Positive
price,headphone/speaker sim,morph control ,loop,wide range of driven sounds,metal switches and solid jacks and caseing
Negative
Reverb sounds fake,plastic knobs,limited control for the clean channel,dull sounding tubes which i changed and it made the amp "come alive "more,it may have built in tube biasing which is cool but that wont tell you how it sounds.
generaly a great deal,not really for the clean sound purist ,more a bedroom rocker that can get loud enough to annoy the folks next door or quiet enough without sounding thin.
