I have a MIA Jazz Deluxe that looks and sounds great but has a problem with neck dive. I find myself constantly aware of the neck slipping while playing and it becomes a distraction during gigs. Several years ago during a gig and in an intense moment, I felt a sharp pain in my upper left arm......I'm right handed... and I couldn't hold my bass up for the next 6 months. I was playing this jazz. I don't know if the injury had a correlation with constantly holding the neck up but not being able to play scared me. Can anything be done to help with this problem?
