The Xotic Effects BB Preamp is the golden standard of overdrive pedals and has always been one of the most popular pedals from Xotic. At its core, it is capable of up to +30db of clean boost without effecting the original tone, but as you dial up the active gain control, it will give you silky smooth overdrive with great natural compression. This pedal is perfect acting on its own as an overdrive pedal, but also works wonders when added on top of an overdriven amp. The BB Preamp has been used by countless pro players, including Andy Timmons, Steve Lukather, and Lee Ritenour. It is the perfect addition to any serious guitarists pedal board. Like every Xotic pedal it is true bypass and is made with only the finest components. The BB can be powered by an optional power adaptor or a 9V battery.
