My B,G,A and E strings buzz open and in everyfret, what kind of setup should I do?
Raise the saddles a bit. If that doesn't help, check your nut. Maybe the grooves are cut too deep, as it's worn with time. You can get a new nut made at a guitar shop for about 50 bucks.
raise action a bit?
I don't think it's the nut because the guitar is 2 months old, I'll try to raise the saddles, and thank you guys.
