Gristleizer - Mad Modulations!

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.

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.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is only available with full kits, and will not take a battery. Knobs are not included.

Difficulty: Medium

PCB size: 82 x 45mm

Knobs required: 5

Enclosure: 1590BB

Direct-Connect compatible (4-way)

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 - 27/07/2017
