Feature:
The controls they give you provide a wide array of possibilities for sound. You can fine-tune it to you particular taste pretty easily.

Quality:
Product seems to be of very good quality. I got a maroon one, just looks astounding. Feels as if it is built pretty sturdy, and a nice weight to it, not too light, not too heavy. Everything is smooth and curvy, and I love the head. I've only had it for a few months now, but the only problem I've encountered was having to replace the batteries that came in it (nearly had a heart attack, thought the thing screwed up, but was perfectly fine after replacing them). I also have an Ibanez SR300DX I got before this, paid almost as much as for this Peavey, and the Peavey easily blew it away.

Value:
Pretty low price I think for a very nice bass.

Desirability:
I don't know about everyone else, but I love the shape of the body. The P-bass design with the elongated, slender horns, and the head is fantastic. The maroon color is beautiful, makes me want to get another to just see how good the other colors look.

Sound:
Pretty good sounding. Nice and quiet when needed. Can use the control to adjust so you can have mega bass or, if you want, adjust so that you can get a more guitar like sound. Nice and solid overall, works good with rock and alternative.

Support:
Haven't had to deal with the company yet, hope I won't have to. Seems like they'd be pretty easy to deal with though, easy links up on the Peavey website. You can also reach their manuals online too (I either lost mine or it didn't come with it, I'm not sure), but I was able to download the one off the internet.

Overall:
Well, I'm already looking for other basses, but that's because I'm a collector. I want other basses in addition to this one, just to get a view of other brands, other styles, etc. I'd say, comparing this with other basses I've looked at, it might not be the best out there, but it is sure damn good for under 500 dollars. In the event that it ever got lost or were stolen, I would definately go out and get another Millenium AC 4 BXP.

Quality:
The finish is awesome. And if you're not bouncing it off someone's head or using it to chop lines, I'd say it'll last quite a while.

Value:
I think it was a great value for a back up bass.

Desirability:
That's the beauty of the Bass. It's practical, very playable, affordable and the finish is very hot. I have 7 basses, some worth a lot (3 @$1700.00+) and the playability of my Peavey rivals 2 of those high end "boutique" basses. It's very comfortable and player friendly. I have played an entire gig with it and when you're used to a Music Man or a Tobias it's a nice feeling not to have a coffee table on a guitar strap.

Sound:
I PLAY IT THRU A Peavey 700 watt fire series head and 4x10 and 1x15 for cabinets

Ease of Use:
I have no problem with this bass. I can make it thump or shred all day. And it's as clear as a bell.

Overall:
The guitar serves its purpose well. Would I buy another Peavey bass? Yes, now that I know the quality of the brand. If the $300.00 bass is this much of a value, I would consider the high end basses as well.
