+1 to that.
The output from the Baby Bass is not particularly powerful, but run it through any preamp pedal (I've used Sansamp BDDI, Hartke VXL, MXR M81) or active DI box (I've used Fishman Platinum Pro, Radial Stage Bug) and you'll be fine.
Just because it looks like an EUB doesn't mean you can't use normal electric bass pedals with it.
ps: I've just noticed that, in the photo of me playing with KK at Proud Camden (above), I'm running through the Sansamp, and that's going straight to FOH with no backline at all.
Unexpected extra bonus was that the band following us were a touring outfit of Australians travelling light - their bass player (Fender Jazz) was expecting to borrow someone else's backline and was a bit put out to find none there. So he borrowed my Sansamp and went through that instead. Happy as Larry, he was.
