"ONE OF A KIND handmade and modified TUBEGRISTLEIZER. The gristleizer was an effect made famous by throbbing gristle which was played by everyone in TG and can be heard on many throbbing gristle recordings, live performances and is still on their solo recordings. The circuit itself is a fairly loud tremelo(VCA)/squelchy filter(VCF) under control of an lfo. The VCA gives you that dark brooding pulsing sound from a slow steady blast to helicopter fast chopping action. with guitar it can sound bassy or razor sharp and rather piercing, with synths it gives movement and can alter harmonic content. the VCF can scream when in self oscillation mode and turns any boring synth or feedback loop tone into a nice sounding near modular beast!
The LFO on the original gristleizer was slightly different, using a switch to change waveshape, the LFO on this circuit uses a pot to alter wave shape from ultra chopy to sloped triangle.saw shapes. This is the signature sound of industrial music! HEAVY pulsing and throbbing beats or lighting fast chop chop!
In addition to the gristle circuit, the effect also has a HI VOLTAGE (200v+) tube preamp/distortion for completely destroying the sound. the circuit was lo fi at first but now its plain garbage! By turning up the gain for the preamp the sound ranges from light harmonic clipping to a blown speaker blasting away. I take no responsibility for damage to amplifiers or recording equipment.
SPECS:
* tremelo/filter switch
* self oscillation switch
* tube power switch
* LFO shape Control
* LFO speed Control
* LFO Depth
* Oscillation Frequency Knob
* Tube Gain
* Tube Input Level
* 1/4" Mono Input and output
* powered by dual 9v and 120vac
No sound samples at this time but there will be videos on youtube by tomorrow night, showing off self oscillation (not on original gristleizer), with guitar or with a simple squarewave bass tone... just search it."

"I'm just about to meet up with Roy Gwinn (literally in a couple of hours time) who wrote the original article back in the 70s for Practical Electronics magazine (he was 16 when he published it!) from which the Gristilizer came.
If you're interested, Clone Analog Gear have a pdf of the article::

Update via Chris Carter in the comments:
"My original Gristleizers were based around the PE kit (PCB & components) produced by Phonosonics in the UK in 1977. I've never made any secret of this, and in fact for a while had the PE schematic on my site. However, I added some mods of my own and designed a completely new case and made units for myself, the band and friends, probably about 10 in total. Cosey's still works to this day but mine was unfortunately 'lost' shortly after appearing in a exhibition in London a couple of years ago. I'm going to upload some photos of an original Gristleizer to my site soon and I'm currently in the process of building myself a replacement.
