my bass is a short scale so how do I tell the difference. I thought my first bass was a short scale and when its next to my precision its about 2 inches shorter. What do I measure to find if its a normal scale or short scale? Would the serial number of my fender help? I checked it out on google and couldn't find anything on short scale fender bass serial numbers. Please help me. From headstock to butt it is 46 inches?
