The Blues Pearl “Blue Balls” pedal may have a politically incorrect name, but once it's at your feet all bets are off. The BB-1 can go from a mild overdrive, to a distortion that fills in all the holes from rhythm to lead work. This pedal cuts though but keeps it cool. It's one of a kind design helps provide 1st, 2nd, and 3rd order even harmonic structure that you can feel not just hear. This is again, a one of a kind design that has a special input buffer that allows the unit to respond much like a tube amp and helps keep those high smooth but present sweet midrange as well . This is just one more of the sought after pedals from the original line-up, now available in its new package. Blues Pearl products have always been known to be built like a tank and these pedals are nothing short of that.
