A Classic Electro-Harmonix Revisited: The "Tape Reverse Simulator" Spirit
In the world of vintage pedals, the Attack Decay holds a unique place. Around 1980, Electro-Harmonix introduced an effect with an evocative name, initially presented as a "Tape Reverse Simulator": the idea is not to literally reverse your signal like tape but to recreate the sensation of sound "arriving backwards" through a volume envelope. The result: softened attacks, gradual swells, artificially shortened notes, and that "pulled" phrasing impression instantly reminiscent of bowing techniques or studio sounds.The current version of the Electro-Harmonix Attack Decay retains this creative grain and very "EHX" identity while bringing it into a more practical logic: memory, external control, and an effects loop to integrate your other pedals right into the heart of the envelope. A reinterpretation designed for today's musicians without losing the experimental charm that made the original model famous.
For Which Guitarists (and Contexts)?
The Attack Decay is aimed at musicians who want to go beyond the traditional overdrive/delay combo and introduce a sound-shaping tool. In practice, it can be both a "signature" pedal and a subtle ingredient in a mix: it excels when seeking swells without a volume pedal, arpeggios that open progressively, or notes that cut off sharply to create pseudo-staccato rhythms.Style-wise, it naturally fits in ambient, post-rock, shoegaze, film music, but also alternative rock and modern pop whenever a more "orchestral" guitar is desired. In the studio, it allows building very clean and consistent layers (especially in Poly mode). Live, it becomes an arrangement pedal: a simple sustained chord can turn into a hypnotic swell without changing right-hand technique.

No doubt this pedal is great, as I still haven't received it, I can only assume. On the other hand, concerning WB, I don't suppose anymore, it's obvious, I'm really extremely disappointed. Order placed first thing on Monday (item in stock - ordered before 12 noon sent the same day), the following Friday, the order is still\ "in preparation\â on my WB account, and I receive a message from the Post Office announcing the delivery of the package for Monday (a week exactly after placing the order!!! ), it's better to laugh about it... I can't imagine if the site was in Germany. Amateurism and/or lack of respect, call it what you want, the result is the same. Absolutely to avoid. Goodbye WB.

Questions frequently asked
Does the Electro-Harmonix Attack Decay allow swells without a volume pedal?
The adjustable attack and decay times shape the volume envelope to eliminate the natural pick attack. This enables gradual violin-like swells and short fades.
What is the difference between Mono and Poly modes?
In Mono mode, a single envelope is active and resets with each new note. Poly mode assigns a dedicated envelope to each played note, preserving the evolution of chords.
Can external effects be used in the Attack Decay's effects loop?
A built-in effects loop allows inserting modulation, delay, or reverb within the volume envelope. External processing then responds to the programmed attack and decay.
Does the pedal have built-in fuzz and presets?
The Harmonix fuzz section features dedicated controls to thicken or saturate the signal. Up to three presets can be saved and recalled.
What power supply is required for this pedal?
The supplied power adapter is an EHX 9.6 V DC at 200 mA. The stated current draw is 150 mA at 9 V DC, and the unit measures 102 x 121 x 58 mm.
