I knew absolutley nothing about live sound before I bought this book, but now I actually have some knowledge of it. Its a great book for newbies, but don't get it if you've got even a moderate amount of experience setting up PA systems. Now that I've read it I really understand how to wire, test, and run a small PA system. My only gripe is that it doesn't go to in depth on miking drums, which I kind of hoped it would do. Then again, for most small venues, drum mikes aren't necessary. It also spens a lot of time on feedback control, which isn't a bad thing, it just seems to be one of the main focuses of the book.
