Is that even remotely compatible?

Not without fitting the capsule into a compatible CMV bayonet mount adapter.
Just wondering if anyone has ever tried it.
I have been considering a Microtech Gefell CMV563/M7s (reissue) and as I have a Tim Campbell CT12 capsule I was toying of the idea of being able to interchange the M7 with the CT12 on the CMV body.
The reissue CMV563 is using an EF86 tube.
It may simply not work sonically or it could be excellent and give me two different sonic signatures using the one mic.

I have done this a few times. A swedish customer I have has a pair of them and is crazy about them. He claims they sound better than his M7's on that preamp.

Over at the purple lounge, some years ago, when I asked a question like this I was met with pages of 'facts' and opinions about why it wasn't possible. |

Funny, when you realize it's the whole concept behind the Blue Bottle, Korby Kat & Lawson! But we would those facts matter in a purple world! |

The hard part is finding bayonet headbaskets cheap enough. He found 2 broken M8's that I installed them in.
I've tried to convince Flea to do it since they make that headbasket but they don't think anyone would be interested.

I've tried to convince Flea to do it since they make that headbasket but they don't think anyone would be interested. Vintage CMV's, and especially the bayonet mount capsules, seem to be steadily rising in price. At the moment I'm in two minds whether to build a mic from scratch using your CT12 capsule or buy a new Gefell CMV 563/M7s and find a way to adapt the CT12 for use on the Gefell. Being able to switch between a M7 and CK12 style capsule on the one mic does have an attraction providing the sound of the CT12 is not negatively compromised. Of course we are talking an EF86 and different transformer in the re-issued CMV as opposed to an AKG C12 or ELA M251 so the end result maybe somewhat of a gamble. |

I have not heard this conversion personally and am only going by my customer's opinion. The modern CMV is a superior mic, really a M92.1 with changeable capsules.
You'd have to listen to the CMV and imagine if less mids, more open, smooth top would be worth the expense and trouble. You might consider building the DIY U67 using this capsule (which would be close) or just go with it's strengths and build a C12/251.

FWIW, I have a new CMV and find it's uses fairly limited; it's very middly (in a good way) with very reduced tops so most times it doesn't work on vocals but it's good on particular instruments like accordian which is not why I bought it really. The late Oliver Archut made mention of this trait in modern Gefell m7s (reduced tops) and also how the amp was compromised to meet CE standards ( that can be reversed apparently)
I've been talking to Shannon about modding it but still thinking about that. It certainly says quality but not in a useably broad enough way, particularly given the money I paid so would be interested in knowing how far it could be taken particularly with Tim's cap.
As it is it's very pricey to get used only now and again.
Hope this helps.
Cheers. Ross

My experience is that all pre 80s German LDCs are "middly". I would venture if one grabbed randomly for purple badges in Blackbirds closet and hung them all together.....they would make the Sm7 be blindly described as "the bright one".

My 'go to' accordion mic tends to be an AEA R84 ribbon which I'm quite happy with. I have briefly tried the new CMV and it is very smooth but, as you say, not bright. This maybe due to the thicker PVC used in the M7 capsule which more closely replicates the original M7. To be frank if it wasn't for the CMV's interchangeable capsules, I would probably pick a Flea 49 over the CMV as I could imagine it would be a little more versatile. In the meantime I'm trying to decide how to best utilise the CT12 capsule. |

Or DIY Danny's M49 board buy a Lawson body and a couple of head baskets m7 c12 heck add a k47 and see what Shannon can whip up with 67 flavor without an EQ circuit ( I think The Korby was jus a capsule but Shannon would know 😀! Bet it would run less than the flea! |

Flea 49 !
Actually tried the CMV and a Flea 49 Next and the CMV was significantly better on my voice, to my ears. Smoother with less sibilance.
Using it in my studio is where all is revealed of course and horror of horrors, it's nowhere near as versatile vocally as a Studio Projects C3 into a BAE 1073; I also have a BeesKneez Arabella (producer series) and the C3 knocks that off in most vocal situations too - who would have thunk it?
O.T. but the BAE does something right for the C3, not saying it's world beating but it works ; would love to try a very good U 87 on that pre.
Still aiming to get the CMV firing for more vocals though.
Just my 2.5 cents
Cheers, Ross

Yeah Wiz - Alice Springs . Lots of music here at the mo and improving all the time; just no money of course ( consistent with the rest of the world!), but being challenged, learning and having fun. ( 3 out of 4 ain't bad)

I did the opposite, sort of. I put a K67 type capsule with a C12 amplifier circuit. I had to add a 1000 pF cap from tube plate to ground for the de-emphasis equalization. Anyway, it's a great sounding mic, I have two of them, sort of my workhorses.
