I haven't really got a handle on the differences between the various BKP Tele neck models, but I know the type of wire makes a difference. I kept a note of this comment from Tim:
Tele neck coils are amongst the smallest of the single coils and traditionally wound with 43 gauge so always sound warm no matter how you wind them.We now make the Blackguard Tele Series necks with 42 gauge as per the original '52 spec-these are much brighter and cleaner than the 43 gauge necks so you've got plenty of choice in the range.
Personally I
like a really warm-sounding Tele neck pickup,
without too much definition, so I guess I'd be looking for something with 43 gauge wire. Don't know which models that would apply to, though.
