I believe the Super 58 Custom pickups are made in China, the Super 58's are the ones in the higher end models. You can also search through the threads on the Jazz guitar forum at jazzguitar.be, which I believe will get you more insight into the two models than you would get from Ibanezcollectors (I frequent both myself). Me personally, I would go with the GB10 all day every day, and twice on Sundays ( if I couldn't get a PM120)
