I first picked up a bass guitar at an all Wales scout camp, around 6-4 years ago (probably closer to 6), where a rock band was giving taster sessions on the instruments in a rock band, the guitarist was a show off and that put me off it and I couldn't get the grasp of drums. After that I asked my dad to get me a guitar (I had no idea what a bass was at that time, I thought I didn't like music at that stage because I didn't like what was on the radio) and he bought me a cheap acoustic. I didn't really pick it up very well, I don't know whether it was the teacher or me, but I wasn't pushed enough so I wasn't too upset when I lost the guitar a few weeks later.
A few years later, when I had discovered that all music wasn't played on the radio, and had really gotten into metal (still the more popular stuff at the time, such as dragonforce and bullet for my valentine), My gran had decided to treat us to a cruise and on the ship there was a rock school thing where we where given basic tuition and would play a song live at the end of the cruise, I had made some good friends who happened to play instruments, there was two guitarists, a keyboardist, a drummer and a singer, and we wanted to do an extra song (smells like teen spirit). This was decided at the last minute as everyone else knew the song, as I hadn't had access to a bass to learn the song, I was quickly told what frets to play and I went on stage and attempted to play it, I don't think I was too bad considering, but it wasn't great.
After that I got a bass and the rest is history.
