JJ Burnel from The Stranglers for me - got me enthused about playing bass when I was a 15 year old.
Then, when I was 17, seeing an amazing bass player with Jools Holland (just after he had left Squeeze). Supporting The Police at Ingliston Exhibition Centre, Edinburgh, on New Year's Eve, 1981. The bass player blew my mind - so fluid, muscular, and inventive. I thought, "now, THAT is how I want to play"!! The bass player was Pino Palladino! (incidentally, I still remember the bass he played - red Fender P-Bass, no scratchplate, small curved chrome control plate, and a Jazz pickup in the bridge position).
