Query: Good info, even if a little bit outdated.

I found a lot of good information in the book, although it was written more than 10 years ago and technology has really advanced greatly in that time. Even so, some basic principals of sound and recording will never change and that's where this book was useful, espeically at the great price I got it for.The author also did a good job of explaining things in easy-to-understand language without a lot of technical jargon to bog it down. I'm glad I bought this book.
