I just got a Warwick Corvette Standard with passive J/J pickups and I was thinking about getting a Fender Jazz for a second bass to get the warwick sound plus the classic fender sound. I was wondering what's the main difference between the MIM's and MIA's and all those. When I went to GC, the MIA's and MIM's seemed to sound pretty much the same and the S-1 doesn't do much the sound at all IMHO. I was wondering if the MIA is worth the extra 600 or if it's better spent on maybe some pedals or a cab. Also, all the big bands that use Fenders, do they use the MIA's or custom shop ones or what, if anyone knows? Thanks.
