At my school, we were all required to be proficient on both instruments, and in every genre. I believe one thing that hurt me in band auditions was my funk grooves. I've been shedding that quite a bit since I left school.
I see myself as a multi instrumentalist. I play whatever I get paid for (lately it's electric bass in this city). I have been able to separate techniques among the brass family, and had no trouble starting on upright, but when I got to electric bass, I was applying too much of my upright knowledge to electric. My teacher, Dennis Marks, told me to treat it like a different instrument. Ever since that, it's been easier to get across obstacles on the instrument. I haven't been playing my upright much in the last month or so, but I was putting equal amounts of time on both (well, all four instruments that I might let myself get hired on) in the shed. I try to practice similar stuff on each instrument, but I just don't think I will ever be able to slap/thump on the upright.
