(Edit: 4 things) I'm looking to get an under-$200 1x12 combo amp, most likely used, that would be ideal for the following things: 1) a good all-round practice amp. For both lower-volume living room jams with one, or two other people with no drums (or just a drum machine) and also loud enough for a full band practice with real drums if I don't feel like hauling my big amp setup to practice. 2) using as a clean amp for live dual amp setup Parked next to my 4x12 cab for dual setup, like how Joey Santiago of the Pixies does his live setup. 3) FX loop. 4) Headphones jack for silent practicing at home. My biggest question would be, should I go old-school and look for something like a Peavey Bandit, or Marshall valvestate, or would a newer modeling amp, like a Boss Katana, fit the bill more for all the diversity & options they have? I use a relative small pedal setup, but a modeling amp could be very convenient if I just want to grab-n-go. I'm willing to upgrade the 1x12 speaker if need be. If a solid state, how many watts?
