Re: Rattling klusons!!!
Nope. The bad design is such that you can't tighten them. I still like Klusons, tho, mostly because they allow a neck to resonate far better than highmass tuners like Sperzels.
Before you go and make the mistake of fitting your guitar with another type of tuner, go shopping SPECIFICALLY for Kluson style Schaller tuners. They look and fit exactly like the stock ones, but their travel is nice and snug, and I think they have a better tuning ratio. I have those on my Goldtop, after encountering the same thing you're talking about. Problem solved, and there's no difference in the look of the guitar, and no devaluing holes or indentations left by using a modern style tuner.
