Mashers

Chopper / Masher with audio modulation / cutting input. Extra controls for power starve, loop length. Box print is random pages from Group Sex explosion book. 2 oscillators / flip-flop 'sequencer' / pulse wave modulation input. Controls for pitch, timing, wave fold...

Creeper Delay / Tomb Reverb. PT2399 echo chip based on the Cave Dweller design with high cut filter removed and extra pot to tweak for lowest / longest / most garbled delay / oscillations. Sounds more like old analog delay lines than digital delay. (Clips using blackdeath noise synth as input).

4 oscillator optical theremin with photocell. Frequency pot and volume pot for each osc, plus modulation or straight out options (1234 - out or 1-2, 2-3, 3-4 - out). Also includes power starve pot for extra noise and randomness and a switch for lower frequency pulses.

Chopper MkII. Redesigned circuit and new layout honed down from previous design. Some among you might like to note the lack of fixed resistors (well, ok, there's one) on the board, which means total access to the rawness of the 4001 / 4011s (it also means dead spots as well as minute zones of chaos operating in the confusion zone between 0 and 5 v). 2 main designs, type A with more distortion due to extra feedback loops between the input amp and the cmos, the other some feedback but slightly more 'musical'. Ridiculous fake egghead 'computer music' or a kind of drunken dead batteries Raymond Scott is the nature of type B, as illustrated in the mp3. Note that input source should be line level, and that sources such as cmos theremin, mashers etc will tend to blend more with the circuit producing modulation etc whereas inputs such as tape will be 'cleaner', like a tremelo.
