Stone tone Blocks
These patented blocks are made of granite, and are designed to enhance and strengthen the sound of your tremolo-equipped instrument across the entire audio spectrum. Granite, when quarried in its natural state, is not only of an ideal density for the purpose of sustain, but also has a crystalline atomic structure which is ideal for sonic transference — it requires no factory processing or dilution, and the natural change in sound, upon installation, is so drastic that signal loss from the guitar to the amplifier will be decreased by at least 30%. The blocks are crafted from Volcano Black Absolute Granite, the compression strength of which is 19,000 psi/130,000 kpa and the tension strength of which is 700 psi/4,800 kpa; this is the 4th densest material on earth, just behind Diamond, Carbon and Quartz! Comes with stainless steel sustain block mounting screws.
