Electro-HarmonixSlammi Plus Polyphonic Pitch Shifter/Harmony Effects Pedal
1/7
Independent shopping perspective
The Korena take
Slammi Plus is a polyphonic pitch-shifting and harmony pedal with up, down, and simultaneous two-direction transposition across a ±3-octave range. Its controls cover pitch bends, dive-bomb-style shifts, harmonies, dry/transposed cross-fades, and fixed-position pitch effects. The 11-position Shift switch sets the maximum interval; the D setting applies a 17-cent detune associated with chorus or doubling. In Dual, a second shifted signal can follow the main bend or remain set by the Pitch Mix control, depending on the selected mode.
Strong match
Who this is for
- Creating pitch-bend, dive-bomb, harmony, and dry-to-transposed cross-fade effects from one pedal.
- Using Dual mode when two independently described shifted signals are needed.
