I recently bought a Mustang short scale PJ bass and would like to put some flat wound strings on it. I wrote to Fender on their web site three times and got no answer. Has anyone put flat wounds on a new Mustang PJ and if so, what kind worked? Also, I asked Fender what kind of round wounds were on my bass when new. No answer on that one either. If I have to cut long scale strings to fit, how difficult is it? Any help would be appreciated. I wondered if Fender didn't answer because there are no strings that fit and they didn't know how to tell me.
