The MXR M306 Poly Blue Octave Pedal is a colossal box of tone. Theres a staggering array of effects to explore in a single pedal thatll keep you experimenting all night. With no less than four separate octave divisions available you can send your tone plummeting down the registers for some unctuous bass or soar up through the pitches to reach dizzying high notes. Combine all those octaves together or separately and mix in the fuzz mono dry/wet and expression pedal options and you have an almost unlimited palette of sonic creation. Whatever sound is in your head you can bring it to life it on the MXR Poly Blue. It simply cant be overstated just how versatile and varied this delightful stomp box is. Offering dual-mode modulation your effects are boosted with phaser like momentum be that a thick undulating slow swirls or a frenzied frantic dash. Set into the polyphonic mode you have access to textures resembling the famous rotary Leslie effect while the monophonic switch evokes the swooshes and dips of MXRs celebrated Phase 90 pedal. And for those times you dont want to draw on the considerable power of the M306 its default off bypass mode will ensure your signal is unaffected no matter where you place this on your pedalboard.

MXR
MXR’s first product was the Phase 90, released in 1972. Dunlop’s official MXR history traces the early line from that compact phaser to the Distortion+, Dyna Comp compressor and Blue Box octave fuzz—circuits that remain central reference points for the brand. JustPedals carries those classic families alongside the Carbon Copy analog delay, Micro Amp, Talk Box and bass effects. MXR’s range is deliberately broader than one effect category: compare the model number and version, especially where a classic circuit has later reissues, mini enclosures or expanded controls.

Octave Pedals
An octave effect generates notes one or more octaves above or below the input. Analogue circuits often create raw monophonic sub-octaves, while digital pitch tracking can follow chords and provide several intervals with cleaner separation. Tracking speed, polyphonic accuracy, latency and the balance of dry, upper and lower voices determine whether the result feels tight, organ-like, synthetic or deliberately unstable.
