I went with the AMI Tab-Funkenwerk T12 transformer and the CK12-Style Edge-Terminated capsule in my 990 and what a huge difference it made! I did some before and after recordings and really liked the results. I can confidently say this is the best mic that I own and would highly recommend.

Bob and Rock Science created a wonderful new microphone for me, that Bob had already built for himself, from the donor body of a MXL 910 LDC mic. Bob and I discussed our options, I came up with a few mics that I could envision myself using and we started with the one Bob had

I reached out to Rock Science and Bob about modding my MXL 4000 as I saw the project on the website. I couldn't be more pleased or satisfied with both the work and the correspondence! The communication throughout the process was stellar! After hearing the modded mic, I was so impressed with the improved sound,

Bob was great to work with right from the start! He walked me through step by step and showed me photos of the process. Most of all, the mic sounds truly amazing and now in full rotation in my studio!!! Don't hesitate if you are thinking of doing a mic mod...Bob D does awesome work!

High quality materials + good workmanship = high quality performance. It’s that simple. I love the concept of transforming these plebeian tools into something wonderful, and Bob has excellent taste. This MXL 2001 now has a C12 capsule and an AMI transformer and has become my current favorite for recording difficult-to-capture acoustic guitars, like rosewood

I didn't get into music production so I could sound like everybody else, and that attitude has influenced how I have populated my mic cabinet. I could walk into any well stocked retail music store and grab all the mics everyone else has....but what fun is THAT? I'd much rather have Bob build or mod

I really was just trying to make my mic usable. I was not expecting it to be the go-to that it has become. Thank you so much! I knew there was some reason that I plunked down good money on those "Labor Day Specials" so many years ago.

AKG C414, Rockscience 990: they sound so similar. 990 before vs after? Night and day difference. I recorded a before and after comparison and the the response was much more even and flat compared to before with a much better low frequency response. This mic was recording down past 20hz at flat response levels. It

I had an mxl 550 modified and what a difference from the original factory version more open , more clarity, its like taking a blanket off the speakers when comparing the factory to the modified version . If you have some low end sounding mics and want them to sound much better reach out to

I had two Sterling mics upgraded and they are a huge upgrade from the original product. I highly recommend anyone getting an upgrade from Rockscience.

I had a Rode NT-2 from the mid 90s that I hadn't used since probably the late 90s, as it was WAY too bright. I contacted Bob, and although he hadn't converted an NT-2 before, he was willing to check it out. I sent it to him and he found that it was a high

Yes, I could have just purchased a higher quality mic. I already have several in my locker now, my goal was to take one of my first inexpensive mics that I had ever purchased and see what the outcome may be. If you’re at all considering doing the same, do it! Hey it’s no $10k

Bob will transform your MXL990 from a meh mic into an outstanding mic. Great for vocals, acoustic and electric guitars. Loved my first one so much, I picked up another one !!! Bob does things the right way !

I’ve had my 990 rebuilds for a few weeks now and used them on vocals, drum overheads, and a baby grand piano. Honestly, they have been a pleasant surprise after spending 15 years on a shelf. As overheads, they handled the high spl really well and were nice and balanced and smooth on the top

I was using a Focusrite mic to record my vocals, which I really liked but I was getting too much high-end and this made my voice sound a little thin. I was searching around for a solution and found RockScience. They were able to take my favorite mic and rebuild it using the same casing.

I really love this microphone now. My MXL 440 has been sitting in a box for almost 20 years & I have never touched it. Since getting the mod, I have used it on vocals, acoustic/electric guitar, vocals & even a sarangi. I have used it more in the last month or two since this

The MXL 550 & 551 mics were a quick and dirty purchase I made years ago thinking maybe, even if they were cheap, they might sound good. I used them occasionally but for a cheap price, you get a cheap sound. But, when I heard about RockScience's mic rebuilds I jumped right in. Turnaround was
