The Source Audio Ultrawave Multiband Processor is a groundbreaking distortion and effects pedal that splits your guitar, bass, or synth signal across multiple frequency bands—each with independent drive and output controls. Choose from 37 band-splitting configurations and 44 distortion types including Tube, Diode, Foldback, Octave Up, and Negative Flip Diode to craft thick, rich tones with dynamic overtones. Beyond overdrive, the Ultrawave delivers a dual-channel compressor/expander, 8-band graphic EQ, multiband tremolo with detailed LFO controls, and sound morphing via expression pedal or envelope follower.

Access up to 128 presets via MIDI, control parameters with an external expression pedal, and customize all four knobs for on-stage flexibility. Features stereo ins/outs, adjustable noise gate, USB connectivity for the Neuro Desktop Editor, and your choice of analog buffered or true bypass. Built into a compact, durable aluminum housing measuring 4.5" × 2.75" × 2", the Ultrawave represents over a decade of refinement in multiband processing technology. A used unit offers exceptional value for players seeking professional-grade sound design and performance control. This pedal is in good condition.
