  • Glitch-free transposing over a +/-3 octave range
  • Three Shift Modes: Up, Down, and Dual
  • Dual Pitch Shifting mode enables Slammi Plus to generate two separate pitch shift intervals simultaneously
  • X-Fade mode keeps the pitch-shift interval fixed (does not bend) while 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
  • Added flexibility in setting the heel position's pitch-shifted interval
  • Blend control lets you fine tune the wet/dry mix
  • Runs on a 9V battery (included) or most third-party power supplies including the EHX 9.6 VDC/200mA PSU (sold separately)
  • Traditional rack and pinion style operating mechanism




                  The Slammi Plus Polyphonic Pitch Shifter/Harmony Pedal from Electro-Harmonix transposes your pitch in two different directions over a +/-3 octave range (transpose up, down, or both) simultaneously. The 11-position Shift switch selects the maximum transposition starting with D (Detune) which is 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.
