How about Canon. Not only is it used as a musical term, but also as a religious one as well (as being inspired by God). Perhaps you might add something more if you want...like maybe some pun/play on words of the weapon, cannon. I dunno, otherwise next time you're at church or reading through the bible just pay attention to any phrases, themes, and words that pop up.

As for the cheap, but nice (and loud) acoustic, I very much recommend Seagull. My Dad has one and it's a great guitar! I believe GT's own Tonja has one as well if you wanna ask her about it. But yeah, Takamine's are pretty good too.
