I am not sure if you can play with the app when it doesn't have a connection to actual pickups. You can always download it and see if it works. With humbuckers, you have some choices:
Humbucker pickups can be assigned as:
• Standard Full (grey both coils, slugs highlighted both coils, as shown above): coils in series in standard wind direction
• Standard South Coil (grey south coil with slugs highlighted): split to south coil of the pickup, normal wind direction. For most humbucker models, the south coil is the coil with the screws, sometimes referred to as the adjustable coil. The south coil is usually closest to the neck on a neck humbucker and closest to the bridge on a bridge humbucker.
• Reverse South Coil (blue south coil with slugs highlighted): split to south coil, reversed wind direction.
• Reverse Full (both coils blue): coils in series in reverse wind direction
Standard North Coil (grey north coil with slugs highlighted): split to north coil of the pickup, normal wind direction. The north coil of most humbuckers is the one with the slugs, and is the farthest from the neck in most neck humbuckers, and is the furthest from the bridge in most bridge humbuckers.
• Reverse North Coil (blue north coil with slugs highlighted): split to north coil, reversed wind direction.
• RP (gold): Coils out of phase in parallel. Coil starts are hot.
• PRP (green): Coils out of phase in parallel reversed. Coil finishes as hot.
• Off (black)
