Saw one of my favorite bassists play this past weekend and noticed that he frequently would play in the 12th position instead of in the first position. He got a great thick sound that I have been unable to approximate at home. I know I've got some minor intonation issues, but especially on the E string, some of the notes (especially the F on the 13 fret) have a really unpleasant honky tone. I also get a lot of fret noise (clank) on the E string. How much of this can I address via setup? Tips? Thanks in advance.
