Super helpful, thank you! I literally just bought a vintage DC from a guy but he didn't know what year it was. It was a great price so I took a chance. The good news is it does appear to be vintage. I opened it up and the foam was indeed dissolved all to heck (by the way... don't try cleaning it by blowing into it or you will end up with a mouthful of 40-year-old foam!). From your video, I can tell that it has an LM 3080 VCA. It is a block logo on the front (no light, no power supply) and on the back, there is a small "MXR" in script in the bottom right-hand corner. Unfortunately, the pots are too dirty from the dissolved foam to read the year. I can only see the "MXR9471" on half of the pot. If anyone on here has any suggestions please let me know. Thanks again for making this video and doing the comparisons. To my ears, the '75 sounds the warmest. I most likely have an '80 but it still sounds better than anything I've had before.
@@bronyraur3 Yeah, that's about what I figured. I have found a few online that are block logo with the scripted "MXR" on the back in the bottom right corner. I may try and clean the crud off of the pot so I can verify. The battery thing scares me but I don't want to have it modded to add power if it will ruin it. Any thoughts on this?
I have the exact same pedal. Block logo with the CA 3080 and the script logo on the back cover. My pot codes read 1977. My advice is to keep running it on batteries, and not alkaline. Electro Harmonix sells a carbon zinc battery that reduces circuit loading by having a higher internal resistance. It produces a more vintage tone and protests your pedal. No here"s the real tip if you don't want to pay $9 for a 9volt; they sell cheap carbon zinc 9 volts at the dollar tree. I've been using them in mine for awhile now with no ill effects.
the '77 has more stereo signal than the other two, so its harder to tell if i like it because of that. But overall the compression does sound very cool from it. The '75 sounded better to me at 12 o'clock on a couple though...
I have an early block logo unit that still has the 3080, and the script logo on the back cover. Pot codes read 1977. Interestingly no foam or any sign there ever was any. Either they forgot it or it got taken out early in the life of the pedal.
I love that you did the WIL riff… I’ve been contemplating getting one of these vintage ones because of the compression board that was in Ed’s echo plex. To my ears the ‘80 had nice added grit… more so than just that distinct compression pop sound that is synonymous with the dyna comp. Which I’m running an Ed pedal conjunction only into a Seymour Duncan power stage into a 212 with green / black backs. Does the ‘80 version have the 3088 in it? There’s definitely a mid bump I’m hearing in the ‘80 version… although the ‘77 sounds good too!
The ‘75 and ‘77 sound really similar, perhaps the ‘77 has more body and warmth with the bass springs - yet has all the high end bite of the ‘75. The ‘80, the best I can describe is overall a darker sounding pedal.
Hey jake would u be interested in covering soda stereo tracks also with Gustavo ceratis solo work. I think u will like it and goes along with your style

77 all the way. Has the most color and the most jangle, really squeezes yet retains a beautiful clarity.
sounds exactly like my mini. the most transparent out of these
10K dude congrats, well deserved
Hey jake, is the lesson "stop, look and listen" by army of anyone in your program? (The acoustic version)
I like the grunt the 75 gives to low frequencies! Kinda vintage rock!

Thanks Derek, from the sound of it, your pedal is from 1978-81. If it's the LM that is.

1975 is best imo
