hi, all, im still a somewhat beginner playerc with upright, on a 70+year old kay bass. last year the neck came unglued whuch i was able to repair. but since the action and srt up is still really bad, with really high string heights especially past the first octave(making thumb position alnost impossible.) im trying to get to a Luthier, but mostly right now im just really curious if it's still beneficial to practice if im hurting my body every time I do it?
