Introducing Keeley's all new Seafoam Plus Chorus - True Chorus and ADT with Reverb. It will forever change the way you think about chorus, because Keeley have developed a new type of chorus that until now has only been available in expensive DAWs and in studios. Not only is it tuned for guitar, but there are voices and modes created specifically for bass players including flanging and tremolo. Lastly, this tri-mode chorus pedal offers internal switching for vintage and modern tones, further doubling the amount of sounds you can get.
