The Gristleizer!

The Gristleizer is a Crazy sounding effect that can go from being a subtle tremelo to over the top synth/spaceship sounds with the flip of a switch.

Basicaly it's Voltage Controlled Amplifier(VCA) or Voltage Controled Filter(VCF) that can be modulated by 4 different waveforms.

Designed by Roy Gwinn, the circuit was originally printed in 1977 in a UK magazine Practical Electronics.

Chris Carter from the Pioneering Industrial band Throbbing Gristle started making versions of the Gristleizer for his band mates and friends and it soon became an integral part of the bands recordings and live shows.

This pedal was built using a version of the circuit designed Taylor Livingston and "Slacker" (from the forums).
In the video I am running a MOOG Little Phatty straight in to the gristleizer with no other effects.

Here is a company selling the Gristleizer for $375.

When I made my personal Gristleizer I made a couple of extras. If anybody is interested I would be willing to sell one for much less than $375.


  1. Quite a cool box!

    How can I contact you? I would be interested to have one of these.. Thanks!

  2. I am interested as well.

    let me know. thanks!

  3. If you still have any of these, hit me back.

  4. I'd be also keen if you wanna make some more..

  5. Are you still checking this blog? I'm interested in what you're up to with this stuff, if you have items you sell, circuit diagrams you'd be willing to share... whatever. I love the two videos, love the sound of the "Gristleizer," and the Blue Lunchbox is the best WSG enclosure I have seen to date. I hope you get this message and can reply to a fellow bender. --pete.spaker@gmail
