No the thread isn't about butt floss lol. There is plenty of that stuff on the net as it is lol. My g string rattles like crazy on my bass and it kind of sounds like it's structure but it only happens on the g string. It makes its noise on open g and on a flat and thats it. I have checked cleats and seams and didn't see anything loose or coming up but could have missed it. I have also have heard that it could also be the nut is to low for the string. I will check this one out because it sounds most like my problem but like I said it has a structural sound rattle but I wouldn't know the sound of the nut being to low. If this is the case, fingers crossed that it is, what is a way to see with out buying a new nut for no reason? Also any other ideas? Thanks for your help people. Brian
