I can be a very violent player - no I don't whack old ladies over the head with my bass and steal their scone money - I have a tendency to whack the strings and stuff and I simply couldn't do that on a guitar
I've tried picking up the guitar but cannot get past the fact that they feel so small and sound so screetchy, not to mention those tiny strings.
In a band context, my experience is that after keyboard players, a good bass player is almost as hard to find. I could never have become as good as I am by jumping from instrument to instrument.
A bass feels like home to me. It feels like the most natural thing in the world as I have now been playing over twice as long as I haven't ( I started when I was 11 and am now 34)
