Bill Foley's seminal work proved very helpful for me. One could not ask for a more complete text on building a custom electric. I got into guitars and found that the beauty of the construction was something that I had to learn more about. This book gives instructions on how to assemble your own custom axe from popular manufacturers' assembly-ready guitar parts. And even if you aren't going to make your own, buy this one to learn all about how the different parts work, from standard pickups to humbuckers, from tremolo and tonal controls to passive, noiseless pickups. The advice he gives also helped me choose specific components for my guitar, and then told me how to put it all together. Although it is out of print, try to order it through Amazon's Out-of-Print service, which has helped me in the past. A must for a guitar lover.
