I have a Casio MG500 - the cool looking MIDI guitar from the 80's.

Kind of weak and rather warm for single coils with a splitable humbucker in the bridge. The trem is a standard strat style trem and the tuners function fine. Overall, it works as is. My thoughts were to replace the trem bridge with an upgraded one (that requires NO drilling or mods to the body) and replace the tuners with something a little more high-tech looking (like Schaller M6'
