Lots of this material was not only new to me, I was not aware that it existed, and I had not "thirsted" beforehand to know about (mainly) acoustic guitars. The author couldn't simply write a book about wood and gluing and the shiny glittering that make guitars lovely. That would be a simple "how to build a great guitar how-to book." Okay, that would work, and be used by a handful of luthiers and wanna-be's, but to make any non-fiction story interesting, it's all about the characters. St. John does that, and fairly well knits a somewhat otherwise screwball group of loafers and hanger-oners together with a brilliant and non-conventional master guitar builder. This book makes the latter famous, now, to a wide audience.
If I have one criticism, it's the cheap way Eric Clapton is used, almost as a ghost, to knit the story together when, realistically, there is no real story. Clapton appears to be almost totally disinterested in actually getting one of Wayne Henderson's masterpieces, and it's clear they are masterpieces, made the old fashioned way eschewing monetary gain for the most part, as well as any semblance of modern and/or productive processes of assembly. The book is very informative, if you can stand the long wait between the loafers and other strange pickers who wander in and out of the story as well as a very lame "Clapton" ending.
From a personal standpoint, I found great interest in the locale. Rugby, Virginia, of which I had never heard is quaint enough, I suppose. But in my early youth, my family and I lived for three or four years in Galax. Yes, that Galax, the town of the Galax Leaf (not mentioned) and the Galax Fiddlers Convention (mentioned). I vividly recall the area, with Independence and Hillsville and so on. That aspect made the book more interesting for me, and added to the knowledge gained by playing reader's dodge ball between the goof-balls hanging around and the phantom Clapton. But it was a good addition of guitar knowledge and appreciation of wonderful individual craftsmanship.
