Fender Jaguar

So I finally got round to trying out a Jag the other day in my local guitar store. I have to say, it was really nice. The tone was brilliant. I think it was a MIJ model but still....was damn nice.

My question is - does anyone know any sites, or just know generally, how the pickups work? There are 4 switches on the Jag, one is a killswitch, but i couldn't figure out what the other 3 switches did (ones located on the right hand side of the guitar, or bottom if you're sitting down playing it).
The two knobs (i'm guessing for tone?) didn't really seem to make much of a difference.

I am in love with this guitar but the fact it has so many switches that i can't work is holding me back - if someone could help me out that would be great, all help very much appreciated. I know there are lot of Jag lovers out there!
