I'm thinking of building a guitar for reggae - modding a mexican strat actually.

For the specs, I've been thinking:

alder body
maple fretboard
locking tuners
pickup change

I'm having trouble deciding what pickups to use, though. Anyone have suggestions?
I'm looking to get a sound similar to the one in the song Rastaman Live Up! by Bob Marley - http://youtube.com/watch?v=DelWKxMCM_o there's a link to it.

Also, any suggestions of other modifications?
what is the music theory and what does it teach you, like scales, solos, and to build speed???
