The Purple Nurple overdrive pedal is best used in front of an amplifier that is already/on the verge of distorting on its own. By adjusting the VOLUME and GAIN knobs, you can achieve sounds ranging from a slight boost to a smooth distortion.
At low volumes BMF's Purple Nurple can be used as a mild fuzz pedal. With an amp on the verge on breaking up, it can be used as a clean boost or use the gain knob to dial in more grit. Have an amp that has a great low gain sound? Use the Purple Nurple to add even more gain. Think of the Purple Nurple as an enhancement to a tube amp that is on the verge of or breaking up on its own.
The Purple Nurple overdrive pedal can be powered by either a 9v battery or with a negative tip 9v power supply.
All BMF Effects pedals come with a transferrable five (5) year warranty with the exception of the foot switch which carries a three (3) year limited warranty from the date of purchase.
