The Peavey Micro Bass is perhaps deeper than a small suitcase but it's length and width are smaller. And it's light. I've taken it to parties and been able to comfortably play with 2 acoustic guitars and 3 - 4 hand drummers (bongos and stuff) with a Lakland fretless 5 string. No problem with the B string although it's not super sparkly (clear) and it doesn't like high output from active electronics but I just keep the master volume on the bass down if I'm using a lot of bass EQ boost.
It would be the amp that I would take if I was playing with acoustic guitars and I would have no need to complain about size or weight.
