I am doing research on acoustic guitar string tension. I understand that for a classical guitar the tension is about 120 pounds pressure on the neck with all six strings which is about 20lbs per string. In terms of acoustic guitar design where and how can the string tension be decreased with out sacrificing tone, volume and performance. I know many guitar builders have made improvements but where did they apply the improvement on the guitar? I would also appreciate if someone could direct me where to look for more information.
