I have a Musicman Stingray 5. All the other strings sound awesome, but the B-string really sucks. I've put new strings on and changed the battery and had the bass professionally tweaked, but for some reason it just sounds dull like there's a blanket over it and it doesn't ring as clear as the other four strings. All I really want is for the B-string to match the rest of the strings in tone. Does anyone have any insight as to what can be done or something that may have been overlooked?
