Hi All. I have recently retrieved my short scale Samick bass from a long stint in the shed, shouted it its first ever set of new strings - Thomastik JF324 Flatwound Jazz Strings. I am thrilled by the tone of these new strings but I am having a problem with the low E string - The sound from this string is very muffled/muted/dull compared to the other three strings. Can anyone help me diagnose this problem? Could it be a problem with the pickups? With the set-up/ action of the strings?
