Bone and ivory nuts and saddles have an inherent problem: they come from animals and are therefore inconsistent in their growth and cause soft or dead spots due to their natural grain. The TUSQ saddles, nuts 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 on the strings (sustain). TUSQ is made from 100% organic polymers, contains no oil or animal by-products and each piece is perfect and identical. TUSQ offers you harmonically rich tones without the problems associated with natural materials.TUSQ offers a rich tone, a crystal clear bell highlighting all frequencies and a significant increase in harmonic content and sustain. The more harmonics, the more richness and character in your sound.
