I recently changed the strings on my samick avion 3 and i can't seem to get the action and intonation where i want it. I adjusted my action so that my strings are closer to the fretboard, but now the twelfth fret on the low E string is buzzing horribly. All the other strings are fine and I already tried adjusting the intonation on the e string but it didn't do much. I don't understand why the one string is buzzing but the others are perfect, please help.
To clarify, i know how to adjust the action and intonation but my e string is buzzing so bad from frets 10 and up and adjusting them isn't working.
