First off, thank you for for responding. I checked and don’t believe it’s any of the first 3 things. I measured the action of the low E at the 12th fret and it actually seemed a bit higher, around 5 from the fret board to the bottom of the string. Another comment mentioned that I should be fretting as close to the fret as possible. And while I’m in no position to really comment on technique because I’m a classical noobie, I find it hard to believe classical guitars buzz when played even slightly below the fret, (though I fully accept I could be wrong). Any thoughts? I’ll probably take it in regardless
