Hello! New to the forum! Recently acquired a late 70’s Bluesbird 77 to be exact. The Neck binding has split and the price reflected the issue. Everything else on the guitar looks and sounds great. I have a skilled guitar builder friend in Seattle who will repair the guitar and get her back to the glory days. I’ll share the journey here if anyone is interested. In the meantime, I couldn’t find much chatter about the late 70’s M-75 guitars.. wondering what your thoughts were! Thanks Kellin.
