It hasn't shown in the MM guitar page for some time (2019ish?). My assumption is it was discontinued and the vault was left-over stock. Its a shame - always been on my list of guitars I'd like to acquire at some point. Always used of course, but still fun to look at the new ones and see new variations.
Well that's a shame. It's a great design, but unfortunately it looks like people don't agree. There's also just a TON of competition in the set neck HH guitar world I guess.
