Slowly losing my cool with this one... I bought brand new Schecter Banshee Elite 8. Great guitar feels great etc BUT I cant get rid of fret buzz on the low B (7th) string. (and a little on low F#(8th)) The buzz is mostly between the 7th and 10th frets. I brought it to a shop and he said the neck got a too big bow so I got it set up. Now I get it back and its still there. ALSO no matter what I do I cant bring the low B into tuning. I tune to E A E A D G B E but now matter how I accurately I tune the low A, power chords always sound off. Wasnt like this before the set up. Even tuning it lower a few cents doesnt help. Action on the low B is like 1,8mm Low F# string action is 2ish mm I use a .60 for the low B tuned to A .80 for the low F# tuned to E I really dont want return this thing because it literally has everything I need but these issues slowly make me rage.. Help?
