Hans,
The most recent reference is a 1995 X-170 currently listed on e-bay with a starting price of about $1350 (no bids yet). I have sent the seller an email requesting a confirmation that his guitar is indeed fully hollow. Regarding the other I recently saw, I can't recall if it was on craigslist or ebay, or if I came across it while searching the net. It is entirely possible that it was/is the same guitar, but I do clearly remember seeing another mention of a fully hollow X-170 over the last month. I will let you know about this guitar currently on e-bay once I hear back from the seller. I would love to have a fully hollow Guild, more specifically an X-500, but I shouldn't be spending what they cost, so I thought a hollow X-170 might be a decent alternative for now. Based on your reply it sounds like that is not the case. Thanks for the reply,
Dave
