I picked up a Harmony Sovereign for cheap and was thinking about changing the tuners out. It still has the original open back tuners on it, but both the D and G tuners are bent. I was thinking about going to Grovers, but the shaft seams like it is too long and would stick out way above the head stock face and there wouldn't be much of a string break over the nut. If you've done a tuner swap on a Harmony, what did you change to and how do you like the guitar now? I also looked at using a set of three on a plate re-issue Klusons, since that would keep the original look, white plastic oval buttons and the shaft is just a bit shorter than on the Grovers. Thanks in advance.
