The Xotic Effects BB Plus takes Xotic's already impressive BB Preamp a step further by adding another channel and more controls!  The Xotic BB Plus is so transparent and versatile it bridges the gap between fingertips, guitar, and amplifier with a full spectrum of sounds. Channel A epitomizes the core of the original BB Preamp. It has an amp-like feel, exhibiting characteristics that are very open with rich complex harmonics. Channel B is the most versatile booster Xotic has ever designed. At any setting, it delivers the most inspiring musical tone that only dreams are made of. Activate both channel stacks simultaneoussly, and select the order of the channels (A into B, or B into A), for unlimited configurations of superb tone.

It’s capable of 30dB+ clean boost with adjustable ±15dB two band active EQ’s which adds a wide range of harmonic content for your ideal sound. The BB also utilizes a pre-gain stage which provides a range of sounds from a very pristine clean to a very compressed smooth overdriven sound.
