Gristleizer - Mad Modulations!
New version with the waveform rotary switch on a separate daughterboard to make lining everything up just dandy.
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 waveforms 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.
