I have the Holydiver and I wonder how the MM compares to the HD tone-wise....Lows-low mids-high mids-highs, tightness etc.
I had them in the same guitar (a brazilian mahogany les paul with imbuya top and brazilian rosewood board)
miracle man definitely had a deeper bass, sharper top and less mids (the guitar was still very mid heavy, though)
low end was huge, but very solid
the holy diver was fatter in the mids, more balanced low end, but looser, and with rounder top
hard to tell which one was better
the result will depend on the woods, body thickness, neck joint, amps...
I wouldn't install a miracle man in alder, but you're using mahogany, basswood, spanish cedar or korina, it will probably be a good match
