The way I understand it the classic Fender 7.25" radius is suppose to be easier to play big chords on since it more closely follows the curvature of one's fingers. So I don't understand why I can play longer on my Martin Acoustics (with a 16" radius) before my hands start cramping than I can on my Tele with a USACG neck with a compound radius. I make a point to use less pressure and of course it's easier to fret the Telecaster anyway. Am I doing something wrong? Maybe I need a new neck with a flatter radius. ?
