MXR Introduces the Poly Blue Octave Pedal

The pedal mainstay's latest offers pitch-shifting with four separate octave divisions in both modern polyphonic and old-school monophonic modes.

MXR new Poly Blue Octave pedal offers four separate octave divisions—one down, two down, one up, and two up and provides controls for each level in the mix along with the option to run through the clarity of polyphonic mode or the raw vintage grit of monophonic mode.

The EXP jack allows you to take control with an expression pedal such as the Volume (X) 8 Pedal or an off-board switch such as the MXR Tap Tempo Switch to sweep between two different knob and switch configurations or toggle the fuzz and mono modes on and off.

Kenny Greenberg with his main axe, a vintage Gretsch 6118 Double Anniversary that he found at Gruhn Guitars in Nashville for a mere $600. “It had the original pickups, but the finish had been taken off and the headstock had been repaired. So, it’s a great example of a ‘player’s vintage instrument,’” he says.

On his solo debut, the Nashville session wizard discovers his own musical personality in a soundtrack for a movie that wasn’t, with stops in Africa and Mississippi hill country.

Kenny Greenberg has been Nashville’s secret weapon for decades. He’s the guitarist many insiders credit with giving the Nashville sound the rock ’n’ roll edge that’s become de rigueur for big country records since the ’90s. It’s the sound that, in many ways, delivered country music from its roots to sporting events.
