Early on, I had a fascination with how things worked... which led to many pieces of home electronics being taken apart, and to an innate ability to quickly get to the root of a problem and fix it properly.
Also a big believer in DIY work... I've been building my own mic, instrument, and patch cables for decades. When local studios need custom wiring done / computer problems solved / or just a clever solution to an interesting problem... I'm one of the first calls.
