"Stone and wood have a completely different micro structure. On a wood top the sound waves move along the wood grain much stronger than to the side. On a stone top the sound waves spread much more even in all directions making the whole top resonate with a long and even sustain. This is because stone has a dense molecular crystal grid structure while wood has an open cell structure. Mounting the bridge directly on the stone top with the strings going thru the Mahogany body allows a very strong attack and continuous and even sustain."
