Feature:
I love the 4 channels that give me plenty of options, the XLR I use for vocals, the built in DI for the sound board, and the pre-amp equalizer.

Quality:
I've had it almost 4 years now. Carried it everywhere. Dropped it more than once. It is heavy though so I put wheels on it. I would like to see it lighter. I would like to see it wedged a bit like a monitor amp, or make it tiltable.

Value:
Yes indeed.

Desirability:
Form follows function.

Sound:
It's been great for my needs. I use it for my acoustic playing, electric playing and bass guitar playing. I have effects boxes for each type of guitar so the flat response of this keyboard amp has worked well. It has not colored the sound. I use it for stage monitoring mostly although it has been used as sound reinforcement too. I also use it at home for practice.

Support:
No experience here except the user manual was friendly.

Feature:
Love the built in DI box with attinuator! I use as an amp for electronic drums, but have also had three vocal mics as a practice PA, and it is clean!

Quality:
It's kinda large, and without casters is a real beast to carry.

Sound:
This amp sounds great. Clean, powerful.

Ease of Use:
Very easy interface.
