I also just this second finished installing the 6 in a line mini locking tuners. Went on no problem (accidentally drilled right through the headstock for one retaining screw. woops). after some cursing on how to work the buggers they are in and solid. Pretty impressive for something so cheap, though they don't cover up the two pins the old tuners needed on the back on the MIM headstock. Oh well, this is my RAWK telecaster anyway.
Also upped to using a wound third string. Welcome to Man Land, population, me.
