JDD-3000

The Korg SDD-3000 rack unit shaped the sound of an era—it's the delay on The Unforgettable Fire, The Joshua Tree, and countless U2 records. Mr. Black's JDD-3000 captures that specific digital delay character in a pedalboard-friendly format: up to 850ms of pristine, interactive delay with the delicate modulation that made the original rack unit feel alive rather than sterile.

Controls for delay time, feedback, and modulation. Features a programmable preset, tap tempo input, and trailing echoes that continue on bypass—the tails spill over naturally rather than cutting dead. Clean digital delay with the musicality of vintage rack units, not the harsh artifacts of cheaper digital circuits.

Buffered bypass with trail spillover. 9VDC center-negative, 68mA. Handmade in Portland, Oregon.
