Demon rattles whenever I manhandle him. I hope it's just a piece of wood from his busted screw hole [which I did not cause!] finally broke off. I should take off the back and check it out. But I don't want to. I don't want to have another broken instrument.
[In some slightly related news I took the rubber band that was keeping Igor's wonky strap lock quite, and that rattling I don't give a shit about when compared to his shivering truss rod cover.]
