Need help with neck issue..
I am having an issue with what i think is the truss rod. I have an epiphone tbird and my top (E) string has been going out of tune when i strike it. After further examination i noticed that the neck is curving down near the head. Im a newbie when it comes to truss adjustments, but i am also a working musician...so i have no cash to get this looked at. I am wondering if anyone has any words of advice or instruction on how to fix this problem. Fyi: i am downtuned to C, and am using 105 gauge strings. Thanks in advance for any help
