Yeah he's been playing Tobys for years, most of which have been modded with EMGs and diferent bridges - he has threatened to retire the though!)). He's also played Fernandes for years. Apparently a few of the guys from Tobias went on to work in the Fernandes custom shop and he had them build him a few basses. He's also used imported MTD stuff (during his Ozzy days - used to be called Grendels but can't remember the new model name), Fenders with Black Label Society, had a signature Zon 5 and played Musicman 5 strings when he moved to Metallica. His most recent addition is his custom shop Warwick 5. It's based on a Stage 1 streamer but has a Gotoh roler bridge and jazz pickups in non-Warwick positions. There's probably many more. It's quite refreshing to see a guy of Robs stature playing whatever he feels like... pity he's not getting to really show off his chops with 'tallica, although anybody who can play 'Battery' with fingers as well as he does deserves mucho respect!
