The Mad Professor Simble Overdrive is a transparent and organic sounding pedal with wide dynamic range. Natural organic tone, un-surpassable touch sensitivity, sweet tube-like compression and built in inspiration. 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. The Simble pedal is happy with either single coil pickups or humbuckers and thanks to the pedals wide bandwidth also works great with bass!
