Anyone played one yet? No, you say? I thought not, but let's just write them off based on the pictures, eh?
I used to own a fretless Marathon 6, and I liked it well enough, but I always wished the body design was more elegant, and comfortable, and find the distinctive headstock just clunky. I really wanted to love them more, but imo they never came up with a great looking design.
The double necks did look impressive though. I roadied for a friend's band (called Media) that had 2 6/4 double necks, back in the 70s (and bass pedals too!) Eye-catching, but a bit out of step with the zeitgeist of 1977...
