How do the different series of Ibanez compare? I know J-Custom is supposed to be top of the line. Then there is J-Craft, which is synonymous with J-Custom? Then there is the Prestige line, which is the lowest end of Fujigen guitars, but still pretty good. Is there really much difference in fit and finish? How do J-Customs of 2017 compare to J-custom models from say, 1997? What about Prestige models from that era?
