These are modern Acoustics. They improved it and modernize sound. Depend what you are going to use it for. 30W is good for bedroom practice, maybe some acoustic set inside small room. I would rather go with 100W. New MKII is amazing little amp. Yes, it's more money. But, features are unbeatable for that price.
30W - 12" is not enough for me to punch in the belly. But, it does amazing job. Compared to others, it sounds equally loud like some other "toys" made in Italy marked with 100W tag. and 5 times more $$$$. If you don't believe me, go to GC and try yourself. Some of the stores over here, already know me. So, they let me try anything with "blue stripe"...with other available things...
