Pump'd Up Tone Bender Kit

This kit includes all of the parts needed to build the GuitarPCB Pump’d Up Tone Bender project. This circuit is based upon the Sola Sound Tone Bender Professional MKII, and uses vintage germanium PNP transistors for vintage tone.  Traditionally, fuzz circuits like the Tone Bender™ which have PNP transistors have required a dedicated power supply, since they are positive ground circuits. This project circuit board is designed with a charge pump section which allows the pedal to have power daisy-chained with other pedals on the same power supply. These kits include hand-measured, matched sets of vintage germanium transistors, each of which is marked with gain and leakage values. Please note that the transistor brand/model may vary, but all will be in TO-5 packages.


The Pump'd Up Tone Bender Kit includes a 125B enclosure and Davies 1510-style knobs.


All of our kits include a jack for a DC power adapter but no battery snap. If you wish to add a battery snap, please add a battery snap kit to your cart in addition to the pedal kit. Please see what is provided in a kit? in our FAQ for more details of what is included and what you will need to provide to complete the project.
