Description:This book doesn't even mention active pickups or noisefree single-coil pickups. It lists about 20 major manufacturers, of which I'd only heard about maybe 5 of them, and then I'm a gear head. Of course basic electronic principles haven't changed since this book was written but come on. I generally don't agree with folks who say "you can get all this information on the internet" because there's a value in having everything carefully preselected and gathered in one place, but this book is so dated I would recommend people to use google instead. I regret buying this.
