DM-2 & DM-3 Delay pedals in the studio (left side)

thumbnails | text

Analog delay pedals by Boss. Each has 3 knobs for repeat rate, echo, and intensity, and delay adjustable from 20-330ms. The DM-2 was sold from 1981-84, and the DM-3 from 1984-88 - neither are currently produced. The DM-3 has an additional filter and high speed noise reduction circuit, as well as an extra direct output jack.

Both the DM-2 and DM-3 can be seen in a small stack of pedals from a video on Kerry Brown's blog on 2009/10/12, of Billy playing A Song For A Son on a Rhodes piano- they are the two red stomp boxes on the left.
