Someone on AGF has a Martin custom 000-18 for sale. Looking at the specs, the only difference is 24.9" scale vs. 24.75", abalone inlays vs. MOP. Not sure if the Martin uses hide glue or not. Of course it has Martin stamped on a back brace and not Guild. I wonder if it is just the Martin name/mystique that justifies the $1000 higher MSRP or is it something else. I know we tend to think highly of our Guilds, but even though I've owned a couple of Martins, they never impressed me the way they seem to some people, and I've played (although not often) pre-war and '40s Martins.
