I just bought a 1939 Martin tenor and the case is not the original. The overall "structural integrity" of the outside of the case is decent and the inside felt is ok too (not great, but ok), but, the sax is quite loose in there. It was packed super well when shipped, but now I would never transport it anywhere in this thing. I get nervous just hearing that "clunk" when I stand the case up. So I don't. I "could" shell out for a new Pro-Tech or something, but, I kind of like the look of this old case and I'm not real anxious to spend more money....so I'm wondering if there are any good tricks to making old cases work. I'm talking about filling the free areas with "stuff" of some sort to make the horn and neck not move, without being too much of a PITA every time I put it in there. Any ideas?
