I use sitka for back braces on my dreads and thinking about using same for my OM. So far I have used lattice bracing style, but was thinking of using X-bracing on back. Is their an advantage to spruce VS mahogany? How much of a difference has anyone found in lattice compared to X-bracing in the back?? Sound or even structural wise? What material are people out there using for side reinforcement? I use mahogany. And finally what are the arguments of Dovetail neck joints compared to bolt-on? I am trying to think out the next two guitars and plan things so I can be ready. So I thought I would throw a question or two, so I would get some input.
