I have spent the night playing my MQ - just blues noodling, but it is just the most awesome pickup - it can go from mellow blues to hot Leslie West classic rock in milliseconds - the noise is, as the man himself says, about 50% of a strat (the noisegate built into my Vox AD30VT kills all MQ noise dead, but not the Strats) - it is bassier than the mule in the bridge (it would be, being in the neck) and somehow 'wider' in its tonality. It also has that single coil quack and clarity but nearly the same output of the humbucker.
All in all, everyone should have one. :D
