Further research is backing Ben's call on the MMs. However some say the cleans are poor. But then, you can't have one guitar do it all and I'm looking at creating a doomed out metal axe with some real grind at high gain. I have a Strat and R7 for cleaner stuff.
Some use a different neck pickup (CS, Mule....others?) for some clean action, but maybe a set with two different pickups creates balancing problems. A calibrated set of the same pickups might work better and be more evenly balanced. More predictable result? Though it sounds good if you couldhave a brutal bridge and a sweet neck.
