As said, a bass will sound different 'in concert' than it will at home/solo. At home, you tend to EQ out string noise, fret noise and 'clank'. In concert you need all this stuff to be heard. But you won't hear the string noise, fret noise, etc.
In short, when playing in a band at a gig: Mids, mids, mids. Low and/or high, but mids, and plenty of them. Don't have a load of extreme bottom end sloshing around either, it sucks up bandwidth and makes the whole band sound like turds. Turds!!
