I have recieved back my first mandolin ever with a popped brace (X) and the owner has left it strung up under tension causing the top to get quite a wow/bend in it. They left it strung up for several months. I recieved the mandolin back and had to bag it in a sealed bag because the mildew smell stunk up my whole shop to the point I couldn't stand it.
OK, we are talking warrenty here, first ever for this which I use hide glue....looks like it got very hot and very humid. I'm very upset about this and feel my fix would be just building a whole mandolin but who would let their instrument be in an enviroment that had so much heat and humidity? I'm of a mind to tell them my mind but they could say just about anything and make me look bad.
Fix it and eat the major labor? Confront them? Ignore it and send it back?
