I struck gold, and no, she doesn't have a sister, or at least a single one...
Over the years she's gotten me some incredible gear gifts. She knew someone at Eventide, for instance, and scored me a fully loaded Harmonizer for about 1/2 price. When I had an ADAT studio, she bought me a BRC. And there's been more...
We met at a club on New Years Eve when she came up to me after I finished playing and asked if I needed any help wrapping cables!
The cool thing is, she LIKES gear as much as I do, and encourages me to buy more! She's a theatrical director, and uses my studio (for free, of course) for all her sound cues and effects in her shows.
A couple of years ago, after years of not being able to flush the toilet while I'm tracking, etc. she bought a little cottage right on the ocean only 12 miles from my studio. That gave us an excuse to buy a boat. So now, we both have a place to get away from the studio, and i actually have a life outside of music.
In addition, between her and my dog, I think that's half the reason i get repeat business. She's equal parts smart, funny, and statuesque. (That would be the girlfriend, not the dog).
