If you hate backaches, awkward carries and being drown out by a drummer MORE than you hate being poor, maybe try: TC electronics bam200 amp plus an ampeg svt 210 vertical cabinet. I’d even be willing to roll the dice on a tc electronic 2x8 cabinet, though it would be bit of a gamble on volume. The TC amp head is inexpensive, tiny and can be dropped in your guitar case or a big coat pocket. The narrow cabinets I’ve listed are lightweight and easy to carry. I suspect the only things that you could find used on that list is the svt 210 cab. More criteria failure, I know, but just trying to help.
