Electro-Harmonix Slammi Plus Pitch Shifter / Harmony Pedal

  • Sale
  • Regular price $168.00


This polyphonic powerhouse flawlessly transposes your pitch in two different directions over a +/- 3 octave range: transpose up, down or both, simultaneously! Staggering whammy effects and dive bombs, bends, harmonies, cross-fades between your dry and transposed sounds, cocked pitch shifting... this pedal does it all.

The 11-position Shift switch selects the maximum transposition starting with D (Detune), a shift of 17 cents that creates a chorus or doubling effect. This table details the pitch effect relative to the original note.



The Dual setting outputs two pitch-shifted signals. The first follows the Shift knob as if in UP mode. The second transposed signal depends on whether the Slammi Plus is set to Pitch or X-Fade.

In Pitch mode the secondary shifted signal bends at the same rate as the primary signal. The primary and secondary intervals are as follows:



When in X-Fade mode, the secondary signal is set by the Pitch Mix knob and does not bend. The interval choices are in half-step increments up to +/-1 octave. The volume of the secondary signal decreases by sweeping the pedal from heel to toe.

Featuring a rugged, lightweight design with a traditional rack and pinion style operating mechanism, the Slammi Plus is your ultimate polyphonic pitch shifter harmony pedal.
