I have a wonderful Martin 000C-16RGTE that I got from a fellow TGPer and am wondering the best course of action for lowering the action? It sounds magnificent, but for being an almost $2000 guitar, the action isn't where it should be. A buddy of mine who has attended a luthier school in California and built his own very nice acoustic told me to shave the already tall stock bridge. Is this where I should start? How much is an acceptable start? 1/16th? What is the best way to shave it? Sander? Help me out here please!
