To adjust your banjo head, remove the resonator, take your lug
wrench, if you have one to fit, start at the neck heel and turn your tee
wrench about 1/8 turn all way around. If you feel that it is still a bit
loose, go around again until the head feels tight. If you have the banjo
tuned to pitch, make an A note and kill the strings with the left hand
and lightly thump the head in several places and try to determine if the
tone of the head is close in pitch to the "A" note. If it is fairly
close in pitch, you have it in the ball park.
Give it a try.

like power and drive, while others prefer a more mellow sound. There are
many ways to set up a banjo and no single method that works for
