If you like to modulate, this could be your new best friend.
Based on the legendary box designed by Roy Gwinn, modified by the equally legedary Chris Carter, and used to destroy all signals in a 5 mile radius of the awesome Throbbing Gristle, this circuit is... legendary and awesome.
With four different wafeforms to play with in both VCA and VCF mode, the sonic possibilities are almost endless, from semi-tame tremolo effects through to extreme filtering and pseudo ring-mod. Use it sensibly or go crazy.
The circuit is happy with all kinds of input levels, so you can play around with your guitar, bass, keyboard, drum machine, toy speak n spell... whatever you fancy.
Includes internal charge pump to get you the 18V required from your standard 9V supply.
This is one of the few kits we'd recommend not board-mounting the pots. The physical depth of the rotary switch means vertical pin pots only just reach the pcb when lined up with it, so wired pots make it easier.
Kit includes: PCB, all components, hook-up wire, 3PDT footswitch for true bypass, high quality jack sockets, DC socket, battery snap, LEDs. Enclosure (pre-drilled) is optional and will not take a battery. Does not include knobs.
PCB size: 82 x 45mm
Knobs required: 5
Direct-Connect compatible (4-way)
