I can't think of much of a reason why this wouldn't be the amp for me... I have always loved GK amps, so the tonality and volume is what I like. My current rig is an MB500 on an Aguilar 2x12 cab (4 ohm), and while it's not ultra-lightweight or one convenient package, it's certainly manageable. And I'm keeping that, too, so it's not being replaced. The MB212-II combo is the same 500w, same essential head-unit, 41 lbs and smaller than my other rig. It's going to end up cheaper than a head+cab used that I could buy and more portable (even though it will likely be a practice spot rig mostly). If you have any slings and arrows to turn me off of it, I'd love to hear what they are. Or, if you know this is going to be what I'm after, please help cement my love for it!
