Subdecay Harmonic Antagonizer



There’s no reverence for 1960’s fuzz tradition here. There are no germanium transistors or NOS parts. It’s not polite or smooth. The Harmonic Antagonizer is not your typical fuzz box. In fact the fuzz moniker is really inadequate. It’s really more of a fuzz / oscillator / chaos synthesizer / tone destroyer / noise machine, etc. It’s not just for guitar either.
It’s great on bass, drum machines or just about any instrument you can plug in to it.
The essentials of this effect boil down to a square wave converter and a triggered oscillator. There’s more going on inside to turn that in to something that can be musical.


The square wave converter creates the fuzz sound. The oscillator is triggered for an effect similar to the sync function on a synthesizer. The voltage controlled amplifier keeps the output from hard gating as the input trails off. There are no hard rules here. How you use it is up to you.

Getting started:

On the back page there is an explanation of the controls, but really this is the kind of effect where you just have to plug it in and use it.


Input impedance: 1M
Output impedance: Less than 10K
Power by DC adapter. (see back for more details) or 9 volt alkaline battery.

Operation and care:

All the regular stuff here. Don’t leave it out in the rain or put it in an oven. If you want to clean it use a towel, don’t put it in the washing machine. Send it back to us if it stops working.
