Barry,
I installed a Seymour Duncan "Jeff Beck Junior" in the Bridge of my '78 burst in the mid 80's, and it's great. The original had that "ice pick in the forehead" tone. I love the guitar, it has extremely nice timber and workmanship for a '78, w/ stock chunky brass saddles and a brass jack plate, gold bridge and bar. (Tuners are silver). I think it may be a special model.
Strung 13>.56, if you put your ear up on the horn, it nearly deafens you.

In my custom strat I had a Duncan JB Humbucker in bridge, Duncan cool rails in middle, and Duncan "opposed pole piece double stack humbucker" at neck(same size as a single coil).

I'm constantly changing the p/up's in this guitar, as well as the wiring.
I had a pull pot installed, so I can have all p/up's on together and various combo's. I also had a coil tap switch installed.
I had the Kinman in the middle, then the neck, but at the moment I have a Bartolini in the neck, and the coolrails back in the middle.
I've also messed around with polarity a lot.
I find the Bartolini gives me that beautiful clean strat neck sound, but it's a little bassy for O/D.
The cool rails is great for that quacky "out of phase" sound in the 4/5 pos, and also dirtys up well.
I've never been real happy with the Duncan JB Humbucker however.
I'm even thinking of replacing it with a p-90 (yeah, I know, I'm a nut).

I had a lake placid blue '64 L series back in the 80's w/ rosewood board, clay dots.
I had the board contour planed from the 12th fret up, as the strings were choking when bent.(yeah, I know, I'm a nut).
When I got it back home, I noticed the pole pieces looked like they had been sanded back(all shiny) and they were flat instead of staggered.
The penny dropped, and I went back to the shop, and he denied switching them.
I chased him around the shop for a few minutes but I couldn't catch him.
(He ran away out the back).
I've since heard that this sometimes happens.
I sold the guitar not long after and bought a Levinson Blade.
Active circuitry with treb/bass or mid boost.
It was a poorly made but expensive guitar, which sounded too good to be true.
After about a year I realised that it was a little too good (clinical sounding) if that makes any sense. (yeah, I know, I'm a nut).
I then bought my custom strat.
I do miss the mid boost though, and have toyed with the idea of installing a pre-amp.
The road to good tone is long and winding, and sometimes confusing.(Psycho-acoustics?).
