Very unusual design, LM393 comparator in linear (almost ;-) mode, NE571 expander for noise reduction and violin-like, slow attack sounds.
- Gain switch:
- Low for dynamic, instrument sensitive distortion
- High for Robert Fripp infinite sustain (adds low end)
The sound is very midrange-focused, no massive bottom, plenty of artificial harmonics, Jeff Beck's Marshalls shrunk into two by four!
Always true By-Pass, 9V battery or power supply.
