I’ve a tear in my rotator cuff muscle in my right shoulder that over the years has affected my whole back with regards to posture amongst other stuff. This year I’ve also put my lower back out a few times including a bad one around Feb where I was in constant pain and had (and still have) restricted mobility, though fortunately not too bad. As such I’m now at the point where the weight of a bass is a very important factor, for this reason have gone short scale.
