DM-2 Delay

The DM-2 launched in 1981 as Boss's first analog delay, using MN3005 bucket-brigade chips to create warm, dark repeats that degrade naturally with each repetition. It ran for only three years before the digital DD-2 replaced it, making original units scarce and expensive.

Maximum delay time of 300ms, which was typical for BBD delays of the era. The repeats roll off high frequencies with each repetition, creating a warm trail that sits behind the dry signal rather than competing with it. At just 5mA current draw, a single 9V battery lasted effectively forever.

Three controls: Repeat Rate (delay time), Echo (wet/dry mix), and Intensity (feedback). Simple and musical. The DM-2's warmth comes from the analog signal path: the BBD chip, the companding noise reduction, and the clock filtering all contribute to the character.
