So I've set up my guitars for quite a long time, but I wanted some outside input to maybe get a fresh perspective. On my RGA8 I've been using the following string gauges from high to low: 9-12-15-22-30-40-54-72, which tension wise is great and feels very even across the board. All this time I've had this ANNOYING ass buzz on the 6th fret on the 3rd string, and I can't seem to get rid of it no matter what I do. I can set intonation, that's a very easy thing to do. However, I need some outside opinions on the rest of a setup: trussrod setup (how to measure/know when it's setup properly, etc), string action (high e height, measured from 24th or 12th fret, on the 8-string should i measure the low side action on the f# string or the low b/low e, etc.), pickup height, etc. I know a lot of this is up to taste, but I wanted to get an idea from those experienced with this type of thing because this one fret is getting VERY annoying, I've tried hammering down the fret in front of it, having the fret filed, all kinds of stuff and this is driving me insane! And I don't really want to bump up to a higher string gauge as I like the tension of the strings as they are right now.
