Hello, I have a 1985 Fender Precision Lyte, with EMG PJ and BQC system. I bought the bass and did this upgrade after hearing thaddeus tribbett live with jill scott playing on the same setup. The bass sounds and feels amazing. lately I have noticed that the lowest E,F and F# sounds thin compared to the overall sound of the bass. when I go up from G on the E string, or on the other strings it sounds just amazing. I have tried DR sunbeams and Ernie Ball strings.. same problem. Any idea what could be the problem? Many Thanks!!
