Wow! As my mother-in-law would say: that's different! I'm not really a fan of how it looks, but I checked out some of the YouTube clips, and it definitely sounds like a bass! I don't know how I would fare with that skinny rounded neck, but the guy in the video seemed to find his way around okay!
I'll be interested to see what others have to say about it. I can think of many other instruments I could buy for 3K. I have to give the makers credit for trying something that I've never seen before!
