Besides not having the metal dots on the pups.. what's the dif? Is it worth changing?
Depends on ones taste. I have 2 sss strats. One with stock pups, the other with 2 gold lace sensors and a SD at the bridge. There are different versions of the lace sensors, each with their own characteristics. Search them at Musicians Friend for a description. In my case, I love them, but also love the stock pups. The Lace's seem quieter, though I like the difference each guitar brings to the table.
