So I was looking at the back of this Tool bootleg I have again today, trying to figure out what bass Paul is playing. Then I recognized it: It's an Ovation Magnum!! http://www.williesguitars.com/Pages/magnumcl.html I don't have a scan of the picture handy, but that's definitely it. Soo. . . I wonder when he used this bass, and if he used it in the studio at all? This boot was recorded in 92 and 93, and his tone is great (no clue when the picture was taken, though around then definitely). He's also got SWR cabs, not Mesa/Boogie.
