Two channels of precise, fast tracking polyphonic octaves. You can easily switch between two different “mixes” of dry signal, upper octave and lower octave.
Sometimes a certain piece of music calls for some low-end octave rumble, other times you want to simulate two guitars playing the lower and higher part of the same riff. The 8-Ball allows you to do this without having to reach down and turn the knobs manually.
It also works dandy on bass guitars, keys or even vocals.
The custom designed algorithm analog dry signal (no digital conversion) and buffered bypass keeps your tone intact.

  • Fast, polyphonic pitch shifting algorithm
