i own a strat but i did a lot of modifications too it... i but in tripple humbucker and individul selection switches... as far as tone goes i made my tow tone controls master controls for all three pickups but used diffent capacitors to make one high and one low tone.. as far as adding a tone... i considering it... i considered using the volume pot as a third tone and putting a new volume in else where but i really couldn't find a place is was comfortable with... fenr guitars as built staunchily( the only rout out a little bit of room for pickups) and will definately require body owrk to fit another pot... the other complicated thing is that the pickups selectors are different from strat to strat... find the terminal where the pickup you want to work with is soldered to that swith and solder another wire there to make the positive end... then wire is and link is bakck to the signal reutrn... which iin your strat is pry on top of the volume pot... in case you want other mods i suggest you explore this site.... it is very useful www.guitarnuts.com/wiring/menu.html
