My 7's been buzzing like crazy for several weeks now. Initially I thought it was the strings having that fresh-string sort of buzz, but it's only been getting worse. It's my Douglas Scope 727, it's buzzing like crazy, no matter what I adjust. I've spent a week trying out different truss rod tensions for the neck, and different actions (waiting until the next day to make any more changes, so as to allow the neck to relax a little bit). But nothing kills the buzz. It's either really bad buzz or really really bad buzz. It's on every single fret, regardless of how I press them. Notes still ring out, but it's audible in that it hurts my tones and kills the sustain. It's currently strung up with an Ernie Ball 8-string set, .13 - .74 in drop F. What sucks is that I can't take it to any techs, because none of them know how to work with anything lower than drop C, let alone a 7-string in an 8-string tuning.
