Hey Cory,
Zero concerns whatsoever about Taylor's 12 strings exhibiting problems tuned to standard. Not only have I had my '08 tuned to standard since then, I have not once, ever, heard or read any maladies reported on any Taylor 12er. Anecdotal, to be sure, but contrast this with the numerous issues reported with other 12ers I (and doubtless others) have heard/experienced over the decades.
Moreover, I love 12s, but never owned one until this Taylor because every 12er I had my hands on back in the day never played half as well as a Taylor, and always seemed to exhibit this or that problem, and this even when tuned down a half. This has been my personal experience, so take it fwiw. But it was this continual "let down" with 12s that prevented me from ever owning one, despite how good many sounded. So when I got my hands on this one Taylor back then, whooaaa ...it was an eye opener and a game changer. Fast forward to now, and that guitar not only plays just as well as back then, but just as well as today's Taylor 12s, which is to say better than
every other 12er I've personally had hands on. All imo and meager experience, mind you, but you did ask
Enjoy that 12 with abandon ...and post pics, will ya?!!
