The Positron Preamp Drive pedal is designed to replicate the overdrive tone of the Gorilla TC-35 Tube Cruncher amplifier. The Gorilla amps were known for their unique overdrive sound, which caught the attention of Josh Homme from Queens of the Stone Age.

Unlike traditional overdrive pedals that use clipping diodes to create distortion, the Positron relies on overloading the opamp to achieve its overdrive tone. This is typically considered an undesirable characteristic, but in this circuit, it works to create the desired sound.

The Positron is a direct clone of the TC-35’s preamp section, based on the original factory schematics. It operates on the same voltage as the original amplifier but is designed to be used as a standalone drive pedal rather than a true preamp.

Overall, the Positron Preamp Drive offers guitarists the opportunity to capture the unique overdrive tone of the Gorilla TC-35 amplifier in a compact pedal format.
