I bought these to not only change the hardware colour from silver (nickel) to gold on my Midtown Custom, but to also get the 'tulip' shaped tuner keys.
The tuners were a direct replacement for the standard nickel rounded button Grovers, so no new screw holes required, very simple to fit. The tuners are of a very good quality, with no slipping or tuning issues are fitting.
Arrived in standard Gibson packaging, shipped quickly by Thomann, would recommend these for both a change in tuner button shape, or a direct swap if you are performing a gold hardware conversion on your Gibson Les Paul / Midtown or similar guitar with Grovers fitted as standard.
