some interesting points:
>p90s and most vintage tele pickups were wound with 43AWG; presumedly because the phat cat's bobbin is much larger, SD have used A2AWG. 43AWG is also commonly found in 'medium-hot' humbuckers, ie the duncan custom and dimarzio super distortion, where AWG is very much a PAF-type wire
>the metal cover on the phat cat makes it very quiet (for a single-coil pickup)
>the stock 2xA2 magnet set-up in the phat cat makes it too dark for some; as much as i love A2, i prefer the phat cats with 2xA5. they're not the best pickup for a first-time mag swap, as you have to lift the baseplate out of the cover and there's a chance you'll damage the coils' connections to the cable
>the phat cat kicks arse once you've got it how you like it (which may not be in it's stock form)
i've not owned a bluesbucker but have gathered the following info from pepole who have, and the DMZ site:
>the bluesbucker is basically an underwound 43AWG humbucker with 1 set of poles removed (the dummy poles are not magnetic and are cosmetic in function). so it's hum-cancelling but only has 1 set of poles; this is presumedly meant to make it sound more like a single-coil in the attack
>the bluesbucker has 3 skinny ceramic magnets, 1 on each side and 1 in the middle. i believe they're the same type as you'd find on the sides of a 500T or invader, but can't confirm this.
>the bluesbucker is supposedly quite good, from what i've heard
