I having trouble finding material on my issue: This is a new guitar, it played fine. I did take it out of town with me but I never left it in a car.
The string gauge is .11's
Here are my problems:
INSANE fret buzz on the low E. I did not notice it until I tuned a 1/2 step down.
When I returned to standard tuning, the fret buzz was worse and now the intonation is severely off. On the 12th fret "E", the fretting note is registering F and the harmonic is registering E
No problem with the rest of the guitar. I don't know where to adjust or how to go about it.
Edit: Here are close pictures. It' does look like I am able to adjust the string height. I just don't want to play with it until I get good advice and see a video on it.
