Put the Yardbird neck in a Fender custom shop 62 and it's a great improvement. Compared to the stock 63 pickup there's more volume and body to the sound. The 63 is more airy and sparkly ( very good sound) but is thinner, Yardbird is more dynamic and bluesy. I reckon it has more mids in it but still very clear. Funny but I can hear a similar character to my BKP90's.
So now I'm thinking about the bridge of course. Again the 63 sounds great but I would say is a bit on the thin, bright side. I'm wondering whether to go with the Yardbird or The Staggered 55 'cause I like the string balance with the staggered poles. Any opinions on these two?
