I have had a SX Short Scale Jazz Bass for a couple months. I LOVE IT. I would prefer to have a Full size P Bass Body. Since the Short Scale Jass Bass neck is 2 1/2 at the end or fret board it will fit on the Full Scale P Bass body. The distance from the end of Fretboard to the bridge Saddles on the Short Scale is 10 1/8 the same as it was on my USA P bass. SOOOOO-if I just bolt on the ShortScale neck to the Full Scale body what sorts of problems might I have? Please tell me none !
