hi, i recently bought micro cube about 2 weeks ago and pretty happy with it. I just recently got 100 bucks as a gift and planning on exchange the micro cube and get 30x cube so my question is that is there a significant improvement in term of sound quality between the micro cube and 30x. should i go ahead and do the exchange?

I'm pretty sure the Cude 30 has a lot more effects. Also you get to play louder, who doesnt love that? (your family/neighbours don't count)

louder and better sounding.
i have both, and the Cube 30 sounds a lot better. altho the micro cube is awesome for it's uses, so if i where you, i would keep it for the ocational "i wanna play rock in the woods" kind of stuff....
