I didn't know Martin's delving into archtops was a failure??? I have one and it is my favorite guitar. It has the most comfortable neck I have ever played, kind of like their "modified 'V'" neck on steroids. NOT real chunky, just comfy. The guitar has a 'domed' top with the solid spruce bent over curved braces. The back is a typical flat back in the 00 body size. I just love this guitar. It has an 'archtoppy' and 'flattoppy' hybred sound. I use it for playing blues, but also Beatles and some jazzy stuff I'm working on. Very versatile in my opinion. Here, enjoy some pics:
