Hiya. Yesterday I finally bought an SB-1000 (paid 340/$, not bad I think). It's a bit beat up, but otherwise beautiful and I love the feel and sound. The action was really low, and while it was comfortable, my band detunes so I released the truss rod a bit. Today as I tried to release it a bit more it just came loose, like any screw. It didn't come out, but I had to tighten it again. Could it be it has a rod like the Rick 4001 (loosen, twist neck, tighten), is there something I'm ignorant about or is this beautiful thing just played to pieces (it's from 1980)? Thanks for any help.
