I have this set, RJ Fat Strat Noiseless, installed it in my Am Std strat before. my personal opinion:
1. Lower output than stock Am std single coils, parang same output level ng HS-2 dimarzio, but surprisingly bright sounding even with the stock pots. Not muddy at all on the lows.
2. wala kasing designation kung alin sa 3 ang pang bridge , mid , or neck, so mukang pareho-pareho lang ung set.
3. I dont get it why they call it fat strat, sounds pretty standard to me (not fat).
4. yep, noiseless, its a stacked coil design with adjustable alnico magnet poles (dont know what kind of alnico tho)
5. 1.5k per set of 3, so 500 isang pickup. di nga lang binebenta ng tinge.
6. Walang wiring diagram, 4 conductor ito e, but I found out that the white & black leads should be connected, then ung other 2 leads go to the vol & gnd, ala dimarzio.
7. no pickup covers, parang dimarzio virtual vintage blues. Love em or hate em.
8. kasya sa stock pickup hole pero you might need to enlarge a part of the hole if you want to raise the height of the pickup closer to the strings
9. no mounting screws & springs included, hassle.
10. fragile ung spool material kesa sa regular pickups.
I'm using them on a japan strat now, gig-tested, it's an ok replacement for standard single coils, sounds close to the original, with the same output level. Not for the heavy distorted sound, di kasi hot ang output. If you like a hot bridge pickup, mabibitin ka dito, better to pair it with a hot bridge pu, then neck / mid e RJ fat strat pus.
