Electro-Harmonix Polyphonic Octave Generator

Despite its industrial looks, this pedal is not built to take much abuse, especially with its exposed plastic sliders. Unlike most octavers, the POG tracked perfectly across the entire range of the bass (including open strings), and it handled chords with nary a warble, though its digital conversion yielded a slightly cold, clinical tone. Additionally, the POG has a lowpass filter that acts like an EQ rolling off high frequencies. If detuned upper-octave effects aren’t your cup of tea, you may want a pedal with a little less going on—but if you’re looking for a solid basic octave effect with a lot of crazy new sounds, the POG might be a good choice.
