The thing that all of you are missing is that you are referencing acoustic guitars. Unless the poster started this topic in the wrong forum, then he was probably questioning about solidbody electrics. Using the acoustic examples is sort of weak, because as previously explained, the top is essentially the amplifer of an acoustic. Opposingly, i think wood will make a difference in solid bodies (but as previously stated) it will be very minute. Any way, please dont get mad at me, i think the way i wrote things may have came off cocky but it was really not meant to, in any way, offend anyone.
