k definetely not a rails of any sort. no rails there for a start and it would be a dodgy output balance considering he has a normal tele neck pickup in there.
the cool rails is basically a lower out put hot rails. still got the 2 rails cept a much lower output.
i'd imagine the bottom is used for soloing since it's only got the bridge pickup but both bridge pickups look the same and i'm not sure if they're sensors either because you can see the pole pieces underneath which you cant usually with lace sensors.

is a good possibility. notice how the pole pieces aren't exactly bright metallic .... sounds like the tonal characteristics that richie would go for too.
