My only bass is a 50s Kay that I think sounds pretty good for orchestral music even with Spirocores on it. I mainly play jazz, but I recently got asked to do a serious orchestral gig that is too good for me to turn down, so I am practicing my ass off. My question is...are there any serious orchestral players that have ever showed up to a gig with a Kay plywood bass? It also is blond, so I am a little worried that I will look out of place. Should I be concerned about this? Will the sound and look of the instrument not work well in a serious orchestral situation? I really don't want to borrow another bass for this gig because I am already comfortable with this one.
