SM57 mod

jmpizzoferrato · Post by **jmpizzoferrato** » Fri Mar 31, 2006 7:46 am

I just did the 57 mod in the new tape op. It breathes fresh air into a mic that I could bear to use anymore. The article said "less honk" and I thought that was a great way to describe it. I havnt actually put it up to a real instrument yet though. I did it at midnight last night and just kind of talked into it and switched to a regular 57.

Everyone should do this!

The latest, #52, is out and has the article.

I will also soon take the plunge - LESS HONK, (hopefully) MORE TONK

It's 3 in the morning. I couldn't sleep, so i decided to chop up one of my 57's. I plugged it in and it has signal, but my roomate is sleeping about 8" away from me, so I don't think I'll try it out just yet. I'll run it through some tests tomorrow.

Yeah, no kidding. I did a really simple test with the mics today. I just mic'd a speaker that had comercial music playing through it. I don't know that I noticed any more low end, but it seemed a little tighter and (cliche) "punchier" to me...Almost like the dampning factor was helped out. The top end was a little more "airy" or extended like. The particular song coming through the mic'd speaker was a male vocalist. I could really notice most of the difference in that frequency range. The vocal was a little less nasally sounding through the MOD57. I noticed about the same 12dB gain loss that was mentioned earlier. I compensated by just normalizing both tracks to be sure that level wasn't the only thing I noticed different. It's a pretty cool mod. I would think it might be cool on rock vox, under snare mics and toms even. I plan to run some frequency sweep tests later today on the 2 mics.

Ok, I played around quite abit this evening and found that the mod57 at equal C weighted RMS to the SM57 exhibits about 4dB extra @50Hz and about 5-6dB lift around 7-10Khz. The mids are really almost identical as far as freqency response. I also noticed that spoken words into the mod tend to pop p's less dramaticaly. I'm not sure why that would happen, but it is a pretty big difference. The difference can be heard when setting 2 capsules really close and inverting the phase on one. The P's are still there from the SM and you also hear a lot of highs that the modded version puts out. It's a cool little thing.

Cool.

anyone try this on a 58 yet? I've got two 57s, but like 5 or 6 58s that i rarely if EVER use. It'd be nice to mod them instead!

The folks over at the lab (diy forum) are discussing the pluses and minuses of doing this. It's interesting to get a little more down and dirty with the details. If you're going to do this, I highly recommend checking this thread out.

I for one am proud to say that I love my 57's as is. I wouldn't mind trying this mod, but as some of the folks at the lab are suggesting, I think I'd rather just put a different/better transformer in there, as opposed to just taking it out.

So what issue is it in? I am wondering why I have not seen it. Did I not get the latest issue?

Feeling left out,
