IME Hipshot tuners suck
You have the right to be wrong.
I don't like open gear tuners. It's just a poor design. You want to keep debris and crap out of those gears, they should be covered. There do exist well made open gear tuners, but none of them will work better over their lifetime than similar quality closed tuners.
Just an FYI - I'm gonna replace them with the original ones. I don't care about the ones on there now.
Ace - you can find OEM parts or repros over on the Ibanez Collectors World forum.
