Description
The original Attack Decay from circa 1980 became legend among tone chasers for one reason: it could make a guitar sound like it was playing backwards. By shaping the volume envelope of your signal rather than its EQ or gain staging, it fakes reversed tape swells, cello-like bowing, and choppy staccato bursts that no ordinary pedal touches. EHX has rebuilt that vintage circuit from the ground up, keeping the weird magic intact while wiring in the flexibility players actually need on a modern board.
At the core are Attack and Decay controls that shape how each note fades in and swells out. Mono mode gives you one continuous envelope that resets every time you play a fresh note — closest to the original unit’s behavior. Flip to Poly mode and every note gets its own independent envelope, letting chords and legato runs bloom and decay individually rather than as a single blob. A built-in Harmonix fuzz, now with dedicated gain, tone, and volume knobs, layers distortion into the envelope for grittier bowed-instrument and swell tones. An onboard effects loop lets you route the Return signal through your own pedals before the envelope gets applied, opening the door to filtered swells, reverb-soaked reversals, or modulated bow effects.
Expression pedal or CV input puts real-time control over every parameter within reach, and three onboard presets mean you can recall your favorite envelope setups mid-set without kneeling down to twist knobs.
