Pigtronix Attack Sustain Polyphonic Amplitude Synth ASDR


Sold out.

 The Pigtronix ASDR Attack Sustain is a polyphonic amplitude synth with high speed optical compression, infinite sustain, harmonic distortion, volume swells, tape reverse emulation and intelligent tremolo.

The Attack Sustain features a unique compression and sustain architecture with synthesizer style amplitude shaping capabilities. When the Attack and Decay functions are switched off, the pedal provides punchy yet smooth compression that allows your instrument to sustain as long as you could want.

The Attack and Decay functions have a wide range of swell and fade times enabling a palette of effects that range from cello and trumpet to tape reverse and toy piano. With short attack and decay settings, the auto reset allows you to create pulsating tremolo and staccato stutter effects.

The Attack Sustain is a far reaching evolution of the sought after, Electro Harmonix Attack Decay. For lovers of the Boss Slow Gear, Ebow and/or Fernandes Sustainer pickup, this is the ultimate pedal. In keeping with the tradition of the Attack Decay, we’ve included our own twist on the “Harmonics” control, which adds a layer of sweet distortion, as well as a HIGH-BOOST switch that adds clarity, presence and natural overtones.

The BLEND control allows you to mix in a clean sound for super transparent compression when combined with the Sustainer mode and for undulating volume swells when using the ATTACK and DECAY functions. The VOLUME control allows you to boost the effect’s signal level significantly above unity gain, even with guitars that use hot active pickups.

The Attack Sustain is an interactive pedal that relies on the player’s touch to determine when the attack and / or decay cycle will begin.

The TRIGGER input jack allows the touch sensitive Attack and Decay functions to be controlled by an external source such as a band mate or drum track. This side chaining technique results in some exceptionally bizarre and cool interactions between the rhythm of the trigger source and the amplitude of your instrument.

Designed in conjunction with effects guru Howard “Mick” Davis, the Attack Sustain is a 100% analog design that can mimic bowed string, horn and synthesizer textures without altering the essential “tone” of your instrument.
