The Edge was known for having two Deluxe Memory Man (DMM). Nothing can compare to the organic sound of analog delay, and no one does analog like the Deluxe Memory Man! This masterpiece analog delay made his debut in 1977 replacing his older brother (the conventional Memory Man). Even on U2’s debut, 1980’s Boy, the Edge’s cascading guitar textures are in full bloom. Experience the analog edge. Up to 550 mS of vibrant echo that rivals tape delay; lush, spatial chorus and haunting vibrato are just a few of the treats in the Memory Man's sonic smorgasbord! Armed with just a Gibson Explorer and a Memory Man echo unit, the guitarist lashed out at parochial attitudes about what rock should sound like and what it could communicate.
