Gentlemen - I purchased an RS kit when I bought some WCR pups a few weeks ago. My results are consistent with that of the members of this forum, and I am considering upgrading some others guitars. The guitar that was upgraded was a standard Lester. My next favorite guitar is also a Gibson, but is a historic model. This Lester speaks to me. I can only imagine what a nice set of Fillmores can do to my baby. The question is this. How much better is the RS guitar works kit than the Gibson kit (with the bumble bees) that is currently in there? Also, how does it impact the tonal qualities of the guitar? If anyone has changed to and RS guitar works kit, but left the pups of your historic unchanged your input would be valued as well.:RoCkIn Thanks for your help.
