I've had a Vox Virage for over 6 years now, and while it is a favorite in my lap on the couch because of its awesome egonomics, I have never gigged with it because the tuners are a MAJOR weak link. I love the tuner knobs but would love to find a decent Gotoh, Schaller, etc. machine replacement that will easily retrofit. Optimal would be a fit without additional post hole reaming, same-fit mounting screw and a thread that accommodates the really nice S-shaped knobs. But either way, these tuners have to go. All experience and suggestions greatly appreciated.
