My family have always supported me, no matter what instrument I picked up. They haven't inspired me due to my parents never touching an instrument, but my grandfather played piano and I guess that was always a bit of inspiration.
I guess a few years ago, I found that I'd love to play bass, this mysterious instrument that wasn't always talked about, and sometimes missed. I trained my ear slowly to listen out for the bass, turning from metal (with some barely audible stuff) to other rock, punk, funk, jazz.
In terms of inspirational bass players, Mic Todd from Coheed and Cambria is definitely one. As for others, they change in order of what music I'm currently listening to.
