From Iron Ether:

Create massive, multi-faceted and shimmering sounds with the Polytope four-voice detuner/chorus/vibrato.

The Polytope creates up to four copies of the input signal, which can be detuned in pitch from subtle thickening to huge multi-voice detuned synth sounds. The detuned voices maintain the timbre of the input and respond well to polyphonic signals. In addition to the static detune mode, the included LFO (low frequency oscillator) can be used to sweep the pitches of all four voices to create wide and deep chorus ensembles when combined with the clean signal.

Removing the clean signal allows for true pitch vibrato, from slight wavering to tape-style wow and flutter, slow seasick wobbles and high speed FM synth-style modulation. A switchable high-pass or low-pass filter applies the detuning only to the chosen frequency range.

The detuning amount, or chorus/vibrato depth, can be controlled with an expression pedal, for a variety of expressive and unique effects.

The controls are extremely wide-ranging, covering classic sounds and extending into spaced-out madness.

Pedal is designed to look worn. In excellent condition.

Pedal only.
