Truthfully, I'm a fan of Grovers. All those iconic 'bursts back in the day were refitted with Grovers (mostly because the original Klusons were unstable and prone to breaking). The Kluson-style tuners Gibson is using today are fantastic. I don't have any tuning issues at all. My Les Paul stays in tune for weeks as long as the strings are installed correctly. I've really thought about putting Grovers on it for no other reason than that I think they look cool. Unfortunately, Grovers require a bit of reaming out the wood from the tuner holes in the back of the headstock so it's something of a permanent "fix" for a non-existent problem. And it would devalue the guitar a bit should I ever want to sell it (though I have no plans of ever parting with my R8. It will be my son's one day).
Thank you. I'd forgotten that Grover made Kluson-style tuners. The tulips not only look good on Gibson electrics, but they look good on the few acoustic on which Gibson puts them. It's a shame that so many Custom Shop Les Pauls don't have tulip Klusons (and that the trapezoidal fretboard inlays are replaced with rectangles).
I've toyed with the idea of replacing tuners on a couple of early to mid-1980s Martins with Waverly tuners (Waverys are my favorite tuners on acoustics, if you want the vintage look), but that would require reaming - so I've always avoided the temptation.
