Also, wanted to say JAB that you only use the screw when you go above the C or G tuning on the third fret. Now what compounds the problem is that there are so manyn different banjo tunings available. Most of the traditional folk banjo players use the raised second string and there are variations on that. Check Doc Boggs, Clarence Ashley, Some Uncle Dave (uses a C tuning in a chord) and Buell Kazee. Lunsford and Derroll rarely used any variation from G or C tuning but Jarell and Bob Carlin, Mike Seeger and trad players all do.
