I was playing a fundraiser for my buddy's middle school that he teaches at and brought out one of my MIM jazz basses that I hadn't gigged with yet. I'm not much of a knob turner so everything on the bass is always full on. I realized that it sounded pretty different from what I thought I remembered and thought I forgot to bring in the back pickup. For some reason when I soloed the back pickup it sounded incredibly thin, almost like the strat's out of phase sounds. Has anyone had this problem or does anyone have any ideas as to what it could be?
