The DM-2 was the first compact delay pedal ever made, launching in 1981. To get the bucket brigade chip at the centre of the design to produce a then-very-long 300ms of delay, the signal had to have the frequency response limited, resulting in the warm, gooey, full and natural tone these pedals are so sought after for. All other analog delays are measured against this pedal, it certainly spawned generations of imitators. This one has a few knocks but is looking pretty good for forty years old.
