With all of the same distortion and fuzz effects in the original Source Audio Multiwave Bass Distortion but rehoused in a far more compact and sturdy aluminum chassis, the Source Audio Soundblox 2 Bass Multiwave Distortion offers untraditional synth-like sounds plus a clean boost mode to give you a super-versatile bass pedal. Multi-band processing that is uniquely part of the Source Audio Soundblox lines splits up the input signal into distinct bands and applies the effect to each one individually, then rejoining them for a harmonically rich final output.
