MD 409 in pieces
MD 409 in pieces
Hey people, been awhile. Life and stuff. Anywho, I have 2 MD409s that I got a great deal on a while back, but they are literally falling apart. I want to put the capsules in a new home - I guess theoretically I could put them into a 609 body, but I'd rather they have some vibe. What say you good tapepop folks?

You could, if the capsules are in excellent shape.
Howling at the neighbors. Hoping they have more mic cables.

Re: MD 409 in pieces
509 or 609 works. also grundig gdsm 200 is the same mic as well. 509 409 and grundig all have the same capsules i believe. 609 has a different capsule.
i think the 409 is the best mic for guitar amps, what a mic! when i toured our FOH guy had a couple 409 that he swore by, those guitars sounded great. when we'd have a flyout and it was some sm57 on there it wasn't the same.

Re: MD 409 in pieces
Just to clarify, the capsules sound fantastic but the mic bodies are falling apart. What would y'all do, snip the wires and into a 609 body? Anybody out there with unrepairable 409s that wants to make a few bucks?

Re: MD 409 in pieces
Yep. But you might want to also salvage the circuit too, if possible.
The capsule is but one component of the whole picture.

Re: MD 409 in pieces
Hm. I never inspected inside the stem part, but it seems like it's just the capsule wired to an XLR connector. Are you speaking from experience? See here, although I haven't researched the source yet:

Re: MD 409 in pieces
Never had to open one up... but, if it has electronics, they would be worth replicating / salvaging.

Re: MD 409 in pieces
pretty sure the MD409 has a transformer output.
A friend had one he carried around for Saxophone duty. Best sounding sax mic I've heard. Of course he was a great player too so maybe any mic would sound good on him...

great on trumpet as well. just a f'ing great mic all around!digitaldrummer wrote: ↑Fri Sep 13, 2019 7:01 ampretty sure the MD409 has a transformer output.

Re: MD 409 in pieces
Yeah, always loved this mic. Also on toms. LCD soundsystem uses them on vox. Pretty much anything you'd put a dynamic on, although I never tried inside a kick. Hmmm....
Will post pics soon. If I remember.

Re: MD 409 in pieces
Some pics. Seems like the capsule is wired straight to the XLR.

Re: MD 409 in pieces
It's possible there's a small transformer before the XLR. It might be worth trying to get the base apart to check(carefully, of course.) Or if you have an ohm meter, check for resistance between the leads that go down to the XLR. If you see resistance (usually something under 1K, sometimes way under), then there's a transformer in there. There are mics (some of the EVs for instance) that have a sort of all-in-one diaphragm/transformer setup--could be that you have something like that here. I've never owned or been inside a 409, so I don't have any firsthand knowledge on that.

Re: MD 409 in pieces
There most likely is some circuitry inside the chrome capsule housing.
Which is good, saves you from having to recreate it, just wire it into another housing.
You may want to try to contact a few mic repair people, and see if they have a spare body laying about.
