Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.38% — somewhat different

The DigiTech Whammy is a foot-controlled pitch-shifting pedal capable of tracking up to two octaves up or down in real time via its expression treadle, producing the classic dive-bomb and rising pitch-bend effects associated with alternative rock and experimental playing. Modern versions track smoothly and naturally through wide pitch shifts, avoiding the glitchy, warbling artifacts that plagued earlier pitch-shifting technology, though harmony modes can still show a touch of digital character on fast note-to-note transitions. It also handles polyphonic pitch shifting, letting full chords bend and harmonize rather than just single notes. It suits players wanting dramatic, expressive pitch effects, dive bombs, rising swells, harmonized leads, or on-the-fly drop tunings, controlled hands-free via the treadle.
The Electro-Harmonix Slammi Plus is a polyphonic pitch shifter and harmony pedal combining glitch-free pitch shifting over a plus or minus three-octave range with a built-in treadle for expressive whammy-style sweeps. An 11-position Shift switch selects the interval, from Detune for chorus and doubling through minor and major seconds, thirds, fourths, fifths, sixths, and one, two, or three octaves. A Dual Mode outputs two pitch-shifted intervals at once for harmonies, and an X-Fade function fixes the interval and crossfades between dry and shifted notes or between two shifted intervals. Tracking is fast and glitch-free even on chords, making it work for guitar, bass, and synth. It functions as a Pitch Fork and expression pedal in one and is often compared favorably to the DigiTech Whammy.
