Doublenecks have always to me embodied the concept of "rock star excess". Ever see an earnest singer songwriter play a doubleneck? Or any musician in any genre of music other than prog or hair metal?* Even the most understated, tastefuly finished doubleneck is still the equivalent of leather pants.
Not that I'd ever have the money or a reason to do so, but I think it would be fun to put together a 20 string doubleneck: 12 string guitar, 8 string bass. Y'know, just to turn the ridiculous excess up to 11. :headbang1:
Speaking of 'up to 11'..... I would consider it mandatory to play "Big Bottom" as soon as it was strung up. :icon_jokercolor:
