Depending on how much you dig the Bass Buddy, you could look into SWR's Amplite to use with it & your Bag End. That would be a sweet setup.
I split up my rig that was pre (PJBB) and power setup, but the amplite might not be bad. I love the PJBB, but was looking for something a little different tonally. It is crystal clear and clean. I'm hesitant to get rid of it, though, because I record with it, and I have had two different engineers at two different studios tell me that they CAN'T get any noise out of it, no matter how much they push the faders up.
