So am I.
Or rather I have pretty much given up and am just trying to find a tuner that will fit the 11/16" hole without being to big for the small RB888 headstock.
There is another current thread re: Ibanez tuners where Jworrel gave links for both Hipshot and Schaller tuners that have the same 'heart' shaped knobs and are available for 11/16th peg holes.
