The Kyojin overdrive is a circuit that draws inspiration from the Maxon OD820. Using a dual gain pot and an additional mixer stage to balance the clean signal with the clipped overdriven signal, plus an added gain stage to provide a boost feature. This overdrive sounds and feels very familiar to those who love both the Klone Centaur and the TS808/TS9. As a clean boost it has plenty of power to drive a tube amp into overdrive and you can vary the amount of overdriven signal with the clean signal to get a plethora of driven tones.
