Feature:
err, i think it has a bar in the back to push, wheels, and slide "rails".......

Quality:
seems great, i saw nothing wrong.

Value:
Its expensive, But i dont think its any more expensive than an ampeg......and trust me, it sounds SOOOO much better than an ampeg. Like, no comparioson....and 2000 watts of powerhandling.

Desirability:
OMG!! I'm trying to sell two basses, a guitar, and my current stack of SWR 4x10, Son of bertha, and a hartke model 5000 so i can afford this thing and the head....I LOVE IT!

Sound:
Ok, so i went into Sam ash to try this thing out.....I hooked up my bass(a Hartke starter kit bass with pretty much broken pickups,tuned to Drop C-G-C-F) Usually it only sounds OK but coming out of this amp it was beautiful!! sounded even better than the Rickenbacer i had tried through a mesa at a different store 0_0 It was loud, it had punch, and was well defined from my Low C up to my highest notes. Everything came out clear and not even a little muddy! and when i hooked up a Bongo to that thing OMG!!! it blasted out the bass, and shook me! unbelivable, i can't even describe it!!!

Ease of Use:
With the LH1000 head(which i was using at the time) it was so simple....had like 3 knobs and two buttons, but still sounded increadible! INCREADIBLE!

Support:
dunno, never tried....I called Larry Hartke once though. He was a cool guy, talked for a while and sent me some strings and a catalouge...Great strings by the way!

Overall:
Amazing truely amazing! thats about it. I kinda doubt i would ever need anything, Maybe get a Hartke Kilo head someday to make it sound better....
