P.U.T.B. – The Best Tonebender PCB available


The Best Tonebender PCB with a Modern Twist. Works with other negative-ground pedals.

In stock


This is the Classic Tonebender with a modern twist. Pump’d Up means you can use this circuit with other negative-ground pedals. Since the power section has no effect on the Audio Path, utilizing a Charge Pump to invert to a modern negative ground circuit will not affect the tone of an original Tonebender. This will allow you to daisy chain or use it in a combo build.

Because many old PNP fuzz pedals tend to be positive-ground circuits, they must have a separate power supply from the rest of your effects in a chain. To overcome this limitation, a charge pump chip has been integrated to invert the power to a negative ground circuit allowing it to be powered by the same source as all of your other effects with ZERO effect on tone!
