Manufacturer's Description

THE LEGENDARY TRANSPARENT OVERDRIVE

The Simble Overdrive Mk2 is an improved version of the original Simble, a transparent and organic sounding overdrive with wide dynamic range. This natural sounding overdrive pedal can work as a clean boost, ”on the edge” crunch, or a sweet singing overdrive, always retaining the core tone of your instrument.

WHAT'S NEW?

We revisited the circuit with the original designer Lassi Ukkonen to bring his preferred improvements to this legendary pedal. The outcome was more open sound, more headroom and brightness from the contour to work effortlessly with any instrument.
