i bougt an exr170 2 days ago,i'll use it as a backup guitar...There was 2 problems while setting it up..
1-)The low E and maybe A strings are buzzing if i pick a little hard,i checked the action and it's normal as the manual says.I don't know why it is buzzing,i thought the new strings can buzz a little but i'm not sure about this

..
2-)The single pickup is high for me,i tried to lover it but it lowers with an angle,when i lower it,the bridge side of the pickup lowers very much and the neck side lowers less than the other side(hovever it's a single pickup).How can i lower the pickup and make it paralell to the body?
