Here's my entry to the club...
I have a 2002 20th Anniversary Squier P Bass that I did some work on last weekend. I installed a Fender Original pickup, replaced the pots from the unmarked ones that were in it to CTS (I also put on the Fender P Bass knobs) and put in a Switchcraft jack. I also decided to have a bit of fun with a mod, so I put in a switch that would let me select between .1uf and .047uf capacitors.
Since I'm sure you all know what a black Squier with a white pickguard looks like, I'll include some more interesting pictures.
The pots/caps/switch wired and ready to be put back in:

With the upgrades the bass now sounds amazing!
I have one question though... Since the pickguard has 13 holes, will a regular 13 hole P Bass pickguard fit? The plastic is very flimsy and flexes when I take the cord out from the jack so sooner or later (probably sooner) the pickguard is going to break. A white or red pearl pickguard would look great!
