Hi, a while back I bought a bassman 50 with matching original cab for practice and recording purposes. I'm starting to gig now and find that amp is inconvenient to carry up and down stairs. Is there a possibly cheap 1x12 cab or something that I could use for these small venues with this head? I'm very new to this and don't know what to look for in ways of impedance etc. I would use my buddies little combo amp but the speaker just conked out.
