I recently put new DR strings on my bass. For awhile I couldn't get any note to play clearly above the 12th fret; I was getting that flat metal scraping sound that doesn't play the note. So I figured I'd let them sit and try a little stretching. Eventually they started playing correctly up the neck but I've still been having trouble playing notes from the first through third frets. Most of them play but I can hear the scraping sound and it still appears as if the strings are tight up there and playing a note causes the string to scrape against a note a half step or even a step away and produce the clanging sound at least partially. Do I still need to try to stretch out in that area or is there anything else I can do to get clear notes to play? Thanks.
