Right basically i plan on building my own guitar with parts i picked myself,
i got 1 1970's strat body
1970's strat neck
1 bridge p90 pickup
1 Fender Jap pickup <-- middle
1 les paul neck humbucker

i am going to have a 5 way switch but what i plan to do is to have an additional switch that joins the p90 and humbucker together, is this easy ?
