In the us, you can buy mxl 603/991 for $30 really easily. I ended up with 6 or 7 of them and did the “gus” mods that were popular years ago. All of the capsules are different, and some of them are much better than others.
The gus mod sounds pretty good. The km84 pcb with a cinemag sounds noticeably better.
I ordered 4 capsules from 3u audio, and those sound way better! In fact, a head to head comparison with my real km84 revealed that on some sources they were indistinguishable, and on others they had a different flavor, but were still really good sounding.
I’ve been using the 603 with graeme’s boards, cinemag transformer and 3 u capsule on toms and acoustic guitars, and they are really awesome on both. On toms I love how the leakage is natural and not that crappy dynamic kind of annoying leakage you have to worry about.
I think they're a match, no modification needed. (Not entirely sure, but one of Banzai's posts in the Lulu thread seems to indicate that the threads are a Chinese standard shared between MXL, 3U, Lulu, and several other brand rebadges.)What did you have to do to the 603 to get the 3U capsules to work?
Thank you, thank you, thank you!!! A thousand times.
To Graeme for this project.
I got two of his PCB's and built them during the second lock down in Europe.
I could not source all the parts I wanted, so I had to improvise with parts I could find. But the two mics sounded very very good to me. I used two APEX 180 as donors, slightly different insides to the MXL 603, but with a file and a bit of patience Graeme's PCB's fitted just fine.
The result was day and night compared to the originals.
I have been recording a Kiwi (New-Zelander) artist, John McClean in London over the past month & the MXL 603-KM-84's have been used over Guitars, Percs, Drums O.H. and even SNARE!!! (more on that a bit later).
And yes I had to compare with a pair of Neumann's and other SDC's we had in studio.
Result, Graeme's versions of the MXL603 KM-84 won (to my ears) most of the time.
I'm a very satisfied sound engineer/musician with these.
