Good question, F30!
When I first joined LTG, I quickly learned that the most-often mentioned reference was "The Bible" -
The Guild Guitar Book by Hans Moust. At that time, it was out-of-print and fairly hard to find (unless one could find a used one at a very high price). Luckily, it is in-print again and
easy to get for about $30 at Amazon. As Ralf mentioned, we are all waiting patiently, if not anxiously, for Volume II. Please, Hans, give us a bit of good news that there is a target release date? :::::imploringsmile:::::
The Gruhn and Beesley books are OK, but I much prefer Hans'.
However, the best, best-ever source of all things Guild is LTG. There is someone, somewhere who owns, has owned, has played or knows about every Guild made. I'm always astonished with the info LTGers know about Guilds. Just ask. LTGers are so willing to help and provide info. :wink:
P.S. The Guilds of Grot (Kurt) is our own Guild museum curator. His collection of Guilds and memoribilia is second to none. He's the best!
