Man I get to play a lot of guitars as I work on them.  Truth be told, I just have not been impressed with a lot of the pickups installed in the gutiars by the factory.   They often sound shrill, muddy, and unbalanced.   I just couldn't take it any longer so I made my own.    Started with the best parts money can buy, profanity. and a lot of determination.   After about 40 different trys, I nailed it.   Best strat pickups I have ever heard.   I will gladly put these up against any Fender Custom Shop Set.
