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 Boss MO-2 Multi-Overtone is a pitch-shifting and harmonics pedal using Multi-Dimensional Processing (MDP) technology to blend adjustable overtone harmonics with the dry signal. Three modes provide different harmonic combinations: Mode 1 adds one octave up with mild modulation, Mode 2 adds one octave up and one octave down with rotary-speaker-style modulation, and Mode 3 adds one octave down with upper harmonics and moderate modulation. Controls include Balance, Tone, Detune, and Mode. Mono and stereo outputs. Reviewed by Premier Guitar and MusicRadar.

The T-Rex Quint Machine is a polyphonic harmonizer from T-Rex Effects (Silkeborg, Denmark), generating five simultaneous harmonized voices from a single note or chord for massive, full harmonic stacking. The Quint Machine provides multi-voice harmonization for players who want rich, stacked harmonic textures beyond conventional single-interval harmonizers.
