This edition has been updated for 1992 and includes a learning programme, a chapter on performance technology, guitar maintenance, repair and customizing. It also highlights the innovative techniques of over 20 world famous guitarists.
My dad owns this book, and I have read and reread it, trying to absorb all the information it holds. Of course it holds too much info, and I can't remember it all, so every time I read it, there is something new. It has every thing a guitarist would want or need, plus more, so even the nonguitarist would want it.
