My parents always wanted me to have a go at everythig. They made damn sure I had the opportunity to try everything I wanted and I really respect them for that. At the age of five I started on the cello (actually I was very small as a kid so it was a converted violla). I was still playing when I got to secondry school (in the UK you start at age ten). The music department was run by a great guy called Mr Cowling who really loved anyone who was into music and wanted to give them any help he could. I played cello in the orchestra (the only one for a couple of years), but I also got to play the violin, violla, double bass, guitar, bass guitar, piano, and drums. I had lessons on all of them (I know, I should be a musical genius by now, but yet...).
Anyway, aged fourteen I really lost interest in classical music (it's coming back now though) and I started to focus on the guitar. My parents paid for private lessons and helped me buy my first guitar (I sold my bike to raise the rest. I sold it to my sister, what the heck is that about?).
I played drums, bass, and guitar in a few bands (all of them awful, though I was hardly the strongest member of any of them). I finally formed a decent band at uni (me on guitar). A couple of bands later and the drummer and I are still working together.
So, we come to the crunch moment. This was a pub conversation six months ago. The band was falling apart. I was one of two guitarists, the singer played bass (though he couldn't), and the drummer. We'd come to the conclusion that we needed a decent bassist and no-one really wanted to bring in a new member. So, after a few too many pints I pipe up with "I've played some bass, why don't I do it?". Silence, cheer, silence, and here we are.
I couldn't be happier. I'm having much more fun on bass than I ever remember having on guitar. The band sounds much better now. Partly because we can all play our instoments and partly because one guitar suits what we are doing much better than two ever did.
Sorry, long story. I checked 'other' in the poll.
Cheers
