MXRM306 Poly Blue Octave Effects Pedal - Blue
1/6
Independent shopping perspective
The Korena take
MXR's Poly Blue Octave is a blue octave pedal for guitarists and bassists with three voice modes: Bass, 12-String, and Poly. Bass mode adds a tone one octave below a guitar signal, while 12-String mode doubles it one octave up. Poly creates octave layers above and below the dry guitar tone. Volume, Tone, and Mix controls let you set the effect level, voice it, and blend it with the unaffected signal. Its die-cast chassis, footswitch, and jacks are built for stage use.
Strong match
Who this is for
- Filling out a guitar arrangement with a bass tone one octave below the original signal.
- Creating a doubled octave-up part that recreates a 12-string guitar sound.
- Blending upper and lower octave layers with dry guitar tone through the Mix control.
