I definitely dug the vintage vibe I could get out of it. Had a nice, warm, round tone to it. When I rolled off the highs a little I could get a good, soft top end, without any tinny or harsh crap in it. I'm deciding between this & the GK MB115-II, which I'll test whenever the local GC gets one.
Either way you go you'll gave a nice combo. My MB112 is a great amp as well. Just a little different tonality from a GK than from a tc electronic.
