Had a Blues Jr and never got on with it. I've owned tube amps (Blackstar, Fender, Mesa/Boogie and Peavey) but I really think at lower volumes solid state as the way to go. How about a Roland Cube (40-80 watt models - include chorus, flanger, delay, reverb etc, switchable channels and solo function plus a bunch of ok drive sounds). Stick it on JC Clean for super clean sounds. Then spend the rest on a really nice Wampler drive pedal: Euphoria, SuperPlex, Plexi Drive etc - you can honestly get some really tubey overdrive and distortion sounds out of a Wampler. Just another option.
