mad professor simble
The new Simble Overdrive pedal from Mad Professor is designed by amp wizard Lassi Ukkonen who has serviced, fine-tuned and modified the best amplifiers in the world and has built into this pedal what the best amplifiers are all about: natural organic tone, touch sensitivity and sweet tube-like compression. This natural sounding pedal works as a clean boost, ”on the edge” crunch, or a sweet singing overdrive, always retaining the tone of your prized guitar.


  • SENSITIVITY: Amount of distortion and compression
  • LEVEL: Output level
  • ACCENT: Pick attack and brightness
  • CONTOUR: Brightness of the output

Available April 2014.
