I'm looking to upgrade my current amp, I have a Peavy Envoy 110 which has the transtube technology to play with my 2014 Gibson SGJ. Lookin for a price range of around 400$, playing mostly AC/DC, Metallica. Most important factor would be sound quality/tones. I don't need something loud since it will be pretty much only playing in the living room and not planning to play in a band with it. I was looking at mircro terror or marshall dsl1cr but would be open to any suggestions in modeling amp too.
