Hey Harry,
Welcome to LTG and congrats on the Guild.
I have played a couple GAD 12 strings and I echo what capnjuan says about Guild making the best 12 strings, even GADs Grot. :shock:
If it sounds and plays well to you, that's the most important step in become a guitar that will be played.
There are several 212 owners here and I hope they will welcome you and chime in on their experience, but one thing we do need is photos, otherwise this thread doesn't exist, and if you can do it, sound clips are always appreciated!! :mrgreen:
Again, welcome and jump in, the waters fine, though the gene pool is shallow at times. :shock:
