I've got this good 'nuff Ibanez GSR200 bass that I found at a Goodwill a few months back. Solid bass overall, good construction, passive electronics, and it was quite a steal at $75. But the only thing that I think could be better are the pickups. I'm thinking of swapping out my p-bass pickup for a Seymour Duncan Quarter Pounder, and maybe my j-bass pickup for a DiMarzio Ultra Jazz. I've listened to samples of both, and they sound great by themselves, but alas I can't find a recording of them both on the same instrument. I know it's not normal to use different brands of pickups, but quite honestly I love the look of the cream DiMarzio pickup with the Quarter Pounder. Has anyone ever tried this combination or have any experience in this field?
