I was going to get a set of the Gotoh Magnums for my Classic Vibe Strat but they're out where I looked. Then I came across the Grover 505 FV Roto-Grip series that fit the vintage Kluson style holes and mount screw pattern. Perfect fit. One of the stock screw holes was drilled off-center from the factory on the neck so I had to redrill just that one. They are nice and smooth. Don't look bad either.
I like the Gotoh Locking Vintage Oval Knob tuners too. Had them on another neck. Unlocking was done from the top but stringing up was pretty simple. Line the hole up, string through and then use a string winder and it'll lock as it turns. Took some getting used to.
I like the idea of drop-in replacements without having to enlarge holes and stuff.
