"Electronics has been my hobby and passion since 1980. I have rebuilt, repaired and made custom guitar amps. In 2003 
I turned My interest to microphones. I started because I wanted to record with better microphones.The best vocal mic I
had at that time was an AKG C414EB with a teflon capsule. I saw on the internet that David Royer was modding
MXL 2001 mics. I sourced the parts and attempted to build my first microphone. It took a while to get the mic to work,
however when I finally got it to work, I was hooked! I experimented with different tubes, resistor values, and I read all that I could find on the internet and studied any schematic I could find. I started to experiment with changing components in stock microphones and found many changes that improved the sound of the microphone. I rebuilt and modded any mic I could get my hands on."
