ataylor,
I agree, I think I'll go to an open gear tuner sometime on my 412. I haven't done much research yet but a little drilling wouldn't bother me. Hopefully there's enough room on the back of the headstock for Waverly's.
I haven't really looked into it cause it's a ways down the road for me.
Open gears do give a nice "vibe", one that I like anyway.
