    Go with WatsonWood’s advice.

    I’ve used several old DMMs, and currently have 3; and the version you have is my favorite generation. It’s the one I use the most. It was never modified. I did the trimpot alignment myself, but I highly recommend letting Howard Davis do that for you. You will be rewarded.

    Great, thanks for good advice! The only problem is that I live in Norway… sending my pedal to the States and back again might get quite expensive. I do have some friends who are going over there this summer though.

    Do you know anyone in Europe who can do this? Preferably in Norway, but I guess that’s a longshot :)

    137 is the company number (CTS) the 7xxxx is the year and week. So if its 137 7712 its the 12th week of 1977.
    This only tells you when the pots were made by CTS, not when the pedal was made by EHX.

    I’m aware of this, but I read on this forum that only the older ehx pedals have pots with numbers on them. Is this wrong?

    As for the recalibration, will this fix the problems I mentioned?

    Thanks for the reply! The one I have is a Deluxe Memory man, 5-knob, and it looks just like today’s version (the classic chassis, not the new small one:). I checked the pots, and the serialnumbers start with 1377…. so I guess that means they’re made in the 70’s. The reason I’m asking is that I thought the ones from the 70’s and 80’s were all blue, while the reissue was black. So I’m wondering if someone knows when they switched to black color.

    Now that I’ve tested it against a reissue I’ve borrowed from a friend of mine, I actually feel a bit disappointed. I’ve heard that the old pedals are so much better. Turns out it sucks alot more tone than the reissue, and even with the feedback turned all the way up the echo dies after a couple of seconds, while the reissue keeps on echoing forever. In addition it’s really noisy, but I was prepared for that:) The only good thing about the old pedal is that it can handle alot of input level without overloading, but then again I couldn’t get it to self-oscillate no matter what I did.

    I actually like old equipment, so I’m wondering what’s wrong. Is my pedal from a bad year, eventhough it’s and original wintage thing, or is it just broken? It seems to work fine, so I wouldn’t have guessed it’s broken… but somethings not like it should.

    Added a picture of the pedal, and one of the inside.

    Long post, hope somebody bothers to read, and has a good answer:)

    I just bought a Deluxe Memory Man from a guy, who told me this is a 70’s pedal. However when I got it I was disapointed at first, because the colored field on the pedal was black, and I thougt all the old ones had blue color. The one I bought looks just like the modern dmm’s. I checked the pots, and the codes start with 1377 (can’t see the rest without taking out the circuit board). So apparently it is an old one, but I’m wondering when they began making the “black” chassis, and if there is any difference in sound quality between the blue and the black colored pedals.
