I started on key type thingys too!
When I was 4 (well 2 weeks away from being 5, as it was Xmas), I got one of those mouth keyboard things & played it constantly. My folks got me a Bontempi organ the following year & over the early years I had a few different keyboards & started getting into synths.
When I was 12, I went to a local music shop to buy a monosynth (Jem SX1000) & my brother bought an acoustic guitar (just a cheapo no name, but this was my step into stringy thingies). After a couple of months he decided the guitar wasn't for him & gave it to me. I found I mainly played basslines on it, though I did learn to play chords fairly quickly on it.
After a couple of years (aged 14) I decided to buy myself a bass to see if I liked it. I got a Vox Standard (which I still have, though it's in bits), that was 1985!
After much playing of synths I kept going back to the bass, so in 1990 I bought my Ibanez SR1000 & also got an Ibanez Artist guitar from a friend.
& that's me. I now have no synths (for the past 15 or so years) & after much chopping & changing, I still have the same bass, but the guitar is now a Freshman CE300 Electro Acoustic.
