Most of the ones I admire have already been mentioned, so here's my post for this thread:
Gaye Advert - I like the way she thumps
Jah Wobble - Maybe Sid sucked, but this guy really complemented Rotten's anger and weirdness
Kim Gordon - ear splitting bass
Mark Cunningham - No Wave at it's highest potential(IMO)
And going to extremes, I think Justin Pearson really does wacky stuff in all of his bands

Hmm, a lot of American "great punk bassists" on this thread. Still, why not? The bass guitar was an American invention (even if punk wasn't
).
