Description
The Electro Harmonix Slammi Plus is a fully polyphonic pitch shifter and harmony pedal that delivers everything from subtle detune and lush chorusing through to extreme whammy dives, octave jumps and complex dual harmonies. With up, down and dual shift modes, an X-Fade function and a huge plus/minus three octave range, it gives you studio-grade pitch manipulation in a compact, rugged treadle pedal.
Whether you want to replace a traditional whammy pedal, add fixed interval harmonies to riffs, or morph seamlessly between dry and shifted tones, the Slammi Plus makes it easy. Its digital engine tracks cleanly and glitch free, while the intuitive controls let you dial in anything from musical, expressive bends to wild, experimental sound design.
Polyphonic Pitch Power
The Slammi Plus is fully polyphonic all the time, so it tracks chords, double stops and complex voicings without glitching or warbling. That means you can use it for harmonised riffs, chordal whammy sweeps and ambient pads without having to change your playing style or simplify your parts.
Huge Plus/Minus Three Octave Range
With a transposition range of plus or minus three octaves, the Slammi Plus covers everything from subtle pitch nudges to extreme dive bombs and sky high squeals. You can shift up, down or both simultaneously, opening up creative options for bass-style drops, organ-like octave stacks or synthy, alien pitch sweeps.
Dual Pitch and X-Fade Modes
The Dual setting lets the Slammi Plus generate two independent pitch shifted signals at once. In Pitch mode, both intervals bend together for thick, harmonised whammy effects. Switch to X-Fade mode and the secondary interval becomes fixed, while the treadle cross-fades between dry and shifted tones or between two different shifted intervals, perfect for smooth transitions and evolving textures.
Detune and Fine Blend Control
The 11-position Shift switch includes a D (Detune) setting that shifts by 17 cents for instant chorus and doubling effects without modulation noise. A dedicated Blend control lets you fine tune the balance between dry and wet signals, so you can sit harmonies exactly where you want them in the mix, from barely-there thickening to fully effected pitch sweeps.
Key Features
Fully Polyphonic Pitch Shifting – The Slammi Plus tracks chords and single notes with equal ease, delivering clean, glitch free pitch shifting that works for complex voicings, fast runs and sustained ambient parts.
Plus/Minus Three Octave Range – A massive transposition range of up to three octaves up or down lets you create subtle detune, classic octave effects, radical dive bombs and experimental pitch textures from a single pedal.
Dual and X-Fade Modes – Generate two separate pitch intervals at once and either bend them together or use the treadle to cross-fade between dry and shifted sounds or between two different shifted intervals for smooth, musical transitions.
Rugged, Lightweight Treadle Design – Housed in a tough, weight saving chassis with a traditional rack and pinion mechanism, the Slammi Plus feels familiar underfoot and is built to handle regular gigging while keeping your board light.
