I'm thinking of buying an acoustic guitar somewhere in asia-particularly in Cebu- the guitar city of the Philippines. They make guitars out of unusual wood (bamboo, kamagong, jackfruit, ply wood etc.- if you guys know anything about the sonic characteristics of these woods, i'd be glad to hear anything from you) for very cheap price- and I'm very curious as to how it sounds. However, I heard that many of the unknown/ no name acoustic guitars/ home made acoustic guitars that they sell there have no truss rod. I guess it's ok if you're playing that guitar in that country because there's no winter- only sunny and rainy season, so i guess they don't have to adjust things all the time like we do. But my main worry is if that if i ever buy that guitar, would it ever survive Canadian weather? How do I go about fixing the neck anyways once it starts warping if there's no truss rod? Does anyone know how to set up a guitar and fix the neck of a guitar without a truss rod? thnx.
