Essential reading and I would say the public interest!
This book will not leave me since I set foot in the violin.

It is extremely comprehensive and deals in detail with everything you need to know to realize his project to build a guitar or bass.

Having read other books of the same type, it is undoubtedly the best. On the one hand because it is written in French and very affordable, and partly because the Master Kamel is willing to answer any questions you may on its forum.
The second advantage is that it is connected with a spiral binding that allows really having to work beside you.

If I had to buy this book, and yes, sometimes twice a day!
So no hesitation, go for it, you will not regret it.
