At 55 I had a mid life crisis (yes, I'm going to live to 110) and bought a bass. I pretty much learned to play it by using the tabs on this site. Now I play bass in two bands and am gigging regularly all thanks to Ultimate Guitar. Thanks to all the people who take time to put up their tabs. Now I am trying to give something back by using my technical knowledge.
I am a science graduate and was a science teacher. Most of my contributions are technical and my obsession is speaker design on which I can be very geeky. It does mean I will cheerfully to answer any technical questions on speakers. PM me with questions if you want, but better still post on a forum so we can all join in.
In my twenties I did a lot of work as a sound engineer for a number of bands. I've promoted gigs and run stages at festivals, worked briefly in a recording studio and made a living for a while building and designing PA speakers. I had a gloriously mis-spent youth. I hope you enjoy yours as much
