Feature:
Great features though, rear mounted inputs, front mounted knobs (perfect for use as an onstage monitor). 7-band eq was what sucked me in though - an excellent idea. It's the only reason I didn't go for the KC350 as a replacement for my current Roland amp. The Hartke amp does not mix stero, but I found that a plus for me since I only even monitor myself in mono. I also liked the rca inputs for ipod playback - nice feature.

Quality:
Knobs are small-ish, but feel solid. Eq sliders are metal (not plastic) and felt durable. I docked the amp a few points though becuase of the plastic corners. Something like this should have steel corners.

Value:
This amp is supposed to be on par with the Roland KC350, and is certainly priced as such. On the first day out of the box, it was noticeably inferior to my 8-year old KC300. 7-band eq is nice touch, but eq'd poop is still poop. I would recommend that anyone buy the KC350 instead (KC300 is no longer made).

Desirability:
It looks really sharp. My only asthetic complaint is the plastic corners (should be steel).

Sound:
This amp was to replace my 8-year old Roland KC300 (which has developed a slight warble). I had high hopes for this amp. But, it has a pronounced "hiss", one that you can hear from several feet away with *nothing* plugged into the map and all volume knobs at zero. Beyond the hiss, the amp sounded like a much smaller amp with that "inside a tin can" kind of feel. Could not eq it way. My Roland of 8-years sounded far superior (warble and all).

Support:
I've never dealt with Hartke customer support.

Overall:
I'm having big buyer's regret. I have a brand new KM100, but I still choose to take my ancient KC300 to my gigs. I will be returning it and buying a KC350 instead.
