TOCT OCTAVE REPLICA RTS PCB

The ready-to-solder PCB for our TOCT, a replica of a famously intense vintage octave-up stompbox whose name we can no longer mention, though it starts with "Tycho".

About the effect

This is the most intense of the octave-ups we know of, with the kind of ringing upper-octave fuzz heard on Jimi Hendrix's "Purple Haze" solo. We added a PreGain control to tame the insanity and get more usable octave tones; standard octave sounds come out better with the intensity turned down, while everything on full gives great swells and wild sustain. JD converted the design to an NPN circuit so it runs on the same power supply as most other pedals, and reports the same sound from both versions. The project page also has layouts for an octave/distortion footswitch or toggle switch.

Jumpers are included in the top layer, so there is no need to solder in any jumpers.
