Ditto, that: OM2HG custom it said on the label, for the deep body. It was my first Collings and it was wonderful. I have a friend who got the same thing a couple years ago and it was an extraordinary guitar, too.
That said, I have gravitated to non-deep bodied Collings and like them more, I guess. I would like to play that OM2HG custom again to see how it sounds and feel to me now. I am pretty sure I would want to buy it back...
