Back in the day it used to be Sperzel, but now I'm seeing a lot of boutique guitar brands using Gotoh, Hipshot, Schaller, Grover and Graph Tech Ratio. There are a few that have their own branded tuners as well (which are very likely made in the same factories that supply the aforementioned brands).
What's everyone's favorite?
