One of the most convincing D-Style compact pedals, the Mad Professor Simble, just like a real Dumble, lets you EQ the signal before or after the overdrive. The Accent control adjusts the brightness before the drive, and Contour sets the brightness after the drive stage. It can really sing with humbuckers and almost sounds better with them over single-coils.
Check out the videos of it. We added it to our super-thorough guide to the best Dumble-style pedals.
Mad Professor Simble, Builder’s Notes
A TRANSPARENT AND ORGANIC SOUNDING PEDAL WITH WIDE DYNAMIC RANGE, DUMBLE AMP IN A BOX
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!
