Seafoam Plus Chorus – True Chorus and ADT with Reverb

Keeley Engineering is changing the minds of even the most picky players… again.

We redefined chorus. There is a new style of chorus that actually sounds RIGHT.

We are proud to announce the all new Seafoam Plus Chorus – True Chorus and ADT with Reverb. It will forever change the way you think about chorus, because we 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.

ADT: THE NEW DEFINITION OF CHORUS.  In the Seafoam Plus Chorus you get the automatic doubler that we developed in the revolutionary 30ms Double Tracker. Our ADT chorus is what we call True Chorus, because we create a second and third voice–like singers in a choir. Not only do they sing at different times, they sing at different pitches. True Chorus.

Seafoam Mode: You guessed it… the all new Seafoam Plus Chorus–lush, wide, and with a very musical vibrato. 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: We 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!

ChoralFlangelo

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!  o let’s get down and funky, Michelangelo!

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?!?”!
