I play with the pot rested between my legs and recently on normal scale banjos my shoulder gives me major fits. It started after long playing sessions but now happens within minutes. i have tried the pot on the right lap method and in helps to bring the shoulder down and closer to the body. This is just not comfortable. My 23 inch banjos seem to be the limit of painless play.
Apart from playing A-scales forever what have others done to help. Am I alone in this or are there others?
