Hi guys, Really hoping someone can help me diagnose the problem. I just put on new D'addario flatwounds on my Fender Mustang bass. Installation was fine, the D, A, and E strings sound great. However, my G string sounds terrible. It almost sounds like two strings are being played at once when I strum it. It doesn't sound in tune even though my tuner says it is. I can also wiggle the bridge saddle left to right, which I never noticed. It looks fine at the nut. I've tried raising the action. What say you?
