Boss DM-2 Analog Delay
The Boss DM-2 was a bucket-brigade analog delay from the 1980's. The DM-2 originally employed the famous MN3005 BBD to produce between 30 - 330ms of delay. This chip was replaced with the MN3205 in the later models.
In order to produce the longer delay times of the DM-2, Boss engineers needed to limit the frequency response of the repeats. This resulted in the warm, rounded delay tones that make the pedal so famous.
Produced from June 1981 until February 1984.
Reproduced in 2014 as the DM-2w
Label - Black, Green
Font - Large, Small
While many people class the earliest MN3005 models as a far superior sounding pedal, the truth is that the switch to the MN3205 really isn't noticeable to the ear at all..
