Hi, i happen to be an owner of this book as well, the revised edition i bought from borders. personally i dun find this book good enough, but then again i dun think u can find better ones out in the market. it has lots of detailed information, but it isn't structured in a comprehensive way. rather all info are lumped in huge chunk in the sense that when u wanna look for something, u need to go thru all the long-winded paragraphs.
i find lots of times we can find better, more comprehensive info on net, like if u need a guide to adjust your "truss rod" and u type that in yahoo and boom, there u'll get lots of info.
