A hand-made recreation of the famous Colorsound Power Booster and Overdriver used by the likes of Jeff Beck and David gilmour among the few. We chose to create these as the 9V version as we now live in the power supply world and make life easy for most. We also chose to make these in the later "orange" color as they just look cooler, the brown tone was a tad boring. But you can pick other colors if you so choose ! These are just killer reproductions, in a enclosure that is half the size but while unique it still hints of the original. Inside the unit you will find correct "real" BC109 transistors that just gives it the genuine sound. The beauty of these pedals is the volume pot on the side so you can really push your amp, this gives it the shine of a driven amp mixed with the thick fuzz overdrive tone you want. These pedals are tone machines, always try to use an amp that has some mild grit, the addition of fuzz at that point is the secret to tone. Of course, the Tru-Fi Zoso Fuzz is true bypass, sports LED, and manual ! Made in the USA! NOTE: Swirl Picture - Each one is UNIQUE will slightly different than picture ! NOTE: Swirl Finish and Chrome/Polished Aluminum are $20 extra - Candy Apple Red and Anti-Freeze Green are no extra charge for now !
