The MXR Bass Preamp pedal gives new voice to your passive basses in a tidy, compact enclosure. Separate input and output controls for a range of gain staging possibilities team up with a switchable pre/post 3-band EQ with sweepable midrange to dial in the drive and tone you desire to your amp while a studio-quality direct output goes straight to your mixer or interface. This workhorse pedal helps shape your sound in more ways than one and is the perfect companion for your bass both in the studio and on the stage.
