Looks like a beautiful bass. 
 
On the price thing, the price is driven by what somebody will pay for a good or service and can be relatively unrelated to the cost of producing the good or service.  So if a $10,000 swing ticket still results in sales then that is probably the market rate for that thing with that brand. 
 
So very subjective, not sure I'd part with $10k for a bass personally  .
