You could also ask why electric basses are so cheap. $35k isn't even entry level for a concert quality violin.I'm with you. I can't see or hear the appeal. But then again the video posted in this thread is also baffling to me. So I'm definitely not the audience for either the music or the bass.
I still don't understand what can possibly justify the $35,000...sorry, $35,200 price, lol. What's the 200 hundred bucks for?!
It could be a fair price for a bass with a similar level of fit and finish while allowing the luthier to make a living wage. Most custom guitar and bass builders are barely profitable at best.
