Phoenix, or Dave Farell, of Linkin Park. I love his Stingrays. And no not the animal.
Geddy Lee of Rush. Has his own custom Fender Jazz basses, I've played one before. It was awesome
I have no idea if David Ellefson of Megadeth uses any other basses. He uses his own custom Jackson basses. Played a couple Jackson basses, I think the JS2 and 3. Wanna play the Ellefsons
And finally Twiggy Ramirez, or Jeordie White, of Marilyn Manson. When he was the bassist he mainly used Gibson Thunderbirds. Not sure if this is true, but I read that the Epi Goth bass was made for him. He'd obviously use a Gibson version of course.
