Nope!
Certainly NOT in alder.
I have a MM in an all-maple guitar, and it's fantastic!
It's true, i had two MM in a jackson RR3, and this was..... not good, middles were to smooth and basses were to tight, and the neck PickUp was twangy, totally contrasted to the liquid sound I search.
Now I have a tb 6 and a sh10 seymour duncan, better than the MM, but i think to change for a nail bomb(may be ceramic) and a cold sweat neck.
I think with mahogany, this will be awesome!
