Recently, Smashing Guitar issued a limited commercial version of The Gristleizer, the custom audio effects unit that Throbbing Gristle used in the late 1970s to create uneasy listening music and define the industrial music genre. TG co-founder Chris Carter had made the first unit based on a design printed in Practical Electronics magazine. Now, Smashing Guitar has built a run of thirty Gristleizers in a stompbox form-factor. From the product description:
 Files The-Gristleizer-StompboxThe pedal version, housed in a high-quality, heavy-duty Hammond 1590DD box, retains all the functionality of the tabletop design with the added convenience of footswitch operation. In essense, The Gristleizer is a synth module that works with any audio signal. The audio path is modulated by an LFO using four selectable waveforms (upslope, downslope, triangle, & square), functioning in one of two paths: VCA (voltage controlled amplifier) or VCF (voltage controlled filter). Ranging from light and sweet tremolo to extreme, raunchy ring mod, The Gristleizer is a 100% analog, hand-assembled unit built to last.
