Is anyone else frustrated with the Hartke 3500 head design, how the knobs stick out so far from even the amp they risk getting broken in transit? I even bought Hartke's amp head case, and its STILL a problem. I was a major problem when 2 days before a big gig, the volume knob busted off during transport. My volume was stuck at 3!!! I spend 4 hours fixing the stupid thing with CrazyGlue. Works OK now. But, if you are running into this problem, here is the quick fix: take some finished paper towel roles (the carboard inner ring), and cut them into smaller 2" rings. Place those over the protracting knobs each time you transport. Gives it enough protection. I'm just miffed that Hartke didn't engineer it better. I'm happy with my amp otherwise, but jeessh!!!
