's bottom end. The Attack knob is explored across its full range from 03:21. Lower Amp gain with the MKI level reduced produces a ragged, more open-top end character explored from 05:24.

Tone Ranger Guitars Double Barrel

Tone Ranger Guitars returns with the Double Barrel — Jeff Mark Leavitt's double-cut two-pickup build with Lollar Gold Foil pickups and a Bigsby B5. Welcome back to Edge of Breakup.

In this episode the Tone Ranger Guitars Double Barrel takes center stage — Lollar Gold Foil set, into the Cunningham Amps Custom 35 2x12" via the Boss Waza Tube Amp Expander with the Echo Fix EF-X3 Tape Echo in the loop. R2R Electric Rangemaster OC44 and Effectrode Tube Vibe feature in the second half.

In Jeff's own words: "Tone Ranger Guitars grew from my love of the West: the culture, the environment, the music, and the history of the western American deserts and forests. Lovingly hand-crafted in my one-man shop in LA with the finest components and pickups, Tone Ranger Guitars are made entirely from sustainable, local, urban trees from Los Angeles and her surrounding counties. These trees lined our city streets, shaded our parks, and grew in our backyards — now rescued by arborists such as Street Tree Revival and Angel City Lumber who repurpose these beautiful trees and give them a second life. You're a Tone Ranger now. Keep on truckin'."

The Double Barrel is Jeff's double-cut two-pickup solid body — 24 frets and a Bigsby B5 for glassy shimmer. Full specs (Serial #0103225):

Urban California redwood body with figured urban black walnut top. Urban black walnut neck. Urban Indian rosewood fretboard. Thin D neck profile. 24.75" scale. Set neck. 24 frets, 12" radius. Jescar 55090 medium/highest nickel silver frets. Bone nut. 7.4 lbs. Lollar Gold Foil set. CTS 500k audio taper volume pot with treble bleed. CTS 500k audio taper tone pot with 47nf Illinois Capacitor film cap. Centralab 3-way toggle. PureTone multi-contact jack. Tone Pros T3BP tune-o-matic. Bigsby B5. Grover Sta-tite 18:1 tuners. Nickel hardware. Black top hat knobs. No pickguard. Hand-rubbed Walrus Oil finish. Silkscreened headstock logo. Made in Los Angeles, California.

The Lollar Gold Foil is Jason Lollar's take on the DeArmond-style Gold Foil pickups from the 1950s and 1960s — chimey, articulate, with a complex midrange character that sits between a single coil and a humbucker without sounding like either. In the figured walnut and redwood Double Barrel, the Gold Foils' natural brightness and mid complexity pair beautifully with the Cunningham Custom 35's Tweed channel.

TV Jones TV Classic Pickups

TV Jones makes its channel debut — and the Tone Ranger Guitars Sunset Rider is the perfect showcase. Welcome back to Edge of Breakup.

In this episode the TV Jones TV Classic Pickups take center stage — installed in the Tone Ranger Guitars Sunset Rider (humbucker-sized rout), into the Cunningham Amps Custom 35 2x12" via the Boss Waza Tube Amp Expander. The R2R Electric Rangemaster OC44 and Effectrode Tube Vibe join for the second half.

The TV Jones TV Classic is Tom Jones' flagship Filter'Tron-style pickup — the one Brian Setzer chose in a blind sound test against multiple vintage pickups during the development of his Gretsch signature model. This version is built for standard humbucker-sized routing, making it a direct drop-in upgrade for any humbucker-routed guitar that wants brighter, tighter Filter'Tron character without any modification to the body.

The TV Classic in the Sunset Rider's liquidambar and black acacia body with Mastery MV vibrato is explored here in a compact five-chapter format — bridge pickup into the Cunningham Plexi channel, volume knob cleanup with the R2R Rangemaster, neck pickup, Univibe tones, and then Rangemaster fully cranked. The CTS 500k audio taper pots and the Mastery vibrato's tuning stability are highlighted throughout.

