Oh dear, here goes....
Male, 43, been "playing" since I was 16. Originally inspired by John McCoy who, when I was 16, I thought had the most amazing, thumping, roadworks sound. He was 20-stone of sheer entertainment! I started playing with a pick, but quickly moved to fingerstyle as I found I could play a helluva lot quicker that way. Never been able to do the slap/pop thing.
Currently got a 4-string and a 5-string and love 'em both. Never gigged or even jammed. I just play along with tracks - anything from Pink Floyd, Rush, Queensryche, to AC/DC, Deep Purple, Bryan Adams, blues, and loads in between. Used to just play along with vinyl records with the bass on the stereo turned down. Now I use Adobe Audition to filter out the bass part leaving everything else mostly untouched. I plop the modified tracks into a cheapo MP3 player and that goes through a little mixing desk with my bass so I can play along. I try to improvise a bit too (in the case of Rush I improvise quite a lot - usually improvising root notes!). Currently teaching myself to read notation; it's a slow painful process, but I'm getting there!
