So I'm looking at getting a new, lightweight 500w amp setup. What I have seen are the GK MB210 350w (500w w/ ext.) and the Ibanez Promethean 1X10 250w (500w w/ ext.). Both are about $600 and weigh 30lbs. I will end up getting an ext. cab no matter what (probably a 210) but am wonderring what you guys may have to say in regards to either of these little guys. Also, even if I have the ext. cab will the single 10" in the Ibby blow out if using the full 500w. Kinda' makes me wonder?! So how do they sound? I guess that's what I'm asking. Personal experience, as always is highly valued.
