Curious thing just happened to me... Playing a groove that has a double stop on the 7th fret, 1st and 4th string. I hit it, and I'm getting really bad fret buzz on the G-string. I try hitting both notes in sequence - no buzz. The only time I get buzz is when I press both strings down. I even tried the double-stop, got the buzz, and lifted my finger off the E-string, and the buzz stopped - put it back on, and it starts again. I even tried hitting just the D on the G-string with my finger in the quirky position it needs to be in to perform the double-stop, and no buzz. Anyone ever have this happen before? It's almost like putting pressure on the E-side of the 7th fret is causing the G-side of the 8th fret to rise. It happens on the 6th fret, too. It only happens when both notes are on the same fret, tho.
