From Xotic:

The BB Preamp offers a wide variety of sounds. It’s capable of a 30dB+ clean boost with an adjustable +/-15dB two band active EQ which adds a wide range of harmonic content to your ideal sound. The BB also utilizes a pre-gain stage which allows the Pedal to go from a very pristine clean to a very smooth, compressed, overdriven sound. True Bypass for eliminating any signal interference when switched off.”

Brand new.
