Similarity
citedBlended 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.

Description

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.

The DigiTech HammerOn is a pitch and octave pedal that delivers instantaneous pitch jumps over a four-octave range, letting players use their feet to hammer onto notes beyond their hands' reach for faster, more intricate phrases. It has two independently programmable footswitches, a rapid-fire Trill function, and a DRY+ mode that adds harmony to the dry signal. In Impossible mode it alternates hammer-on pitch shifts between two programmable pitches, while Sequence mode steps through fully chromatic Drop and Capo transpositions. Engaging Trill produces techno-like note sequences with two, three, and five-note options plus tap tempo. Marketed as combining the power of seven pedals in one, it suits experimental, electronic-leaning, and lead players wanting playable pitch effects, drop tunings, and rhythmic trills from a single unit.
