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.

The Boss OC-3 Super Octave is a polyphonic octave pedal capable of generating up to two octaves above and below the input signal simultaneously, with true polyphonic tracking that holds up on full chords rather than just single notes, unlike older monophonic octave pedals. A Drive mode adds a fuzzy, saturated edge to the octave-shifted signal for a thicker, more aggressive texture, while the clean polyphonic mode stays pristine for organ-like layering and thick unison tones. It suits fusion, jazz, and experimental players wanting rich, chord-friendly octave layering, and rock or metal players wanting a heavier, fuzzed-out octave texture.
The Electro-Harmonix KEY9 Electric Piano Machine transforms the sound of a guitar or keyboard into convincing electric piano and percussion tones using EHX's polyphonic tracking engine. It offers nine presets covering classic Rhodes and Wurlitzer voices, including a Dynamo setting that nails the modded Dyno My Rhodes sound that ruled the 1980s, a Wurli preset for the instantly recognizable reed-piano tone, and an Eighty Eight setting emulating a Rhodes 88 with tremolo, plus more unconventional voices like vibraphone and steel drums. Dry and effect blend controls and attack and tone shaping let players dial realistic key sounds. With excellent tracking refined from the earlier B9 and C9, it suits guitarists wanting authentic electric piano textures for studio layering, ambient pads, and live keyboard emulation without a keyboard.
