My most challenging build yet - tough, but VERY worth it.
Inspired by the Hoffman ReVibe, it's an all-analog reverb/tremolo combo based on classic Fender versions.
Constituent circuits:
Surfy Bear FET Reverb Cardinal TremoloCustom split/mix circuit for parallel operation
Madbean Bloviator (used as switchable output buffer)
Two 1776 relay bypass boardsOther parts:
Hammond 10" x 6" x 2" amp chassis with walnut sides
Accutronics 8AB2A1B reverb tank (spring unit remounted inside hammond chassis)
Custom faceplate designed by me and laser etched by Mojotone
The Rundown:
The Sufy Bear Reverb uses FETs to emulate the famous 6G15 reverb, with a MOSFET pair driving the tank. I've got this running in a parallel configuration with Midayfair's Cardinal Tremolo, which uses FETs and optocouplers to get a sound similar to Fender tremolos. The modulation settings you see on a rotary switch are Black (blackface/bias), Brown (brown face/harmonic) and Vibe (a univibe-ish sound).
Running in parallel sacrifices the extreme settings of both effects, but the overall lushness of parallel operation was just too good to pass up.
For switching, the soft-touch, momentary switches (thanks to Josh's relay boards) make a big difference because you don't want a hard click clanging the springs. The left switch bypasses the whole unit, while the right switch turns the modulation on & off. I used an Opto Fet to make the Modulation indicator light flash in time with the speed of the effect.
The Bloviator (State variable EQ) on the output is independent and switches on the back. It was on during all the demo samples.
