I had the CS 54' on my 50th anniversary Strat, I decided to change them after comparing them to a set of trilogy pu on another Strat, even though they are not vintage, so I spoke to Tim looking for a vintage pu that would best represent the 54' 50th anniversary Strat, he recommended the Apaches stock wound on 2 & 4 th position not RW/RP. Best tone ever!!! In comparison the 54' were dull in every aspect. One characteristic of BKPs is they are open sounding and you can actually hear the different notes being play rather than putting a blanket over your speaker! There is an excellent article under the reviews and award section I think!
