In this post, I was given some tips on arranging electric guitars. However, I would like to do further reading on the subject (spreads, range, register, coupling, doubling, unisons, etc), and I can't find anything outside of the realm of jazz/big band and classical music. I am wondering: is there another stringed instrument (orchestral) that is similar enough to an electric guitar that I can use it as a proxy for an electric guitar? For example, if I study orchestration for "strings", would I learn a thing or two that can be applied to the electric guitar?
FYI, i'm working with a pop/rock setup--electric bass, two electric guitars, a vocal, and drum kit.
