Before gluing the back of the guitar,
I decided to show you an overall picture of the interior of the guitar so
that you can see all the bracing located on the internal face of the soundboard.
You can also see on these pictures small reinforcement bars stuck on the internal
face of the guitar sides. These reinforcement bars are made of mahogany wood
and are used to reinforce the guitar sides in order to increase the shock
resistance to impact which can occur on the guitar sides.
