Also maybe check out ergothérapie, they are awesome with this type of thing.the initial setup tuned to E is higher than normal tension. i did drop that down a bit by tuning to C.
i see where you are heading with the tension idea, and agree it could be contributing. the bulk of the issue comes from the left hip and low back area. there's something about the seated posture holding a bass that aggravates my muscles. part of the issue is weakness in my left shoulder and arm, making it hard to get into a good playing position. i twist my torso and over compensate with my abdominal muscles, which is another problem.
i think the real answer is - i need some PT, including some gym time and massage work.
i appreciate the support and encouragement from the crew here![]()
They'll evaluate your position, posture, suggest alternative work positions etc.
