Just got my X20, love it, but after a few hours of playing, i'm not sure if something's come loose or what, but whenever I play a D or a B, Drop D, or D or B string, or second fret on A, i hear a buzzing from inside. I've tried to isolate it and I just can't seem to! Anyone else run into anything like this, Sean, anything from Emerald? Thanks, Andy
