I'm a big Priest fan, even more so since I had the honor of attending one of the shows on their Epitaph tour (whooooo!). I've never really thought about their bass style a lot, and can't find much on Ian Hill.

Any info on his style, sound, or anything about him really would be appreciated!

He plays a Spector Ian Hill Signature model:

I believe he also has a five-string version of his Signature bass. I know he usually plays through SWR amplifiers and cabinets; IIRC he uses their enormous 1500-watt model. He used to play through Fender Jazz Basses, but has been with Spector for a while now
