What a book! Worth having for the close-up of Clapton's Cream psychedelic SG on the cover alone, never mind the reams of pages of photos inside detailing practically every guitar ever made, plus those bespoke axes owned by the likes of Jimi Hendrix, Rory Gallagher et al.
There are pages on guitar assembly and crafting, and after making one at school 45 odd years ago now, I wish I'd had this book as I'd have made a far better job of it.
Sections on different styles of acoustic guitars, the above on electric guitars of all shapes and often some quite odd ones, too, amplifiers, effects pedals, how to string and adjust the instrument; everything you want or need if you love the guitar.
If you prefer just looking at guitars rather than owning and / or playing one, for the price, this is a knockout coffee table book which will create talking points with everyone who picks it up and flicks through the 600 or so packed pages.
