MXR has debuted the M306 Poly Blue Octave pedal – a redeveloped and rebooted fuzz/pitch-shift/modulation pedal that nods to the brand’s flagship Blue Box unit.
The original Blue Box was used by a handful of electric guitar heroes – such as Jimmy Page, who put it to use on Led Zeppelin’s Fool in the Rain – and favored for its fuzz effect and two octave-down pitch-shift powers.
With the M306, MXR has tapped into the DNA of the iconic Blue Box, while simultaneously introducing a number of new-and-improved specifications.
At first glance, it offers a far more comprehensive approach to pitch-shifting. Featuring a polyphonic/monophonic switch, the M306 boasts four separate octave divisions, complete with their own level controls.
As well as letting users shift their signal down two octaves just like the Blue Box, the M306 features a handful of extra pitch-shifting options: one octave down, one octave up and two octaves up, which are controlled via Sub-1, Sub-2, Oct+1 and Oct+2 knobs.
The Blue Box’s influence can specifically be found in the fuzz department, with the M306 coming loaded with an “unruly fuzz” – said to be derived from the Blue Box’s own effect – that is applied to all signals and tamed by way of the Dry knob and fuzz toggle switch.
Other appointments include an expression output, which allows for expression pedal-operated control of various parameters, and a dual-mode modulation effect that aims to tap into Leslie/Phase 90-style effects depending on which pitch-shifting mode is selected.
It's a far cry more feature-packed than the original Blue Box, which only came with Output and Blend knobs, as well as a single bypass switch.
The M306 is yet to crop up on Jim Dunlop’s website, though it’s currently available to preorder over at Guitar Center for $199.
