'66 Fender Princeton Reverb | Vintage Amp Showcase | Feat. Giordano Guitars Veloce & Sunbear Pickups

The 1966 Fender Princeton Reverb — genuine vintage black panel from 60 years ago, and a whole lot of tone and pedal territory to explore. Welcome back to Edge of Breakup.

The 1966 Fender Princeton Reverb takes the spotlight, paired with the Giordano Guitars Veloce — Sunbear SB-62PAT# Humbuckers, Emerson Custom Treble Bleeds. The Cunningham Amps Zonk MKI Fuzz, Origin Effects Deluxe 55, and Effectrode Tube Vibe all make appearances.

The Princeton Reverb's black panel AB763 circuit is one of the cleanest, most neutral platforms in the entire vintage Fender catalog — no inherent grit or coloration baked into the amp itself, just headroom, chime, and that famous mid-scoop. That neutrality makes it a genuinely great canvas for testing what different pedals actually do to a signal, rather than a starting point that's already coloring the tone before anything gets stomped on.

The Sunbear SB-62PAT# Humbuckers in the Giordano Veloce — short-length Alnico V magnets referencing the brief Gibson transitional era between the PAF and Patent Number decal — bring a bright, spanky character reminiscent of the best vintage SG pickups. The Emerson Custom Treble Bleeds keep that clarity fully intact through every volume knob sweep, across clean tones and everything that gets layered on top.

The Cunningham Amps Zonk MKI Fuzz — Tim Cunningham's hand-built take on the Hornby Skewes Zonk Machine, a close cousin of the Tone Bender MKI with its own angular, midrange-forward character — is the first stop into genuine vintage fuzz territory, giving the neutral Princeton a raw, gnarly edge.

The Origin Effects Deluxe 55 shows up as a guest — an all-analog recreation of the 1955 Fender 5E3 Tweed Deluxe, deliberately paired with the black panel Princeton rather than a real tweed amp, to see whether the pedal can genuinely pull that tweed character out of a neutral platform rather than just confirming it on an amp that already sounds tweed-ish. Push-pull power amp simulation with reactive load, cathodyne phase inverter recreation, a Preamp switch toggling between 12AY7 and 12AX7 valve character, and a Tone control that adds gain as it's turned up — all built to mimic exactly how the real 5E3 behaves, not just how it sounds.

The Effectrode Tube Vibe closes things out with rich, three-dimensional modulation on top of whatever gain stage came before it.

The Decker Amp Co. Hummingbird 20 — featuring Colin Decker's lovely cleans and gain, 2 band EQ, exclusive 3-voice reverb circuit and all-tube power scaling — paired up with my 2002 Gibson Custom Shop Les Paul R8 Historic, Ron Ellis LRP Humbuckers, wired with my signature Emerson Custom x Edge of Breakup Les Paul Prewired Kit & Emerson Custom Treble Bleeds on both volumes. The R2R Electric Klone (Serial #004) and R2R Electric x Henri Cash Cash Boost both feature.

Handbuilt entirely in California, Decker amplifiers capture the warmth and soul of classic tube amps while offering the touch-sensitivity, reliability, and features modern players need. Drawn from Colin Decker's decades of playing, touring, and modifying amps for studio and stage, Decker amps are original designs reflecting his "just play" philosophy — cathode-biased circuits for harmonic richness, simple controls that keep you focused on playing, and responsive combos that feel alive in the room.

The Hummingbird 20 succeeds the Hummingbird 15 — and the improvements are substantial. All-tube power output attenuation across six profiles: 20W, 18W, 15W, 10W, 5W, and 1W — true output-tube attenuation. The Spaces reverb circuit adds three selectable size and depth voicings.

Cathode-biased, Class A design.

2x 6V6 2x ECC83, 1x ECC832 reverb tube. Controls: Volume, Low, High, Reverb Mix + 3-space selector.

Solid AA Eastern White Pine, finger-jointed, AA Baltic Birch baffle and rear panels, poplar and pine cleating, stainless steel hardware, signature Decker heavy-duty leather handle.

30 lbs unpackaged. 22"W x 18"H x 10"D.

Designed, manufactured, and assembled 100% by hand in the USA.

Pedals: The R2R Electric Klone, Serial #004, is Chris Vincent's exacting take on the Klon-style transparent overdrive, hand-wired with the same no-compromise NOS component philosophy behind every R2R build. The Cash Boost is Henri Cash's (Starcrawler) signature germanium boost — a collaboration between Henri and Chris Vincent, close friends in the LA music and gear scene — built as a faithful reproduction of a 1960s Dallas Rangemaster circuit.

The Hummingbird 20 aims squarely at the conversation the internet has been having about the Deluxe Reverb being "the best amp ever," and makes the case that THIS might be the real answer.
