I own 2 of these basses. One is strung with Fender 9050L flatwounds, the other with Ken Smith slapmasters .40-.95
Both are built very well IMHO. I'll go point by point on these on why I like them;
Lightweight!!! Big consideration for me when getting a bass nowadays. I like Fenders, and have owned many in the past, but they're just too danged heavy for my taste.
I like passive pickups, so no disappointment there. When you turn both pickups to the same level, they do cancel the hum. A lot of times, I just use the neck pickup. Still quiet. They sound punchy, and have a good clarity. 6 of 12 new tracks on my band's son to be released CD were recorded with these basses, and they sounded really nice! No complaints.
The input jacks are solid! One bass is 4 years old, jack is still like new! The volume and tone pots feel really good, and no buzzing. Can't say that about most Fenders I've owned. I once owned a Yamaha that was even worse!!!
The necks feel really good, and you have 21 frets standard! Fender only offers more than 20 on deluxe models, and you'll pay a lot to get those (I did own 2 of those so called "Boner basses" back in the early 90's-they had 22 frets, but I absolutely HATED those things. I don't miss them one bit.)
I did two things to each of mine;
Put on Fender vintage jazz bass type volume and tone knobs. I like having the white lines, and they are a bit lighter than the stock metal knobs.
Both got Hipshot ultra lite tuners. One had plastic imitations of Gotoh GB-7's. The other had metal tuners, but with plastic bushings. The ultralites are very precise, and lightened up one really well.
If I have to complain about anything, it is this-no fretless option!
I've never played a USA Millenium, so I can't comment on those versus the BXP. I have no doubt that the USA's are superb instruments.
IMHO, for less than 300 bucks, you get a bass that sounds good, plays good, looks really nice, and won't break your back!! Not a bad deal. I wouldn't discourage anyone from buying one
