This is a hardware transient shaper that allows you to modify the attack and sustain characteristics of a sound, accelerating or decelerating transients, and extending or shortening sustain. I am selling this to organize my equipment. Operation and sound output have been confirmed (visual and auditory check only). The urethane coating on the knobs has almost completely hydrolyzed, and there is no stickiness, with the surface mostly dried. A non-genuine AC cable (3P to 2P & earth) is included. ◇Please note that there may be scratches and stains that are not visible in the photos. ◇No claims or returns accepted.
