The image below shows our approach to V-bracing. The guitar is sitting in clamping fixture used to install the back which is not shown. All guitars after this one have the V-braces tapered from tail block to just below the sound hole. Our upper bout bracing ensures that the neck block can never rotate into the sound hole like the ladder braced guitars do. If I remember correctly, this guitar had terrible upper bout distortion. It is perfectly flat now.
