Re: Old tuners on a strip-72 F112-are mini tuners better?
I have a '68 F112 with original open-back tuners. I like it a a lot and play it frequently. The tuners are in good (but not great) shape.
Last year, I had a '70's G312. It sounded very good but it had mini-schallers (or grovers) on it. It was very neck-heavy and the neck dive was not fun to deal with. So, I sold it. I'm glad I did, because I play the F112 a lot more........
My point is, get some good tuners, but get the lightest tuners you can to replace the originals. That probably means open back tuners, or certainly 'on-a-plate' tuners. Does any body make an open-back 12 set these days? I dunno. I just did a google search and couldn't find any. Maybe check with WD Parts and see if they have some. I think WD owns Kluson, but I'm not sure.
I think there are some threads here about fixing up (tightening up?) the original japanese-made tuners, too.
Good luck.
