MXR® Poly Blue Octave M306 – The Ultimate Octave Pedal for Tonecrafters and Sonic Seekers
The MXR Poly Blue Octave brings modern and classic pitch-shifting styles together with fuzz and modulation to create the ultimate octave pedal for tonecrafters and sonic seekers.
Leveled Up – Four Independent Octave Divisions
The Poly Blue Octave features four separate octave divisions—one octave down, two octaves down, one octave up, and two octaves up—each with its own level control. Each is polyphonic by default, meaning they sound just as amazing with chords as they do with single-note passages. Your dry signal gets its own level control, so you can dial in the perfect blend of pitch-shifted tones.
From Contemporary Clarity to Raw Vintage Grit
The Mono switch takes you back to the gritty, monophonic tones of analog-style pitch shifters. In this mode, the sub-octave signals have the warm vibes and raw personality of a pedal like the MXR Vintage Bass Octave, while the higher octave signals resemble the Octavio Fuzz with its fuzz intensity dialed back.
Call Up the Thunder and Lightning
The Poly Blue Octave comes equipped with an unruly fuzz inspired by the classic MXR Blue Box™ Fuzz. Applied to all five signals, the fuzz volume can be adjusted using the Dry knob after pressing and holding the Fuzz button. When used with the sub-octave signals, the fuzz sounds thick and subterranean. Over the higher-pitched signals, the fuzz is searing and synth-like. Run them all at the same time for a choir of thunder and lightning.
Phase Yourself – Dual-Mode Modulation
For infusing your octave tones with an alluring sense of motion, the Poly Blue Octave features a dual-mode modulation effect. In polyphonic mode, the effect provides an uncanny simulation of the famous Leslie effect; in monophonic mode, it provides classic swirls and swooshes inspired by the Phase 90. The Mod knob adjusts the rate—roll it back fully counterclockwise to turn it off.
Step Up and Take Control
Through the EXP jack, you can control various settings with an expression pedal such as the Volume (X)™8 Pedal or an off-board switch like the MXR Tap Tempo Switch to sweep between two different knob and switch configurations or toggle the fuzz and mono modes on and off.
A Full Palette of Tones and Textures in a Single Pedal
The MXR Poly Blue Octave delivers high-performance pitch shifting, fuzz, and modulation in a ruggedly reliable housing with true bypass switching. Put this into your signal chain, and open up new sonic frontiers.
