I found my very long lost MXR Distortion +

    I thought it long lost or traded away. Probably my first pedal from long ago. I probably I bought it to go with my Fender Champ, but can't be certain. Anyway the foam was all rotted, I blew it out, but not sure how to safely clean it.

    It functions. The one knob is pushed in. Not sure what to do with it, probably clean it up and trade it, probably worth sumpthin'.

    Wow that’s way cool! Looks like late 70’s/early 80’s with the mustard yellow and block logo.

    I love the earlier MXR D+ pedals. I have a ‘77 Mustard yellow Script Logo D+ and it’s an incredible pedal. The gain is so warm and rich—nothing like the Banana colored D+ circuits of today!

    Mine is a 77 or 78 block logo. They’re such fantastic pedals.

    If the threads aren't damaged too badly on that pot, you might be able to unscrew it, push it back up, and tighten it down correctly.

    Nice find :thumb:

    What's a safe way to clean the foam out?

    If it was mine or someone trusted me to do the work, the first thing I'd do is take everything out so the enclosure is empty, being careful not to wack the board with any stray ESD in the process. Then I'd deal with the foam. A hard plastic scraper of any kind would probably do the job. Then I'd hit the pots with Deoxit followed by a good inspection and cleaning of the rest of it including the input/output jacks.

    And then I would look to the sky, close my eyes, and ask Randy Rhoads for good luck hoping the thing works right.

    :D

    If it works leave it as is and use it!! First dirt box I ever owned around 1981. Still a great tone..

    I have an old block D+. It was pretty beat up so I modded it with a bass boost and LED clipping options. Really useful boost/fuzzy drive.

    This tread got me to dig through some old boxes in the garage this weekend. Cleaned it up and dropped 9 volt battery in it and it works great. Most of the foam kinda just fell out. I put some 1/16" neoprene in to insulate it. This was the first pedal I ever bought...I think early 80s. IMG_0636.JPG IMG_0641.JPG

    Only one thing. I would be shocked (so to speak) if a pedal made with largely discrete components from late 70s or early was susceptible to esd.

    No good reason not to be cautious but unless you are a lightning rod and blow the legs off everything you ever touch it will be fine.

    You might as well install an 8 pin IC socket, so you can try a few different op amps. Stock one was the 741 IIRC

    Love those old school MXR pedals. I am still Jonesing for a D+. I do, however, have a 78 block logo P90 that I put an R28 switch and an LED into.

    Pretty sure this is the first pedal I ever owned. Block logo script bottom. Pots date 23 week 77. It's been used for sure. Not in awhile. I'll have to give it a go.
    Might as well add my knob-less Distortion II
