Mad Professor Simble Overdrive Effects Pedal

Product Information

Simble Overdrive has a natural organic tone, unsurpassable 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!

Simble Overdrive is great for Robben Ford or Larry Carlton tone and much more!
