Description

The Classic Tonebender with a modern twist. Pump’d Up means you can use it with other negative-ground pedals because the charge pump changes the circuit to Center Negative Polarity while retaining 100% of tone in the Audio Path.

Because PNP fuzzes are positive-ground circuits, they must have a separate power supply from the rest of the effects in a chain. To overcome this limitation, a charge pump chip has been integrated to allow this board to be powered by the same source as all of your other effects. All with ZERO effect on the tone!
