Just for the record I too prefer books, and have my share as well as I have run off every usefull tidbit from as many links as I feel are use full now or maybe in the future.
I staple corresponding info together in sections, ie: hum/single/hum configurations, strat setups and mods, etc, etc........
so the stuff I find usefull can be in front of me during build/setup/wiring senarios.......... :icon_smile:
I have ( Guitar Electronics, By Donald Brosnac ) which is dedicated to wiring, but to be honest with you, I find it really weak compared to the Net............but from a beginers stand point it can be usefull in understanding different stuff.
