Electro-Harmonix SLAMMI PLUS – effects pedal

The Electro-Harmonix Slammi Plus is a high-precision polyphonic pitch shifter pedal designed for guitarists, bassists, and experimental sound designers. With impeccable tracking across a ±3 octave range, this pedal allows you to transpose, detune, harmonize, or blend two voices with surgical precision.

The 11-position Shift switch lets you select everything from a subtle 17-cent chorus to extreme ±3 octave jumps, while also allowing you to choose the direction (Up, Down, or Dual). X-Fade mode allows you to seamlessly crossfade from a dry signal to a transposed signal (or between two different intervals), adding a new dimension to your live performances or studio sessions. A dedicated Blend control lets you fine-tune your wet/dry mix to preserve articulation and natural dynamics, even with complex multi-chord passages or single notes. The robust rack-and-pinion mechanism and compact size make the Slammi Plus ideal for pedalboards where accurate pitch control, glitch-free tracking, and versatile routing are crucial.

Whether you're creating atmospheric pitch textures, dizzying leads, or dynamic harmonic layers, this pedal offers modern innovation in pitch shifting.
