Sounds like they had time of musical chairs model names! Lots of companies have done stuff like that. It is no biggie for those that are just getting into a brand, but for those that have been following for a bit, those waters get way muddy.
Ibanez and their 58 pickups just got odd. They had, of course, the Super 58's from the MIJ only days. Then later came the Custom 58's which often noted as Super 58's even on the website! Then they went with Super 58 Customs again often just referring to them as Super 58's. AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
