Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.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.
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.
