The Walrus Audio Luminary Quad Octave Generator uses the tremendously powerful SHARC DSP chip to produce a polyphonic party on your pedalboard. With separate level controls for each of the four octaves, a wet/dry blend and synth-like controls for shaping the attack and filter, the Luminary offers up a wealth of sounds to gently enhance or completely mangle the input signal. Change things up on the fly using the expression pedal input, and even store up to four sounds with three presets and the "live mode" for easy recall in between songs.
