Hi,
does anyone know where I could find a schematic for this mic?

Also, were any mods ever tried out on this mic by anyone?

Thx
 
I've never seen a schematic for one.

I think the reason it's not considered much for modding is that most people like its sound the way it is. If you were going to mod it, I think that the usual cap replacements would be first, and then maybe relaminating the transformer, though the stock one is supposed to be fairly good.

I believe Brent Casey played a part in its design (as he used to work for Marshall Electronics) and maybe could chime in on what he thinks of modding it and where a schematic might be found.

I have a couple of them - might be interesting to mod one and compare the sound - if I had a few more lifetimes.
 
It’s just the early generic Feilo FET-to-transformer (with a bipolar in the middle to help out with the impedance conversion) type circuit – same as the 2001. I suspect the part Brent played was talking MXL into using better transformer lams. Don’t know for sure, though. Otherwise, as far as I can tell, the V67 and 2001 circuit’s are identical.

There’s no voltage multiplier in this one, btw.

The thing I would recommend for the V67 is Scott Dorsey’s mod. You can buy the circuit board and FET straight from him and the rest from Digi-key. Here’s a link to some of the info: http://www.pfarrell.com/music/shanghaimic.html

I put that board in a Cascade mic I got from Bayview which uses the exact same circuit as the 2001/V67 and it sounds great.

The problem with that mod is that it makes it sound like the MXL2003, and it doesn't sound like a V67 any more. Depending on your preferences, that may or may not be a good thing. I happen to like the V67 the way it is.

I like this mic alot. Anyone know a mod to change the colour on the body.
Thx

That’s strange cause the 2003 is a completely different circuit, grille, and capsule. Not doubting Harvey’s opinion in the least, btw, but I just wouldn’t have thought that (and thanks for the insight Harvey, because I haven’t put Scott’s board in a V67 and doubt that I would want to now.)

If you like the V67 like it is, then I’d at least try the 1000 polystyrene between the capsule and FET. Should just give you a clearer, more open version of what you have.

If the truth be known, I’d say the grille design has more to do with folks liking the V67’s sound then anything else. Just MHO of course. ;)

Thanks FP,
because of you thats the first modification I think of .
Do you still get yours from mouser or do you have better/other sources now.
Thx

Strike the letter "g" and add the letter "m" ;)

Mouser's the only place I know of here, but I haven't really looked that hard. Can you not find them in Canada?

I pretty much agree - except:

Scott Dorsey's mod gets rid of the transformer, and that's a good part of what gives the V67 its unique sound. The rest (as you pointed out) is the shape of the grille and the housing.

When you apply the Dorsey mod to the 2001, it basically sounds almost identical to the 2003, to my ears, anyway. It does smooth out the high end, but it's still a little on the bright side for my tastes.

While most people think of the V67 as a kinda dark mic, I tend to think of it as not an excessively bright mic.

Thanks again for the insight. I’ve always wanted to get a V67 and drop in a circuit similar to Scott’s (actually a Schoeps circuit – same one used in the 2003 minus the voltage multiplier), but now I think I’d just do a cap upgrade. I’d probably also re-laminate the transformer with some super q’s I have lying around just to see if that makes any difference.

But OTOH, my friend Gus says they make great sounding tube mics! :D
 
v67

Hi,
parts are a little harder to get here I was more wondering about the quality of the caps and where to get them from. I tend to rely alot on other people to pin down caps that are a good bet to try. I have the time its just the money.

Thx
 
Keep us updated on these mods, guys. Interesting stuff.

No disrespect intended towards anyone here -- this is merely my personal opinion . . . but I like the idea behind the v67. It seems to be trying to sound like something. I like it's mild midrange scoop. I like the proximity boost . . . and the high end is smooth. I realize this is an overused expression, but I suppose you could say it has almost a German sound to it.

There's just this overall crappiness to the sound, for lack of a better word. Like it's almost there, but there's this cheap layer of film that needs to be removed from it. Sort of the proverbial "blanket over the monitors" kinda' thing. And the funny thing is the transformerless versions like the 2003 are just the other end of the spectrum -- like they could use a few extra layers. :D

And I don't think it's a matter of it's frequency response, either. The v67 doesn't sound "dark" to me. I don't think of it as a quote-unquote dark mic. It just sounds kind of mushy and unintelligible to me on a lot of voices. I suppose this could be a good thing on sources that may sound too forward, but I never found the ideal combo.

Just curious if anyone's tried anything that's improved it significantly in the areas I just mentioned ? ? ?
 
Personally I like the V67G as it is (stock)... and if I want a different sound I grab another mic. :)

To my ears, the V69 would be the mic you're describing. And to me, the V67 doesn't sound dark, it just has less of the hyped high end that I hear in so many mics these days.

In my original evaluation of the V67 (done several years ago), I DID say that I thought it had a "older German mic sound" to it.

That would be the caps and the transformer. Drop in a couple of good caps and a Lundahl transformer and you'll probably be in love! :D
 
>Just curious if anyone's tried anything that's improved it significantly in the areas I just mentioned?

Matthew Baker did the Dorsey mod on my V67m a couple of years ago. I liked it as a stock mic, and I like the modded version as well, but I never had the chance to compare them directly.

In my limited experience with the modded version, I'd say that it's a mic that sounds great through a Mackie 1202 VLS Pro, but through a Davisound preamp it sounds a bit raw and overly detailed.

I suspect that there's a limit to how much this microphone can be improved through modification, and maybe that's the point. For me, the Studio Projects T-3 was a clear step up from the modified V67, and the Audio Technica AT4060 was a step up from the T-3, though not as dramatically so.

Best wishes,

Mark H.
