These tuner are perfect in everyway

I put these tuners on all my guitars that originally had Kluson deluxe style tuners. Make sure to purchase the seperate bigger size bushings if you are putting them on modern Gibson USA guitars. Finally a split tuner post got 3x3 guitars. The ratios gearing makes perfect sence once you get used to it. I would never go back. I used to use Sperzals in everything, but am starting to have a hard time getting them anymore, but I am super glad these are available vecause I like them better.
