I'm looking for the smallest, lightest one-hand combo for coffee shops, art galleries, and receptions. Quiet background music only, no drums, just jazz guitar and bass. It must weigh less than 20 pounds, as I have difficult back issues and travel by taxi or rideshare. Is the Micromark worth $300 more to save a few pounds and 2,000 cubic inches? Can that tiny amp fill a coffee shop or art gallery lobby? Soundwise, I'm partial to Fender, as I've owned a few. The only Markbass I've tried was years ago, a JB 1x15 combo, which was just OK. The Micromark is not available locally, meaning I'd have to order online and cross my fingers. It's already the max I'd care to spend for these occasional gigs, so I'm leaning toward the Rumble 40 even though it seems bulky for its speaker size and power rating.
