The bass just feels right. For that price you get solid 3-band EQ preamp, which is also equipped in Sire's higher version M7, except two humbucker split toggles.
Also, compared to elder M7, HH set is different, but taking into account that M7 has those split toggles, perhaps that's the only difference that these two set s have (in frames of sound).
Last difference is bridge (in these two models), where M7 got a better one, which lets you to tune it more precisely.
That's it. Other than that it's a matter of taste and wood combination preference. Just guided by these 3 differences I can state for sure, that M2 deserves a good review having most of the benefits of elder's version (which is twice the price).
I've jumped in to the bass from LTD B-404SM (which is still with me of course) and I may say M2 is decent and can stand in line with my oldie LTD. LTD equipped with Aguilar soapbars and MikePop FlexCore pre-amp and of course variation of sound you can get out of it is way more bigger than from M2, but M2's own pre-amp impress at least a half of tones you can get out from it. The "out-of-the-box" sound is pretty warm and full of sustain. Lack of attack is noticeable, but can be compensated by pre-amp tune for genre you play.
If not talking about the price, here are mine pros & cons
Pros:
1. Amazing pre-amp which would suit variety of genres
2. Build quality + color finish. Looks fantastic and pretty modern
3. Easily comparable with elder's versions.
Cons:
1. Lack of attack out of the box
2. Generic bridge. I have not tuned it yet for a week I have the bass (except the day it has been delivered), so can't complain much, but I guess there may be some issues tunning it precisely for someone :)
3. Plastic pre-amp knobs are made not so good.
I can recommend this bass to anyone.
