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?Çöit 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.

“I couldn’t play without a Stone Tone Tremolo Block now that I’ve started using them. It’s like icing on the cake”. -Chris Poland (Megadeth, Ohm)

Ground?áStrip Information

?á

For those of you who have single-grounded?áelectronics in your guitars, we?ÇÖre now including a .020 copper?ágrounding?ástrip that’s recommended to be installed between the StoneTone Rock Block and your baseplate to counteract any possible?ágrounding?áissues. A few users have experienced buzz in single-grounded?águitars after installing a StoneTone block, especially if the only?áground?ápoint on the guitar was at the tremolo claw, but were able to easily nullify it by adding this?ágrounding?ástrip. While this isn?ÇÖt a particularly frequent problem, it is recommended that you install the strip on single and rarely double-grounded?águitars with your block merely as a precaution, so that if you experience buzz or hum after installing your StoneTone block, you or your trusted tech can easily run an extra?áground?áfrom the tremolo claw?áground?áwire and solder it to the strip, after which your guitar is guaranteed to be quiet. If your guitar is triple-grounded, you can disregard this precaution.
