Looking for the Shure SM57 Modification
I searched for awhile but I can't go through 56 pages of badly named threads, does anyone have a link for this?
I can't have my signature here because it will only print.

if you're looking for an even better mod, tabfunkenwerk is making a higher quality transformer for it.

here's a post by Terry Manning over at his forum describing the mod....
andrew,
there's some audio samples here of a modded/unmodded funkenwerk 57 that j.j. blair did. he has yet to indicate which is which though:

here's a link to the thread: http://recforums.prosoundweb.com/index. ... 394/15103/Just finished my first 57 trans-x mod. It is actually pretty easy in general, but I tried a few things which I didn't know, before I started, whether they would be good ideas, or not.
Here's what I found out:
Unscrew the main body from the capsule body. Screw IN (anti-clockwise) the XLR retaining screw and pull out the XLR connector with small pliers. Cut the wires leading from the capsule towards the transformer. Cut the wires coming from the transformer to the XLR. Put the main body (NOT the capsule part, of course!) in boiling water for about 5 minutes. The glue softens, and the transformer can be pulled out (use the metal brace-holder inside with needle-nose pliers) from the body. There is some glue residue, but there is also a lot of white hard plastic gunk in there. I got most of the glue out, but just left the plastic. There will be a hole in the middle of it, and in the metal piece inside, plenty large enough for the wires. Marvel at the transformer; be amazed that you've been recording through one of these for many years. (Compare it to one inside of a U-87...also marvel that you've been recording through BOTH of them for many years!)
Now is the time to paint, if you choose to do so. Carefully cover the capsule with masking tape; first a piece (with both ends folded over for easy removal) across the top of the capsule. Then two separate pieces around the capsule circumference, exposed end piece folded, being sure to cover everything capsule-wise from any paint spray. I painted the two body pieces separated at first, with an old mic stand end and a pencil holding them up (like fingers pointing inside one end), both "planted" in the ground outside, with a plastic garbage bag underneath. This way the paint will cover even the edges which will almost disappear when screwed back together. Sprayed several coats, but I also tried to finish with a clear coat of lacquer spray. That just messed everything up (globs), and I had to sand with 400 paper and start over.
Meanwhile, make a new wire harness from leftover Mogami wire. The capsule end will say "A" on the hot wire. The ground/earth is in the centre, a black wire. The other one is...the other one (-). Solder harness to the capsule end. Thread harness through the hole in body centre, and solder to the XLR. "A" (or "+," thanks to Lance "Vertigo" for this information) to pin 2. Screw body together and put masking tape on the xlr connector, inside the cavity. Paint one or two more thin coats for overall professional finished look after it is assembled.
When dry, listen to mic.
I just did a quick voice test, but I immediately noticed increased low end. The volume was down about 10 dB or so, but that can be dealt with...anyway, how often do you have to pad a mic pre using one on snare anyway! It sounds more like an SM7 to me, which I now suspect may be the same basic mic with a better transformer.