Wolfetone Pickups Meaner P90 Bridge — Feat. Grez Mendocino Jr. & Jules Leyhe, Blues Guitarist

Wolfetone Pickups makes its channel debut — and Jules Leyhe is here to show you what the Meaner P90 can do. Welcome back to Edge of Breakup.

In this episode the Wolfetone Meaner P90 Bridge Pickup takes center stage — Jules Leyhe on the Grez Guitars Mendocino Junior, into the Cunningham Amps Custom 35 2x12" with Scumback H75-PVC and S75-PVC speakers via the Boss Waza Tube Amp Expander. The R2R Electric Supa MKI Fuzz also features.

The Wolfetone Meaner P90 is hand-wound by Wolfe Macleod with Alnico 2 magnets, wound to approximately 9K — slightly hotter than vintage output and built specifically for the bridge position. The Alnico 2 magnets give it the warm, aged character of an original P90 whose magnets have settled and de-gaussed over decades, without the harsh upper mids that Alnico 5 bridge P90s can produce. The Meaner's character: midrange raunch and nastiness with brightness and presence that cuts through without ever getting spiky. In Jules' hands and through the Cunningham Custom 35's Tweed and Plexi channels, it covers everything from clean singing tones to full-gain fuzz with the R2R Electric Supa MKI.

The R2R Electric Supa MKI Fuzz is a limited build of just 12 units — Chris Vincent's take on the Marshall Supa Fuzz MKI circuit, the late 1960s amp builder version of the Tone Bender MKI family. NOS 1960s Philips OC75 germanium transistors, hand-selected and matched. Vintage passive components throughout, hand-wired point-to-point. As with all R2R vintage fuzz builds: place first in signal chain before any buffered bypass pedals.

The Wolfetone Meaner P90 in Jules' Grez is a hand-wound Alnico 2 P90 wound to approximately 9K — slightly hotter than vintage output, with midrange raunch and nastiness that defines the Meaner's character. Bright and forward but not harsh, full but not muddy. The Alnico 2 magnets give it the warm, aged character of early P90s.

The Prisma Guitars Dillinger Baritone is Nick Pourfard's LP-style model built in baritone configuration — tuned to B standard. Skateboard hard rock maple top over mahogany back, maple neck, Coney Island Boardwalk Brazilian Walnut fingerboard, Lollar Gold Foils, Mastery Bridge and Tremolo, Emerson Custom wiring kit and Treble Bleeds. Every Prisma skateboard top is a unique 1/1 original deck, making each build unrepeatable. Baritone B standard and Gold Foils into the Supa MKI — explored from 13:33 — is a genuinely unusual and compelling combination.

The Sunset Rider conjures the unique guitar designs of 1960s Japan — front and rear bevels and contours for players of all body types, with a narrowed upper bout that keeps the horn away from the chest or abdomen, letting the smaller body sit closer to the player for a more intimate feel. Full specs (Serial #0501524):

Urban liquidambar body and headcap. Urban black acacia neck. Urban Indian rosewood fretboard. Soft V neck profile. 24.75" scale. Set neck. 22 frets, 12" radius. Jescar 55090 medium/highest nickel silver frets. Bone nut. 7.8 lbs. TV Jones TV Classic set. CTS 500k audio taper volume pot. CTS 500k audio taper tone pot with 22nf Orange Drop. Switchcraft 3-way toggle. PureTone multi-contact jack. Mastery M1 bridge. Mastery MV vibrato tailpiece. Grover Deluxe tuners. Nickel hardware. Witch hat knobs. No pickguard. Hand-rubbed Walrus Oil finish. Silkscreened headstock logo. Made in Los Angeles, California.

The TV Jones TV Classic is Tom Jones' flagship Filter'Tron-style pickup — the one Brian Setzer chose in his blind sound test against multiple vintage pickups during the Gretsch signature model development. Warm, full, and clear with that unmistakable Filter'Tron chime. The Mastery MV vibrato gives the Sunset Rider smooth, accurate vibrato that stays in tune where vintage floating tremolos notoriously don't. The audio taper pots contribute to one of the most musical and expressive volume knob cleanup sweeps in this demo — explored in depth from 06:17.

