The 990XF is an adaptation of an old Neumann microphone circuit, designed to fit the MXL 990. This kit replaces the entire circuit of the donor mic; the new circuit provides harmonic content, moderately high output, and low noise.

This was my first time soldering. I brought the kit to a local electronics shop to get some pointers. Plus, he said if I needed, he could finish it / fix it for me. It took me like 4 hours to complete, but I was checking and double checking every step. I’m sure I could do it I 2 hours next time. It was fun and the mic sounds great. It has really made a difference on my cheap, clanging acoustic guitar and vocals. I am going to mod my 991 next. Can’t wait!

The best mod I have purchased yet! The ultra low noise floor and detailed smooth sound makes me a believer! Can wait to try more mods!
