I add these to any Ibanez guitar, unless they are already installed from factory. It is a drop in replacement and makes changing strings so much easier. They are shockingly good tuners, no back slap, neither too slow or too eager. The mechanical quality is just incredible at this price. The stability is amazing - I have one Ibanez with these tuners which has a a Floyd Rose installed in place of the original edge tremolo. The locking nut on that guitar has now been removed. The strings are locked at bridge and the tuners and the stability is ridiculous. I have the freedom to use the tuners if something goes out of tune, and not the dreaded fine tuners which run out of tuning ability.
