This bluesy bruiser is effectively two pedals in one - a tonally transparent booster that gives your solos that extra lift, and a truly valve-like overdrive that's so rich in 2nd order harmonics it'll make your guitar gently weep while you wail. If that's not enough, the BB-2's completely passive bypass means that you don't lose a single drop of your guitar's pure tone when the pedal's not in use!
