[Good tuners for G-400?? help please]

does yours have the grovers or the epi klussons?

 

it has the stock grovers on it.

is there a way to get grover locking tuners and replace the heads with keystone style ones instead of those odd oval ones?

By "slippy" i mean they don't stay in tune long, especially when its colder or its been in my case for more than a few minutes. It won't even stay in tune for long while i play.

[Good tuners for G-400?? help please]

I have an epi g-400 and the stock tuners are getting too slippy for me. I need to know the shaft/hole sizes of the guitar and what locking tuners people would reccommend/suggest? there are some nice Kluson ones i saw and the shaft size was 25/64". what does this mean? can it be converted into a "mm" size that can be related to the hole size of the guitar?

I would like some locking tuners that have keystone heads but i will compromise locking ones for some very nice normal ones. Suggestions please?? I need help from someone who knows what they're talking about.
