Gotta say, after a few days with my MB200, I'm loving it, and it has surpassed all my expectations. I figured on using it only as a headphone amp and for quiet practice, but it held its own in a full on jam session the other day, fighting against a loud drummer, vocals, keys, and two guitarists. The "GK watts are louder than X brand's watts" statement is definitely true! And it's so simple, light, and has the GK tone. Not a bad thing I can say about this head. It's already made some of my other gear obsolete. I won't get ahead of myself, but it's that good. I have mine mounted on my pedalboard since it's so small, and I wanted to have the ultimate portable practice rig in a box. Loving it!
