I can never put it at full volume because it would just be way too loud for my room and house. So I'm not using the full potential of the amp. Plus it's a pain to have to carry around.
I bought it because I got an unbelievable deal on it. Around $400 brand new.
I would ask you what exactly you plan to use it for. If it is JUST for having it in your room to practice and learn on, then go for the 112. If you plan on taking it and playing live gigs or playing with a drummer, then go 212 because you'll need the volume. For a beginner, I don't see you needing a 212 though.
Don't let your wants take over your needs.
