Well you take the good with the bad on these demos for what their worth,.....I never put anything into a demo vs playing the unit myself and making a decision with my own two ears..if I like it I'll keep it for a while if not Bye Bye,...I will say the BK9 is intriguing and does have many kool attributes for the gigging player.
I would love to try one,...who knows it might be my next KB....
just sayin'
