I've had a 5-string MTD Heir for a couple months now & have developed some tendonitis playing it. What I've found it that it's substantially neck-heavy & really wants to dive on me, and the weight also tends to dig into my left shoulder. Now, in every aspect this is easily the best bass I've ever played, but it's tough to play well when you're supporting the neck with your fretting arm... have any of you had this problem too? What have you done to counteract this? Thanks for any & all assistance!
