It's not unusual for players to have pickups changed out in search of "that" sound but not so usual to have reason to change them on a brand new instrument but this 50's Tele from Fenders new Vintera series came with a remarkably hot set,in particular the bridge which turned out to be reading over 9k....apart from some very early units while there was still some experimentation going on by Fender,real 50's Teles read from around 7k to 7.8K,dropping during the 60's to about 6.4k.
This Tele was to have a set of Fender True Vintage '64 pickups installed the preference being for staggered poles on the bridge which reads a more period correct 6.4k.These came in about 1955 around the same time the brass bridge saddles gave way to plain steel for a while before threaded bridges were introduced,therefore a set of these were to be fitted as well.Cloth wire and a bigger .047 tone cap would be used as a nod to a more vintage specific identity though the neck/both/middle switching was still a good way off 1956. As a final nod to the year a top hat was fitted to the selector,the small round tip having gone about this time as well.
The pickups certainly made a big difference,a clearer,richer tone both clean and with drive. It might be my imagination but playing the guitar unplugged both before and and after I felt the steel saddles to be giving a slightly clearer,more focused tone but it is a very marginal effect.
Overall a very pleasant and informative job and the sound is transformed.
