Although something is really really annoying me about it, and it's not the guitar's fault. I'm experiencing rattling from the body, not fret buzz, when I fingerpick the strings (I play bare-tipped so I hit the strings quite hard, not like a player with nails) and especially when I play open harmonics. Maybe if Jim sees this he could give some advice? It's so hard to tell where the rattle is coming from...I think it's coming from the bridge or inside the guitar. It's not just one string either, it can come from most of them and it's ruining the sound of the guitar because it leaves a buzzing undertone any help would be great.
Anyone any ideas? There's more info on the other thread. It's not half as bad on the Avalon as it is on the Maton, but it's happening nevertheless, especially with open harmonics (G and B strings on the Avalon, all over on the Maton).
EDIT: If it helps, when I capo the first fret on both guitars, the rattle disappears completely - possibly a problem with the nut?
