The earlier announcements of the Archon 2 and the HX/DA-minus-Duane models pretty much stole any thunder they had for Exp-21. Slow times when paint is the news.
Experience as a program to watch was good, though. They gave a lot of well-deserved spotlight to the craftsmen that make the guitars and amps, and to the musicians who use them. It was entertaining to watch, even though there was little “news” to share.
