I have buzz on my 3rd and 4th strings ONLY at the second fret. What do I do? Is it a do it yourself thing or do I have to go to a Luthier?
Might be a high fret.
Check by rocking the long side of a credit card on the fret. If it does rock, it'll probably be high.
If you're sure it's a bit high, a luthier should be able to fix it cheaply
