Back in 2005, Electro-Harmonix unveiled the original POG, a polyphonic octave generator that enabled guitarists to conjure everything from the surreal jangle of an 18-string guitar, to rich, thick walls of symphonic sound.The POG2 will take you even higher. Use the new attack control to fade in lush, smooth swells. Tune in the new second sub-octave to reach deeper than ever before. The 2-pole resonant low-pass filter now includes two additional Q modes. Slide in the newly enhanced detune to further refine your sound.The POG2 delivers unrivaled tonal variations - and now you can save your favorite settings, and recall them with a click. The POG2 just plain sounds better, thanks to an enhanced algorithm that delivers a more focused and in-the-pocket harmonic performance. And all this is now packed into EHX's rugged and pedalboard-friendly diecast chassis.Electro-Harmonix POG2 Features:True bypassTotally programmable 8-preset memory with instant recall5 mixable polyphonic octave harmonicsAttack delay slider controls the fade-in speed of the octavesLow Pass Filter with selectable QDry signal can be routed through the Attack, LP, and Detune fadersFlawless polyphonic glitch-free trackingCan be daisy chained with other pedals and power supplies9DC-200 power supply included Electro-Harmonix POG2 Polyphonic Octave Generator Pedal, PSU Included.
