Please be aware, you have opened the "more options" section, which means your really getting into the customisation of the pickups - and thats fantastic! It'll really allow you to make the pickups your own, so wether your looking to make a set that matches up with a certain historic specification, or you' re trying to match a single pickup to another from a different manufacturer - this is the way to do it!
Its worth keeping in mind though, that with every tweak you make, you'll be getting further and further away from what we'd call the "standard setup", and as such, that means the pickups will come under the remit of Custom work
