Explore A New World Of Polyphony With The Electro Harmonix Slammi Plus Pitch Shifter & Harmony Pedal

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. 

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.

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.



  • Flawless, glitch-free transposing over a +/- three octave range
  • Three shift modes: up, down and dual
  • Dual pitch shifting mode where the Slammi Plus generates two separate pitch shift intervals simultaneously
  • An X-Fade function where the pitch shift interval is fixed (does not bend) and the foot pedal cross-fades between your dry note and pitch shifted note or cross-fades from one pitch shifted interval to another
  • Fully polyphonic all the time
  • More flexibility in setting the heel position’s pitch shifted interval
  • A Blend control that lets you fine tune the wet/dry mix
  • Runs on battery or most 3rd party power supplies including the EHX9.6DC-200mA PSU
  • Rugged, weight saving chassis with a traditional rack and pinion style operating mechanism
