American Deluxe Stratocaster

On the American Deluxe Stratocaster (and its left-handed, HSS, ash-body and V-neck versions), the S-1 switch functions quite differently than it does on Telecaster models, adding five more pickup combinations to the five already offered by standard Stratocaster wiring. With 10 total pickup wiring options then, S-1-equipped American Deluxe Stratocasters offer enormous tonal versatility.

When not in use, the S-1 switch doesn’t affect standard Stratocaster wiring, which is:

Position one: bridge pickup only
Position two: bridge and middle pickups wired in parallel
Position three: middle pickup only
Position four: middle and neck pickups wired in parallel
Position five: neck pickup only

The S-1 switch offers five additional pickup wiring options when engaged:

Position one: all three pickups wired in series
Position two: bridge and middle pickups wired in series
Position three: middle and neck pickups wired in series
Position four: bridge and neck pickups wired out of phase, with a special tone capacitor
Position five: bridge and middle pickups wired in series and out of phase, in parallel with neck pickup

If it's the right one, I'm guessing that I will have to rout the body a little deeper because of the extra length ...?

Also, do I need to get a different 5 way switch?
