About the DD-2:
The Boss DD-2 Digital Delay was first made in 1983, offering the first digital delay jammed into a stompbox. Using the same integrated circuit chip as the Roland SDE-3000, the Boss DD-2 brought long and crystal-clear digital delay to the masses. It features mono input, mono/stereo output, and up to 800ms of delay time.
