I feel like there were a bunch of problems with it when I got it. I know it's used, but it seems like some of it had to do with the initial setup from Gibson. The model, for reference's sake, is a 2005 Gibson Les Paul Standard Limited Edition. I was wondering if any of you had any experience with these: 1) When I got it, there was some awful fret buzz. I took it in to a shop, and he said that the nut wasn't carved very well and that there was very little place for the strings to sit. 2) It seems to go out of tune pretty easily. I don't know if the strings that the guy who shipped them with were new, but still, I've had it for a month or so now and I still find myself needing to retune pretty frequently because the G or B strings drop 1/8 step (other strings detune as well, just not as dramatically) I believe that some of the other stuff has to deal with the tubes in my amp possibly going microphonic, so I guess I'll just have to do the pencil eraser test and find out. However, in practice I noticed something interesting. If I didn't have my hand muting the strings, there was a really weird sound coming from my amp, but when I muted the strings, it went away for the most part. There was still more buzz than there used to be, though, hence me thinking it might be microphonic. Does anyone have any knowledge of this kinda stuff?
