duncan doesnt make anything like that, though the custom shop might be able to. i dont recall them being all that great the one time i played a guitar with them.
from jason lollar:
I cant tell you what they sound like, they are not common enough that I have run into them installed. I only get them in the mail.
A.W says they sound good but different than a 90.
I can tell you some specs on the 6 string version, the magnet appears to be alnico 2 and is .27 thick by .77 wide by 2.25 long. Thats about 3X the size of a PAF magnet
Not many turns on them probably 44 gauge. I dont know anyone that can re-wind them, I have called everyone, Lindy, Seymour etc.
Its sort of like taking a strat coil and laying it on its side.
I have made some single coils like that with bar magnets and they sound more compressed than a convention coil/magnet structure and lack zing on the top end. sort of humbuckery sounding in a way.
The only other pickups I recall being made similar to these are a couple Gibson bass pickups and the sidewinder.
