The Mad Professor Simble Overdrive MK2 is an improved version of the legendary Simble Overdrive, created for guitarists who want natural drive without losing the core sound of their instrument. Its transparent, organic voice makes it ideal for players who need expressive touch response, musical compression and a wide dynamic range.
Revisited together with original designer Lassi Ukkonen, the MK2 version offers a more open sound, increased headroom and added brightness from the Contour control, helping it work effortlessly with a wide range of guitars and amplifiers. From subtle clean boost to “on the edge” crunch and sweet singing overdrive, the Simble Overdrive MK2 delivers refined gain with excellent feel and clarity.
With Level, Sensitivity, Contour and Accent controls, this pedal gives you precise control over output, distortion, compression, tone, pick attack and brightness. True bypass switching, 9–12V operation and battery or DC power compatibility make the Mad Professor Simble Overdrive MK2 a professional, pedalboard-friendly choice for blues, classic rock, country, fusion, studio work and expressive lead playing.
