Kluson Revolution Diecast Locking Tuners, 3+3

Uses a modern 25/64 inch (9.92mm) peghole despite the vintage-look housing. One owner measured the tuner holes at about 8.3 to 8.4mm on a 2021 Casino Coupe, which would need reaming. No hole size has been confirmed for the 2023 and later Casino, so whether reaming is needed is unknown.

Kluson's Revolution uses a screw-in hex bushing built for a 10mm peghole (25/64 inch). Epiphone list the standard ES-335 with Epiphone Deluxe tuners and don't publish the hole size, so it isn't known whether the holes are the modern 10mm or a smaller vintage size. Take one tuner off and measure: 10mm means it threads straight in, anything smaller means the holes need reaming.

Epiphone don't publish the tuner hole size or mounting for this guitar. Kluson give this set a 25/64 inch (10mm) peg hole with screw-in bushings and their own two-screw mounting, and don't list which guitars it matches. Take one tuner off, measure the hole and check where the screw or pins sit before ordering.

Fits a 10mm tuner hole with a screw-in hex bushing. Epiphone list this model with Epiphone Vintage Deluxe tuners and don't publish the hole size. Some owners report 10mm holes, but vintage-style tuners can sit in smaller holes. Take one tuner off and measure: 10mm means it drops in, anything smaller means the holes need reaming.

Some units of this model have shipped with Wilkinson tuners rather than the Grover Rotomatics Epiphone list in the spec. Both sit in a 10mm hole, which is what Kluson's Revolution screw-in bushing is built for, so the headstock does not need reaming either way. What varies is the bushing being removed, which affects how cleanly the replacement threads in.

Hipshot's own published fitment guidance for the ESP LTD Eclipse states its tuner mounting screw holes are angled 45 degrees from the tuner body, a nonstandard pattern that aftermarket kits typically only work around by using a mounting plate rather than matching screw holes directly. The Kluson Revolution G-mount uses the traditional two-screw Gibson pattern, which may not line up even though the peghole diameter matches.

Shares the same Eclipse-body headstock as the standard E-II Eclipse, where Hipshot's own fitment guidance confirms a nonstandard 45-degree angled screw mount. That mounting risk applies here too, independent of this guitar's different bridge system.

Listings reproducing ESP's spec for the LTD Viper-400 give the tuners only as Grover, with no model named, and ESP don't publish the tuner hole size.

Kluson's Revolution uses a screw-in hex bushing built for a 10mm peghole (25/64 inch). Gibson list this guitar with Vintage Deluxe tuners with keystone buttons and don't publish the hole size. Gibson's Deluxe-style tuners come in push-in bushing versions, which sit in smaller vintage holes, and screw-in bushing versions, which need larger holes, so the hole size on this guitar isn't known. Take one tuner off and measure: 10mm means a straight swap, anything smaller means reaming.

Gretsch tuner mounting conventions vary meaningfully by model, some accept a standard Gibson-style two-screw Kluson mount cleanly, others use a different screw spacing that does not line up without a mounting plate or new holes. This has not been confirmed for the G6120T specifically, and forum reports are mixed across the Gretsch range.

This guitar ships with Schecter-branded locking tuners in 10mm holes on a 3+3 headstock, per Schecter's own spec. The Kluson Revolution matches the layout and hole size but uses a traditional two-screw mount (top and bottom of each tuner), and the screw pattern of Schecter's stock tuners isn't published, so the existing screw holes may not line up.

Kluson's Revolution threads into a 10mm peghole. Yamaha list die-cast tuners on the RSS20 but not the model, hole size or screw position, so the fit is unconfirmed.
