The Keeley Seafoam Plus Chorus redefines the chorus pedal experience, merging advanced technology with an intuitive design. It features a tri-mode chorus that includes true chorus and automatic double tracking (ADT) with added reverb. Designed for both guitarists and bass players, this pedal delivers lush, wide, and musical vibrato tones reminiscent of vintage BBD analog units. It offers versatile modes, like Dual Chorus which allows independent depth control for high and low frequencies. The pedal can also switch between modern and vintage tones, accommodating a range of preferences without losing musicality.
