The Bass Micro Synthesizer reissue has the same incredible features as the Micro Synthesizer with a filter sweep range tailored for lower frequencies. From percussive sounds to backwards sounding bowed sounds, the Bass Micro Synthesizer, with its four completely mixable voices (bass, octave above, sub- octave, and square wave or distortion) and adjustable filter sweep section lets the bass player create those fat vintage analog synthesizer sounds heard on records by everyone from Bootsy Collins to the Chemical Brothers.
