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.

Persuasion. 5 product stars
"As a big fan of TG I've always wanted my very own gristleizer and as they are not in production except in EuroRack mode at the moment this kit is the best solution on the market. It's not a difficult build and sounds absolutely amazing! You can sculpt out some classic industrial soundscapes from it but it is not a one trick pony either. It's an extremely deep pedal and in some modes is more of an instrument than an effect. Buy, build and and lose yourself in a world of wibbly-wobbley wonderfulness!" eddnix - 30 November 2019

You might not need it - but you want it! 5 product stars
"Awesome Circuit! VCA mode does everything from standard tremolo to helicopter, VCF could have been a wah wah in a former life. I love it! Cheers 3" Isaac Neutron - 13 March 2019
Cool, but fiddly because of wires! 5 product stars
"Good kit. This is one you have to wire the pots to, not hard but this took the longest out of the 5 kits I bought from here. Tip, if you wire in a switch Jack between the middle leg of the depth pot you can input CV. It'll work backwards (CV high, VCA/VCF close) tho." Pish - 27 July 2017
