My Jackson RR3 has a lisenced FR in it now, but Can I put a Original one in it?
you probably should be able to.
i just dont know if the cutouts are the right size
Look at the blueprint and see if it will fit in your guitar. Take your trem out and measure up! http://www.warmoth.com/hardware/bridges/pdf/Original_Floyd_Rose_Diagram.pdf It probably will and I hope it does. If not, there are such things as routers
im pretty sure all the parts will fit the same
Not all licensed Floyd Roses are the same measurements as the OFR. Remember, it's the design that's under Floyd Rose patents, not the size and shape. You'll need to measure yours and compare it to the OFR.
