This analog delay pedal is able to produce delay times ranging from 30 to 330 Milliseconds. It’s got three dials with adjustments for Repeat Rate, Intensity, and Echo. This effect draws a lot of current so not all power supplies are able to power up this pedal. The vintage analog DM-2 is a very popular effect and prices are usually very high for a beat up but working pedal.

Version differences 
There are at least 3 different versions of the DM-2. The first version was using the MN3005 BBD. This was soon changed to the low current version of the same circuit called MN3205. It is worth noting that the MN3005 has a SN ratio of 75 dB while the MN3205 is a little more noisy with its 67dB. The MN3205 only produces 0.8% distortion compared to 1% for the MN3005.

The DM-2 can be approximately dated by reading the number on the compander IC NE570N. It should have a 4 digit number giving you the year and month of production in the form YYMM. Note that this is the production date of the integrated chip and not of the pedal but it’s unlikely that the chips were stored for very long before used.

DM-2's are older Boss/ACA adapter requirement - so either a Boss ACA adapter, Daisy Chain, 9v battery, or 12v adapter powers it - a typical everyday 9v 200mA adapter will not be sufficient power, the light will be dim and the output distorted (in a non-desirable manner). Plenty of info available on the 'net about this little quirk the earlier Boss pedals have. THIS PEDAL HAS ALREADY BEEN CONVERTED TO 9vDC PSA SPECS

Has had some solder joint touch ups and battery clip replaced

I'm trying to avoid from instituting a no refund policy on vintage gear, so other than guaranteeing that it will not be DOA, ANY return on vintage gear is an automatic 15% restock fee. Any questions, please ask.
