Peavey Micro Bass combos can be picked up for not much. I have one, and I love it for low volume home practice. Simple to use bass/mid/high EQ, no other nonsense. Great little amps.
I recently picked up a Line 6 Studio 110, which is nice too, but I like the simplicity of the Peavey and it sounds ace, to my ears. Like @BigRedXsays though… what sounds good to me might sound pants to you…. I went down the Markbass route assuming it would be amazing, it wasn’t, to me.
