Is it normal for SGs, or any guitar for that matter to not be 100 percent free of fret buzz? I've set up my neck the way I like it - Gibson specs for action at the 12th fret and 0.25mm relief at the 7th. It's not as noticeable when playing gently, but when digging in for those slightly hairy cleans it is, particularly on the g string. I've used a fret rocker to check for uneven frets - everything seems ok. And afaia the neck is not warped. Raising the action helps but by the time I'm buzz free the intonation gets thrown well off. Is that just the price I have to pay for the guitar to intonate properly? By the way the SG in question is the iommi USA special.
