Bone and ivory nut and saddle have an inherent problem: they come from animals and are therefore inconsistent in their growth, and their natural grain causes dead spots or dead notes. TUSQ saddle, nut, and bridge pins are precision-engineered under high pressure and heat, specifically to determine which frequencies are transferred to the top of the guitar (tone) and which frequencies remain in the strings (sustain). TUSQ is made from 100% organic polymers, contains no oil or animal by-products, and every piece is perfect and identical. TUSQ offers harmonically rich tones without the problems associated with natural materials. TUSQ delivers a rich tone, a crystal-clear chime that highlights all frequencies, and a significant increase in harmonic content and sustain. The more harmonics, the greater the richness and character of your sound.
