I think my 2001 MIA P-Bass's E-string sounds dead on any notes lower than A on the 5th fret. I just changed from Fat-Beams to D'addario Chromes flat-wounds and it didn't help. Although I'm diggin' the flats. The A string seems to have much more punch/thump. My pickup is level and my strings are at an even height. Is this just a trick of the sound? I wonder if it's just because I'm standing within 6-8 feet from the amp. Anyone else have this problem?
