I'm looking at getting a MIM Jazz bass soon, probably a deluxe with the active pups. As we all know, every guitar you pick up is a bit different from the other. It's almost like they have their own personalities. Anyway, can those of you who are j-bass experienced give me ideas as to what to look out for as I make my selection. For instance, are there common faults to look out for? Any little tests I should put the bass through before buying? This is only my second bass, so any info would be appreciated. TIA!
