The Xotic Bass BB Preamp is a distortion booster gives bass players a lot of choices in a super-small package. You can dial in anything from a clean boost to wildly overdriven distortion with this tiny pedal, and know that you'll always be able to hear each individual note with just a hint of compression for extra smoothness. Its two overlapping EQs offer up to 15dB of boost or cut for even more tonal shaping.
