Re: Gibson vs Grover tuners
I upgraded to the Gotoh locking keystone tuners on my LP Standard, and I really like them. I agree that unless you have a broken tuner or other major issue, there is no need to change tuners if you aren't going to upgrade to locking tuners. The locking versions make string changes a breeze, that's the main reason I like them.
If I didn't care about keeping my guitar "vintage" looking, I'd upgrade to locking Grover tuners...these are the best tuners I have ever used.
