You'll probably want to choose an amp that's designed for upright bass instead.
Many BG amps are voiced for that instrument.
DB amps are usually flatter, have a more linear response.
But some amps are good doublers, they give good results with both kind of instruments.
Your profile doesn't say anything about your gear!
