This is my version of a Marshall Super Bass preamp. It uses 5 Jfets (no IC's or clipping diodes!) to emulate the original amp. On this one, I designed and etched my own pcbs for the main and charge pump (see internal picture). It comes in a 125B enclosure with all top jacks (Lumberg). I used high quality WIMA capacitors and has a relayed true bypass. It has an internal charge pump that is on a top mounted mini switch that allows it to run on either 9 volts or 18 volts (cleaner) so use a 9 volt power supply only. I'm only going to make ONE available for order (the one pictured).
Quick soundclip of the pedal:
