I don't play stadium shows, so I see that this head is rather good for my purposes. The EQ works really well, and when I'm playing in small events like weddings and bar gigs it sounds good. Kicks just right with my 1x15" and 4x10" cabs.
I have never had any problems with it, quite opposite. It has been running nicely and not a knob has broke.
If however I could change something, I would make the handle somehow different. It's way too small.
Overall I think it's good head for it's price.
