Electro-Voice RE20 Microphone Repair

- The Electro-Voice RE20 is a legendary dynamic (moving coil) microphone used in broadcast and studio recording environments all over the world.
With age they suffer a number of issues due to materials or glues in the mic disintegrating. Inside the mic we repair today, the foam that keeps everything in place has dried out and turned to dust, so we are gonna re stuff it. Its a straight forward fix but microphones tend to be delicate, lots of small parts and fiddly, not to mention expensive.

Thank you I’ll look around. And thanks for you quick response and also your video 👍😁
Can i see what screw driver did you use to open ?
Hello, I have one of these and suddenly it lost the bass, the sound comes out with a medium bass
To unscrew the bottom 1/8th Hex was too small. I used 9/64 Hex 1:42
I could have got that wrong, more used to metric lol
Great job with the foam replacement on the re20. The new version have same foam inside or just the older versions? Very detailed step by step process in the video.
Thanks! To be honest im not sure, very common issue with many foam things from 40 odd years ago, so hopefully just a retro foam issue and newer foam(s) are made from compounds that don't turn into sticky crumbs
I just bought an RE20 after having recorded vocals with an sm7b for over a decade now. What's your opinion on using an extra windscreen on top of the already built-in one?
Sorry late reply! in most scenarios prob not needed
Is the RE-20 as rugged as the Shure mics like sm57, sm58.. Do you think it can hold up for years without breaking? I understand it depends on how well you take care of it but that internal foam seems to be a bummer
I doubt you could throw one about as much as an shure sm, they are however more intended for studio use and a better sounding mic. I think the more modern RE20s prob use better foam or a different construction. The one in this video is I think an early 70s mic and for whatever reason foam from this era doesn't seam to last, seen it disintegrate on all kinds of vintage equipment!
@@bonzomusik thanks for your response..best takeaway is 'it's a studio mic'.i love your slow paced, step by step video.. really helpful.
@@joshmcdzz6925 thanks, glad it was helpful
Is there a trustworthy mic service repair/restoration company you can recommend to do a foam replacement on these?
If your in the UK, I've used funky junk in the past to service some vintage nuemann mics
Hey Brah, do you know where a chap might be able to purchase parts for an RE 20 the drummer dropped one and it now has a slight dent in the screen and the cover.
Thanks!!
TBH not really sure, you might be able to find a broken mic on ebay that has the parts you need
EV themselves can probably sell you one.
What kind of foam is that and where do i order it?
You can use anything really, as long as its not a dense foam, something you can almost see through, kinda thing you might find on a speaker cover. I basically used something I had kicking about from some packaging. If you don't mind spending a bit you can also get a re foam kit from ebay.
the amount of work involved just to change the foam is ridiculous. After all these years, i can't believe EV or ALL mic manufacturers for that matter hasn't figured out a better way to prevent plosives or better foam to put inside the mic that doesn't disintegrate after a few years.
I have an sm7b that's only 2 1/2 - 3 years old and the foam on it is already falling apart, is all deformed and needs to be replaced already. I would cringe at the fact that if i had bought the RE20 instead, i'd already be needing to think about replacing the foam.
The foam in the re20 also holds the capsual in place, like an anti shock vibration mount, so that's also problematic! I'm not sure if the modern re20's are subject to the same issue, maybe the foam is a different compound that holds up better, the one in my video is a 1970s mic. Surprised your modern shure mic is falling apart though, that doesn't seam right.
@@bonzomusik it might be the environment that i live in. It's a bit humid where i live and that moisture in the air probably causes the foam to degrade much faster. It's at the point where if i run my finger across the foam, little flecks of black dust comes off cuz it's literally disintegrating.
I am scared to open mine 😂
The really delicate wires are on the top of the diaphragm, like size of a thin hair, other than that its a pretty robust thing.
