This is a bit embarrasing...
I started playing classical spanish guitar when I was 7 years old, having my lessons at school. Then, I moved schools to find that my new school did not do guitar lessons. I did not play guitar for a couple of years because of this, then I decided to get back in to it when I was about 11, so I got a guitar tuition book. I had only ever played with my fingers, playing single notes in the classical style. The book I had bought was a rock guitar book and was all about playing chords. I just could not do it. However, there was one page at the back about bass, and with my 11-year-old intelligence, I thought that bass was just guitar played with your fingers. I had played ith my fingers on classical spanish guitar, so I thought: "Instead of guitar, I'll play bass". I received a cheap bass for my next birthday.
I never had a teacher, I just played tabs. The first things I played were blink 182 songs, because they are so simple. (I now hate blink 182 and have realised how rubbish they are). This progressed into more interesting lines, like Nirvana's "come as you are". After a few months, my playing progressed again, into scales and funk lines.
My biggest influences starting off were the guys out of the rock bands i liked, such as Nirvana. Nowadays, my influences are Mark King, Stanley Clarke and people who play grooving, tight funk lines.