R2R Electric Uniform Fuzz

R2R Electric returns to the channel with the Uniform Fuzz — a limited collaboration with LA's Uniform Music, and one originally designed for low-frequency instruments. Welcome back to Edge of Breakup.

In this episode the R2R Electric Uniform Fuzz takes center stage — featuring the Grez Guitars Mendocino Junior with P90 pickups, into the Benson Amps Monarch via the Boss Waza Tube Amp Expander. The Effectrode Tube Vibe and Echo Fix EF-X3 Tape Echo also feature.

Follow R2R Electric: https://www.instagram.com/djlavalamp/ R2R Electric mailing list: https://www.r2relectric.com

The Uniform Fuzz is a limited collaboration between Chris Vincent (@djlavalamp) and Uniform Music in Los Angeles. The circuit was originally conceived to work especially well with baritones, Bass VI, and electric bass — instruments that push fuzz circuits into the low frequency range where many vintage fuzz designs thin out, gate unexpectedly, or lose their character. The Uniform Fuzz is voiced to handle that low-end content without those issues, while still delivering the full NOS germanium character that defines every R2R Electric build.

That low-frequency voicing translates musically to guitar as well — demonstrated throughout this demo on the Grez Mendocino Junior's P90 pickups, which have their own natural fullness and body that benefits from a fuzz circuit that doesn't thin out in the low mids. The Bias knob's sweep is explored from 03:30 — at high bias the fuzz opens up and blooms; at lower bias the circuit becomes more gated and compressed. The Level control has substantial range above unity, explored from 01:39 and 04:21 to push the Monarch's front end harder.

All NOS vintage germanium components, hand-wired point-to-point as with every R2R Electric build. Place first in signal chain before any buffered bypass pedals.

Brothers AM — Chase Bliss x Analog Man

Chase Bliss returns to the channel — and Analog Man makes their first appearance. Together they've made the best thing to ever happen to the King of Tone. Welcome back to Edge of Breakup.

In this episode the Chase Bliss x Analog Man Brothers AM takes center stage — featuring the BilT Guitars DK Ultra S.S. Zaftig with Lollar La Prima Mini-Humbuckers, into the Cunningham Amps Custom 35 2x12" via the Boss Waza Tube Amp Expander.

Buy a Brothers AM: https://www.chasebliss.com/brothers-am

The King of Tone is one of the most coveted overdrive pedals ever built. Analog Man's Mike Piera has been building them entirely by hand with near-unobtainable parts since the early 2000s — the waitlist has run as long as seven years. Five years ago, Chase Bliss founder Joel Korte sent Mike an email asking if he'd like to collaborate. The Brothers AM is the result.

The Brothers AM is not a clone of the King of Tone. It takes the coveted circuit, works closely with Mike Piera on its recreation, adds advanced control, and includes a treble boost circuit inspired by Analog Man's Beano Boost. The modes, hidden settings, and preset options from the KOT are now front-panel accessible controls that can be changed on the fly.

At its core: two identical, independent, multi-mode gain channels. Each channel selectable between Boost, Overdrive, and Distortion. Each has Gain, Volume, and Tone controls, plus a Presence control accessible by holding the footswitch and turning the Tone knob. Use Side 1 into Side 2 for stacking, or run either channel independently.

The Treble Booster is the bonus circuit — inspired by Analog Man's Beano Boost, the Rangemaster-inspired treble boost built with a vintage silicon transistor that Joel found to best capture the essential character. Three-way toggle: Yellow (Lite — softer treble boost character), Off, Red (Full — more aggressive). The Treble Booster can be positioned pre-Side 1 to slam it harder, or it can feed directly into Side 2. All the permutations explored throughout the demo from 02:40 onward.

16 dipswitches for high-gain mode per channel, linked Presence, and additional behavior options. 4 internal preset slots. Ships with Chase Bliss favorites including a recreation of Mike Piera's own preferred settings. Full MIDI, CV, and expression pedal control over every parameter.

I own two original King of Tones. They have totally nailed this.
