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 Eddy is an analog vibrato and chorus pedal that pairs lush, vintage voiced modulation with modern expressive control. Vibrato gives a pure modulated pitch wobble while chorus blends the dry signal for a rich doubling shimmer, and the Eddy adds envelope and expression pedal control over the rate and depth of the modulation for dynamic, playable movement. From subtle, warm chorus thickening to deep, seasick vibrato and touch responsive swells, it covers a wide modulation range. It suits players across clean rhythm, indie, surf, ambient and experimental styles who want warm analog chorus and vibrato with the expressive twist of envelope and expression control in an affordable pedal.

The Keeley Seafoam Chorus is a smooth, ethereal analog-voiced chorus and vibrato that uses an analog-digital design with an FET input to stay true to your core tone. Its True Chorus mode adds second and third voices with slight timing and pitch differences from the original signal, creating a more organic, three-dimensional chorus than typical units. Tone and blend controls are central to its range, letting players match darker humbucker or brighter single-coil guitars and push rate and depth for lush, trippy vibrato textures. The circuit pairs an uncommon IC with an opto-isolator LFO to deliver wide, shimmering modulation while suppressing the hum and noise common to analog choruses. It suits clean ambient, pop, and dreamy lead tones.
