I recently acquired a Kala Ubass. Going to be traveling and this allows me to bring a bass along. For local travel I have a pig noose 30. Reasonably light and runs on battery so I don't need to worry about the availability of a plug. The Pignose and most any smaller amp is still too big to bring on a flight. I was thinking of trying one of the mini amps. I know they don't do much, but might help the Ubass to be heard in a small jam session. Any advice?
