geronimotwo, both of the tuners I was using clearly show sharp and flat. The two tuners are very close in their readings, so I guess I trust them.
Fitz, I'm in the very northern part of Alabama, in Decatur, just west of Huntsville. I'm checking the tuning now after each hour or two of playing, and it's not off, or off by just a teeny bit.
I took one of the small velcro straps for the amp to guitar cable and hung it on the high E chord. No more problems with hitting that string when I'm trying to strum hard across the strings. I can mute the A chord with my index (basse) finger, but I can't bend the finger properly to mute the high E string while still holding down the other three.
