Help: Fret buzz after tuning down
I have a EBMM Majesty, it has standard string gauge (10 mm high E) and I have tuned it down to C standard. The tension of the strings has decreased (of course) and I seem to get fret buzz, specially with “air” notes (no pressing on the frets) and the first frets of the fingerboard, maybe between 1-3.
I have read that I could solve the problem by changing the gauge of the strings or adjusting the truss rod. I just want to learn and play this one song in C standard and it costs 100€ to do a set up in my city. What can I do?
