Adjust Banjo Truss Rod (Except Banjolele)
If you've never done this, we suggest you have a competent luthier perform the
adjustment. (Ask if you can watch... you could then consider doing it yourself next
time.) The truss rod in the neck of a banjo controls the "relief" or subtle curvature of
a banjo neck and helps counteract the pressure of the strings to help prevent
warping and twisting. An adjustable truss rod can be used to change the "playabili-
ty" of a neck by allowing the neck to curve a little more or by flattening the neck out
a bit more. Players with a hard attack generally need a little more "relief" in the neck
and players with a lighter touch generally like a slightly flatter neck.
1. Remove the truss rod cap with Phillips head screwdriver
2. If you have a capo, attach a capo across the fret before you adjust it.
3. Hold your finger down at 22nd fret.
4. Slip a credit card between the fret and the string at the 7th fret to check the
clearance. It should slip through easily without too much clearance or any rubbing.
5. If you have too much clearance, you may need to tighten the truss rod nut.
(Clawhammer players may want a little extra clearance to make it easier for the
right hand.) If you don't have enough clearance, you need to loosen the nut.
Too much relief makes the strings further away from the neck in the middle portion
of your fingerboard, you'll notice, as time goes on, it may be harder to chord beyond
the 3rd,4th fret all the way up to about the 10th, 11th fret. This can be adjusted by
flattening out the fingerboard with a little adjustment on the truss rod. You can adjust
it using the Allen wrench provided.
