Seafoam Plus Chorus – True Chorus and ADT with Reverb

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

We redefined chorus. There is a new style of chorus thatactually 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 aboutchorus, because we have developed a new type of chorus that until now has onlybeen available in expensive DAWs and in studios. Not only is it tuned for guitar, but there arevoices and modes created specifically for bass players including flanging andtremolo. Lastly, this tri-mode choruspedal offers internal switching for vintage and modern tones, further doublingthe amount of sounds you can get.

ADT: THE NEW DEFINITION OF CHORUS. In the Seafoam Plus Chorus you get theautomatic doubler that we developed in the revolutionary 30ms Double Tracker.Our ADT chorus is what we call True Chorus, because we create a second andthird 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 PlusChorus–lush, wide, and with a very musical vibrato. It gives you the lushsounds and tone of a vintage BBD analog chorus unit. This is where you’ll finda typical chorus feature. The Seafoam Mode of the pedal has an LFO, theregularly cycling part you hear in most every other chorus unit. It provides aclassic 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 spacioussounding chorus. Roll the Mix Control all of the way up for Vibrato. With theSpace control acting as a Tone Control in this mode, you can go from bright tovintage warmth, dialing in the perfect chorus.

Dual Chorus Mode: We created a frequency crossover-baseddual-chorus engine. Imagine a dividingline that is centered on your high E-string. Control the depth of chorusindependently for highs and lows. Craft the ultimate “Come As You Are” Nirvanaof chorus tones. Create a very deep, throbbing chorus on the low end, and anear perfect calm on the top end. Or make the high-end and shimmer and waverwhile keeping the low end fixed!

ChoralFlangelo

OK, it goes twice as deep. The Seafoam Plus Chorus is a BassChorus, Flanger, and Tremolo too! Pop off the back, flick a switch, and it’s abass guitar player’s dream. The Space Controls gives you controls orRegeneration, High-pass filtering to keep things tight, and a haunting Tremoloyou have to hear to believe! o let’s getdown and funky, Michelangelo!

Vintage at Heart

Want a softer tone? Chorus that’s silky smooth and warm? Noproblem. Internal switching puts it in “Vintage Mode.” The Keeley Seafoam PlusChorus ships in “Modern Mode” for ultra wide, lush, and high-fidelity chorus.Either way, enjoy sounds that are downright frighteningly good. Makes youwonder, “Is that my fingers playing that tone?!?”!
