CF Martin owners tend to be a club who know what they like. Put them in a music shop, like Vintage and Rare (Bath or Denmark Street, London), Hanks (Denmark Street) or Farnham's Guitar Village and they are in paradise, speaking a language of their own (when they're speaking rather than playing).
Buying a new guitar (or just popping in to try a few for the future) can be a life-changing moment not to be taken lightly. This book is an excellent companion for Martin owners and prospective buyers.
This is a comprehensive and thoroughly enjoyable book for the enthusiasts in which they will see many of the great Martins and the developments and extensions of their designs, as well as details of their body types, serial numbering system, thre technical details of guitar production and everything else needed to appreciate the guitars.
An excellent read.
