I can answer some of that....Fender licensed out their designs (necks and bodies) to mitey mite, wich is a replacement part brand, so say the headstockon your fender cracks off and you want a new neck and dont want to buy a new guitar, thats where you'd gat a fender licensed neck. and about the floyd rose: Floyd roses (original FRs) cost about 200 dollars, and it would be impossible for any company to put out a guitar with a FR at an affordable price so they made a cheaper version, the licensed floyd rose. And since it is one design, ibanez had to get the licensing to put out their edge, edge lo pro,trs etc. hope this helps
