I have a Mastercraft Classic and have been having problems with the third string buzzing on the 1-3 frets. I've been periodically tightening the head and it seems good to me, but the bridge has taken on a bow kind of and the middle is sitting about 1-1.5 mm below the sides of it due to it kind of bowing at the bottom. This of course has lowered the action in the middle.
Is this normal bridge behavior? Do I need a compensated bridge or should I get a taller one? The rest of the strings play and sound great and it has a nice low action but I'm really put off by the buzz on G.
