MXL 990 Mod

I got a good deal on a cheap Chinese mic and upgraded using parts and a new capsule from Microphone Parts.  The capsule is an RK-47.  The mod went super quickly and I'm really happy with the results.  Matt at Microphone Parts is super easy to work with and I received the parts 2 days afer I placed my order. 

First some photos:

 I am eventually going to do a head-to-head with a stock MXL 990, but for now, here is a clip of me playing my bass recorded by the modded mic followed by Paul Chambers playing through what I assume is a tube U-47, just for comparison.  By the way, the drummer on my chorus is Billy Jones and on PC's it's Roy Haynes.
