That's different and truly unique. Would be a B#@ch to play sitting down unless that is a Steinberger type fold out bit I can see hanging off the bottom edge?
Had a Flying V for a very short while some 30 odd years ago and was it a PIA to play sitting down. The only way to do it was to wedge the V across your right thigh thus pushing the neck plenty to the left. Standing up playing it was only marginally better as it was hard to find the right balance with rear strap button placement. Great look, average sound that was a bit too shrill when compared to a LP, and moved it on after about 6 months of ownership. Would only buy another one as decoration.
