Electro Harmonix Slammi Plus Polyphonic Pitch Shifter Harmony Pedal


Condition: New

Out of stock

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.

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.
