Hey pasta,
Nicely done ...beautiful guitar! This is an 05 I take it? So that's ES1 with AA batts if I read you right. The balanced output doesn't affect tone whatsoever, just so you know. It's useful if you can't get enough gain to the board (you get a 6db increase with the balanced out), of if you simply want to plug into a console or DAW interface directly without a DI box. But as for tone, the balanced out changes nothing beyond a hotter output, just so you're not expecting something that isn't there.

Best to you on this guit! I never planned on getting a maple acoustic, and somehow ended up with three. No kidding, not on purpose, just happened to run into these guitars at
different times, over years, and each one bowled me over enough to bring it home. First a 12er, then a dred, then a GC body. Weird, I know! And that was well over a decade ago, and
still these guitars give up nothing to today's offerings, Taylor or other marques! That's my story and I'm a stickin to it. Enjoy in great health and many smiles!
