Marcus Miller M2 5 TBL 2nd Gen

I just received a Marcus Miller M2 and when I tried to adjust the truss rod I saw that the nut was completly worn out!!
no way of turning left or right.
I am assuming that this isn't Thomann's fault, but the thing is that I have to send it back and wait for the replacment one.
Bottom line, if I was satisfited with the set up of the instrument (as it came from the factory) I would have a bass guitar with a permanent problem of adjusting the neck ,down the road ...
Besides that the sound and over all instrument is nice.
I would suggest to everyone else who is interested in this bass guitar to be very meticulous whith the details, or the function of the product becuse in this price range the quality control is really poor!!

2 weeks Later...

FINAL OPINION:

Today I received the replacement.

CONS:
The bass needs a very meticulous inspection before buying.
The tuning pegs and the fretboard nut are the first upgrades you should do.
There is also an Allen Key which comes with the bass , and is supposed to set up the truss road with it!
BE CAREFUL with that, because is not the right SIZE for the truss road,OR the factory uses the most horrible truss road nut I' ve ever seen!!!!
It's unacceptable!!!...
If you want to adjust the truss road you have to be extremely careful with the given tool, or any other tool because the truss rod nut is not a perfect fit as it should be....somehow it fells cheap, and worn down from the beginning .
The Main volume/ tone knob and the mid frequency knob are turning each other when you try to adjust them but it's an easy fix...
The bridge is ...."ok " you could say that ,it does the job.

PROS:
The Pre amp of the bass is really nice and it gives you a lot of options.
Also the pickups for this price range are nice.
Frets are smooth and even through the fretboard.
The paint job also is ok for this price range...
of course if you trying to find small imperfections you will see them.
In my case is almost not noticeable.

Over all it's a nice "first" bass guitar, which lacks in quality control and it sounds nice because of the pre amp .
Hope that I was helpful .

First impressions out of the box - it looks and feels great. I really like neck profile, it is kinda rounded and feels really nice (for me). Actually I think it is the most comfortable 5er I've ever played. Transparent blue finish looks really nice.
Quality - well, not so great. Few painting defects around the edges, plastic knobs are just awful, finish is really fragile and chips easily. Pickup cavities is so tight that you can't event get pickups out, not mention change pickups height! So prepare your chisel for that. It had few high spots on the frets. Also nut slot for A string has been cut too low.
Sound - didn't really like it, maybe just not my kind. Of course it has a lot of features, like active preamp with parametric EQ, but I found it really not that usable. Frequencies bandwidth is unnecessarily wide, so boosting low end, for example, makes it mutter. In fact, I liked it the most in the passive mode.
All in all - it is a decent bass. It required full setup (including fret leveling, fret end dressing etc.), but after that it plays really great. As for sound - well, it is a matter of preferences after all. IMO not really great.
