Hi - The guitar player in my band owns a '66 Precision bass - and it's got a problem. It has a very loud attack transient when playing the low E string. A distinctive static-like pop that comes through the cabinet on each note played on that string. It does not matter what setting the volume pot on the bass is set for, tone pot has no effect. Volume on amp has no effect - has to be pickup related. And ... ? What's going on here?
