I've had teachers and mentors all throughout my saxophone life who have warned against the dreaded right forearm/thumb pain, but alas, it is upon me. I am trying to nurse this thing before it turns into a serious injury, but I find it worst after I play my Mark VI bari (main axe at present). My solution is to just place my thumb ON TOP of the plastic thumb hook rest, and that seems to work ok, but every time I forget and slip it under the hook, the pain comes back hours later... I wanted to ask if anyone else feels like the Mark VI bari hook is particularly low? Is there any aftermarket solutions anyone knows about?
