Just won an auction on a '72 Guild F212. This is the mahogany back and sides F-40 shaped small jumbo 12-string.
When I get it, it is going to have an overhaul like you wouldn't believe. Tusq nut (a 12-string at that), Tusq bridge saddle and pins, JLD Bridge Doctor, and maybe all new open-geared Waverly tuners!
And of course, new Cleartone strings.
Does it really need all that stuff? Probably not, but I believe in after market mods, and these are simple, inexpensive improvements that surely enhance the already beautiful sound of a great guitar. I also believe in using every tool and gadget available in the purpose of getting every bit of sound out of an instrument, and these mods will do that.
Can't wait.
Yes, Tusq is the way to go. They make all sizes for all acoustic guitars.
