The Seafoam Plus Chorus will forever change the way you think about chorus. Keeley has 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.

In the Seafoam Plus Chorus you get the automatic doubler that Keeley developed in the revolutionary 30ms Double Tracker. The ADT chorus is what Keeley calls True Chorus, because it creates a second and third voice, similar to singers in a choir. Not only do they sing at different times, they sing at different pitches.

Seafoam Mode: lush, wide and very musical. It gives you the lush sounds and tone of a vintage BBD analog chorus unit. This is where you’ll find a typical chorus feature. The Seafoam Mode of the pedal has an LFO, the regularly cycling part you hear in most every other chorus unit. It provides a classic tone that you expect and which has become part of many classic tunes. Set the rate for slow and the depth for wide, and enjoy a really spacious sounding chorus. Roll the Mix Control all of the way up for Vibrato. With the Space control acting as a Tone Control in this mode, you can go from bright to vintage warmth, dialing in the perfect chorus.

Dual Chorus Mode: Keeley created a frequency crossover-based dual-chorus engine. Imagine a dividing line that is centered on your high E-string. Control the depth of chorus independently for highs and lows. Craft the ultimate “Come As You Are” Nirvana of chorus tones. Create a very deep, throbbing chorus on the low end, and a near perfect calm on the top end. Or make the high end and shimmer and waver while keeping the low end fixed.

OK, it goes twice as deep. The Seafoam Plus Chorus is a Bass Chorus, Flanger and Tremolo too. Pop off the back, flick a switch and it’s a bass guitar player’s dream. The Space Controls gives you controls or Regeneration, High-pass filtering to keep things tight, and a haunting Tremolo you have to hear to believe.

Vintage at Heart
Want a softer tone? Chorus that’s silky smooth and warm? No problem. Internal switching puts it in “Vintage Mode.” The Keeley Seafoam Plus Chorus ships in “Modern Mode” for ultra wide, lush, and high-fidelity chorus. Either way, enjoy sounds that are downright frighteningly good. Makes you wonder, “Is that my fingers playing that tone?”
