The Seymour Duncan SSL-2 delivers vintage sound without the usual problems with unbalanced volume of the different strings. When the typical staggering of the individual polepieces was developed, the G string was generally wound and correspondingly quieter. With modern sets of strings, however, this results in an overemphasis of the thick blank G-string - not that tragic, but audible and disturbing under certain circumstances.
Otherwise - as said before: Vintage strat sound; what more do you want?
