I wasnt planning on holding a note for 90 minutes or anything, but with a 'fretless' guitar the note that you finger connects with the fingerboard not the frets, obviously the best place to look for sustain is the fingerboard as this is the first point of contact, but I have this in hand at the moment and was looking for at the next point which would be the neck and rod...

basically I want to build a guitar with the best posible sustain, and I have heard the the truss rod can impede sustain and cause dead spots on the fingerboard, I dont want to put frets on this guitar so sustain is a must, as is no dead spots...

Hi there, I want to build a guitar without a truss rod to improve the sustain, how would I go about doing this, I currently have 3 laminates that will make up the neck; 2 rock maple with a center laminate of bubinga, could i simply epoxy a carbon fibre rod in place of the truss rod to increase the stiffness?
