Yes I've read about the old spec flat 50s you all were enthusiastic about 8), it even made me hesitate between the flat 50 and 52!!
I don't know exactly what I'll get, but Tim said it will be perfect!!! (I guess he knows his job ;) )
You'll get great pickups for sure, and as far as I'm concerned, Tim _really_ knows it's job - I even suspect he has some mind-reading superpowers. For the record, my own "first choice" for this telly was Piledrivers, and I was really surprised when Tim answered "BGF52s", decided to go for what the man said thinking "hey, there's this 14-days return policy you know", and never looked back.
I hope them to be powerful but pick sensitive, and just enought highs to cut through the mix.
powerful : obviously. Pick sensitive : I have yet to hear a BPK that is not (played : BGF52s, Brown Sugar, Slowhand neck and mid, TS bridge, Crawlers, RR, ABomb bridge, Mule neck). "cut through the mix": also depends on the guitar and amp, but with Tele pickups on a Tele I don't think you have to worry about this (neck pickup on a dark mahogany guitar can be a different problem).
I hesitated to put a p90 on the neck but I was afraid it'd be muddy, and I didn't want to rerout the body...
P90 neck on a Tele is a well known and proven choice, and I don't think a decent P90 could sound muddy in a Tele. Now the routing is another problem...
Do you know if the neck BFG50 is stratty too? Besides, it doesn't seem to be owerwound (DC = 6.8KΩ)
The very stratty tone of the BGF52 comes from the wire gauge and winding and while based on an historic (even if short lived) spec it's very unique to this model, so I guess the BGF50 neck will be more on the warmer typical Tele neck tone (well, listen to the clips...) - which is nice too when well done. FWIW, quite a few Tele lovers don't like the BGF52 neck that much because of it's "non standard" character.
Anyway: don't worry, wait until you here these pups in your guitar, chances are you'll just love them, and if not (really unlikely for the tones you mentionned but well, shite happens) you can just send them back. For the record, the only time I sent a BKP back was really my fault, the pup was exactly what I asked for and what Tim told it would be, it just wasn't what I really needed for this guitar - and FWIW, I was so impressed with the pup (RR bridge) I ordered another one (whole set this time) for another guitar where it really shines (icing on the cake: the neck is just awesome).
