Critic Reviews

Keeley Seafoam Chorus Review - Premier Guitar

premierguitar.com

The Keeley Seafoam Chorus impresses with its lush modulation and faux-Leslie tones, likely converting even longtime chorus skeptics. Its standout features include a versatile tone knob and blend controls, offering a range from vintage vibrato to modern chorus effects. The pedal's design allows for seamless adaptation across different guitars and styles, making it a flexible addition to any setup. However, it lacks an expression-pedal input, and some players might find the blend control's effect too subtle. Despite these minor drawbacks, the Seafoam delivers exceptional sound quality and straightforward operation, making it a worthy investment for tone enthusiasts.
