Feature:
High quality sound processer. Also has built in compressor, tho I don't notice any difference in the sound when it is activated.

Quality:
I have used this unit 3-4 nights a week and have had no problems with it at all. I would say the quality is there.

Value:
This mixer is a high quality reliable unit, but is is drastically underpowered for the price. I paid 579.00 for it new. Mackie advertises it at a 500 watt amp, which is true, but that is at 2 ohms. Its probably closer to 100 watts per channel at 8 ohms. There are many other reliable units with much more power and equal number of features for much less money.

Sound:
Sound quality is outstanding even when pushing unit to the limits.

Support:
have not had to deal with customer support.

Overall:
Nice features, good quality, just needs more power and a better price.

Feature:
The oversized cooling fins I think are a feature concidering I have used fan cooled systems and this runs quieter.

Quality:
So far everything is working as advertised. I do wish there was a quieter "break switch" though. It makes a pretty good POP when activated.

Value:
Good price for what you get. heavy duty little unit.

Desirability:
Unit looks good. i like the way it has the handle built into the side of it for ease of transporting

Sound:
Sounds ok. I use it with a recorded Bass and drum track at live perfrmances and it had performed ok so far. Wish I would have gotten the next size up though.

Support:
No comment as I have had no problem with this unit.

Overall:
I will gve it a 8 for overall.

Feature:
This is the first professional-looking powered mixer I'd used so I didn't know what to expect. I would have rated this section higher had it had the ability to provide separate monitor mixes (volume levels) for two guitarists. This model doesn't so I'll be looking to upgrade soon. If it had that ability, and was a bit higher-powered, I doubt I'd be getting rid of it so soon.

Quality:
No complaints about the quality.

Value:
I bought the thing used. For the price I paid (about $450.00) I'd say it was good quality. Like some other people I wish it had more power. Another reason I might upgrade.

Sound:
Sound seems ok to me. Though I believe the sound quality from my (acoustic) guitar has more to do with the quality of the guitar processor I use. But the Mackie does a good job of faithfully reproducing that good sound.

Support:
I've never had to use their service but I'll rate it high because I rarely hear from anyone who has had a problem with Mackies support.

Overall:
Other than not having separate monitor mixes, and it needing a bit more power, I'd hold on to it. As it is I need to look at an alternative for the reasons stated.

The only 2 real complaints I have are:
#1. This mixer has banks & is not individually potted (meaning, if you happen to break a nob off when moving the mixer, or it craps out, or whatever, you have to replace the entite bank/channel. Much more Costly than replacing just that pot (example -- Yamaha mixers are individually potted)
AND
#2. I've had problems with the 9 band EQ & sound -- Sound varies night to night, with no change in equipment (Taylor 814ce, Strat plus deluxe, Gibson LP standard plus, Gibson es175 archtop, Alvarez yairi classical, boss chorus ensemble, through 400watt JBL speakers) No change in placement of myself or equipment in the room - nothing is different. Rather difficult at times to get a clean sound (one night everything is crystal clear & the next its rather muddy & vacant sounding.
