A bracing system for acoustic stringed instruments with a hollow body, a body wall, a sound board, a neck, a bridge and a bridge plate, the bridge and bridge plate placed on the top and bottom of the sound board, the bracing system comprising: a. an upper brace near the neck affixed to the inner body wall of the stringed instrument; b. a lower brace affixed to the inner body wall near the tail end of the body; c. two or more longitudinal braces, one end of which is attached to the upper brace, and the other end attached to the lower brace; d. a means for reinforcing the bridge that provides leverage against the instrument's bridge plate, which acts to counteract the direction of force exerted by the instrument's strings on the bridge; and e. two or more rods, one end of which is inserted into the upper brace, and the other end inserted into the means for reinforcing the bridge, in a manner such that the rods sufficiently withstand and counteract the direction of force exerted by the instrument's strings on the bridge.
