Based on the mythical Colorsound Powerboost/Overdriver (which for many is the best booster-overdrive ever made) but improved with the possibility of choosing between Germanium/Silicon transistors and a master-volume for more control. You can use it as a transparent booster to a fuzzy distortion character on both clean and overdriven amps. Our vintage amps will go well with it.

The Colorsound was used by Jeff Beck, David Gilmour, Marc Bolan…
