Thanks for all the advice!!
Guild has been nice enough to ask around their service dept to see what they think. Will report back.
Alas, for the fourth day I have tried many options again to no avail.
Yes, that barn door looks like its only purpose would be to put the harness in. You are probably right.
But I think Korea would have rather cut a bigger hole through which to pass their completed harness, because this one cannot come out thru there.
Every configuration and positioning of both pots, even with wiring moved so as to not inhibit egress failed.
I am convinced they either put bald pots in thru the barn door and wired up the harness thru the f-hole (yeah, right) or they assembled the harness and connected it to the face before closing the body.
Is it possible they finished the individual pieces of the wood body first, then glued them together, then put on the binding, but then they would have made an unfixable instrument. Weird.
May be time for the Dremel to carefully widen the barn door in the pup cavity. But I will hold off on that until I hear conclusively from Guild.
