Sometimes I’ll cruise ebay’s musical instrument pages (especially guitar pages) for a couple of hours looking for unusual instruments. Here’s one I came across today (the ebay # is 300129044775):
Here’s the main problem with this insturment. The fact that the “body” rests so high up the fingerboard. To play below the fingerboard/bpdy you’d have to slip your hand underneath where the body touches the neck and then up again on the fingerboard. Or you could play the bottom part of the fingerboard with your hand sort of parallel (flat) like a violin or cello.
