Rastop 393 Distortion



Very unusual design, LM393 comparator in linear (almost ;-) mode, NE571 expander for noise reduction and violin-like, slow attack sounds.


  • Volume
  • Drive
  • 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.
