Re: scooped mids question...
I think we also need to consider how much the mids are scooped and where. I like a slight dip in the mids, say that a Custom gives, my Maxon SD9 also does this. I think it sounds very natural. On the other hand, as Hames said, if you scoop too much out, it sounds hollow. Too many "middy" mids sound boxy. I like upper-mids and lower-mids.
Some pickups with a slight dip in the mids (Custom) sound better to me than pickups that are hollow ('59n) or mid-bloated (Custom Custom). As both guitars and vocals are midrange instruments, you need a slight dip to allow the singer to cut through when mixing. So I often end up cutting a small hole in the mids anyway. You have to experiment, but I get good results cutting at 1.7Khz, it doesn't seem to change the sound of the guitar that much. A narrow-bandwith cut, mind you, but it's enough to let the vocals show through. That means I can crank the guitars louder in the mix and keep up intelligibility in the vocals.
