I noticed a surface crack on the soundboard of my older L&H Troubador today (see photo). This instrument had been sitting idle for a long period of time and I have been gradually bringing it back up to pitch. The surface crack runs from about 4G to 5B, and there is no sign of the crack inside the body. I had planned to replace all the strings soon.
Any advice on the best way to manage this? If the worst happens and the soundboard fails is it cost-effective to pay for the repair?
