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.

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The Keeley Seafoam+ is a chorus and vibrato pedal from Keeley Electronics (Edmond, Oklahoma), delivering vintage analog-style chorus and vibrato with lush, transparent modulation and a Vibrato/Chorus mode switch. The Seafoam+ provides musical chorus from subtle shimmer through deep, lush modulation for clean, ambient, and classic rock guitar at Keeley Oklahoma boutique quality.
The MXR CSP-026 Handwired Vintage '74 Phase 90 is a hand-wired recreation of the earliest script-logo Phase 90, built to the original 1974 specifications and components rather than the later block-logo circuit. It delivers the same warm, rich, single-knob phasing the Phase 90 is famous for, with a musical four-stage sweep that ranges from a subtle shimmer to a fast, swooshing warble, but with the specific vintage voicing collectors and players associate with the earliest script-era units. It suits players and collectors wanting the exact vintage script Phase 90 character in a reliable, currently-produced reissue rather than searching for an original.
