I am new to lead electric guitar but have been playing acoustic for more than 10 years. I really wanted to get up to speed so I thought that I needed to 'master' EC first before moving further. And having bought this book, yes it is highly accurate and packed with all cream, derek and EC songs...it is very educational, I have gotten 5 songs down in 2 months. For beginners, to maximize this, one really needs youtube (guitar cover for the particular song you want to learn) and/or the audio track on hand. Pick a section (and I've learned one has to learn the solo's one section at a time), listen or watch, read tab, copy the lick, try again, listen or watch again, then repeat until you get it down. I've always been in awe of lead guitarists even in cover bands, but I've learned that you need to do it again and again (listen, read, cop, repeat, practice), no secrets to this.
4 stars since the binding may come off soon, the book is thicker than normal, so the book binding is a bit week.
