Very nice looking guitar. I'm thinking about it.......hmmmn.
There is a side of the fingerboard/soundhole crack showing in one picture.
Interestingly, there is some finish separation/shrinkage on the forward edge of the pickguard and the bass-side fingerboard edge, over the top.
Normally, I would say that the finish shrinkage is just that, shrinkage, but the crack makes me wonder if there is anything else loose on the inside, like the 'neck-block underside-of-the-top glue-join. I've seen that happen with Guilds (12 stringers) before, where the forward soundhole crack was the only visible sign of other issues.
It's not that it's not repairable, but if you buy the guitar close to full value, you may want to factor the the cost of repair, as well as a small drop in value into your final offer.
Why doesn't somebody email the seller about the crack and see if he had it checked out and knows 'one way or the other' if anything else is loose?
