The Attack Decay Tape Reverse Simulator from Electro-Harmonix is well-known for producing volume with reverse swells, backward tape sounds, artificially short staccato notes and bowed instrument effects. Originally released digitally, this new model gives players an envelope of effects in a simplified and compact package. The Pico Attack Decay allows you to dial in your sound in Mono mode—one volume envelope for all notes—and the revolutionary Poly mode, where each note has its own volume envelope to create cascading swell effects and leads with agile attack smoothing. With intuitive functionality and easy-to-use controls, the Pico Attack Decay opens up creative avenues for any player interested in pushing their sound.
