2022-03-22 : Have a look at our MOKA P.O.T. The original production model from GUP Tech.
After hearing about the Harmonic Percolator for such a long time, I guess it was time to try to make a reliable one here at GUP Tech.
The original circuit is a weird fuzzy one, ours is based on the classic schematic, built with modern and available stuff (IE: Cheap and reliable).
If you're here, you probably already know what you'll get, tons of Fuzz, not a lot of controls, only two knobs. We added a clipping bypass, to use it with more volume, and less clipping. It's pretty awesome with single coils pickups. Kick a crunchy amp straight in the face. In upper position, you get the classic Germanium clipping. In center position, you have the bypass/Boost mode. In the lower position, it's classic symmetric silicon clipping.
Disclaimer : This pedal is a huge monster of gain, and with so many components, it will easily go into Squealing mode when you maxed out the knobs if you're using trebly guitars without any buffer. We recommend using a good quality buffered pedal before (or after, you'll need to try) and a clean power supply.
Power consumption : 2mA
