Unlock expansive sonic possibilities with the MXR Poly Blue Octave Pedal. This powerhouse combines four independent octave divisions—ranging from two octaves down to two octaves up—with a gritty fuzz circuit inspired by the legendary Blue Box and dual-mode modulation that captures both Leslie and Phase 90 textures. Mix and match your pitch-shifted tones with independent dry signal control for ultimate tonal flexibility. Whether you're chasing thick, subterranean depths or soaring synth-like highs, the integrated fuzz adapts to your sound. Add expression pedal or footswitch control for real-time tweaking on stage. Built tough with true hardwire bypass and powered by 9V battery or AC adaptor, this is the octave pedal that delivers studio-grade effects in a road-ready package.
