Guitar On Hard: Zero To Rockstar is the book that I wish I would have had when I first got started. It is not an easy beginner book, it is all the stuff you need to know if you plan on making this a lifestyle. Most teachers teach guitar on easy mode. I do not. Instead of open chords, you will learn barre chords in the first part. If you just said "I'm good on that" or if you're a teacher who just said "Yeah, right", you are not who I wrote this book for.
This book is for anybody who is looking to dive deep. There are no shortcuts here. This is the long-haul, hard mode, grit based guitar book.
