Bone and Ivory nuts and saddles have one inherent problem - they're made from organic materials, and therefore have inconsistent soft or dead spots because of their natural grain. TUSQ nuts, saddles and bridge pins are precision engineered under high pressure and heat, specifically to govern which frequencies are transferred to your guitar top (tone), and which frequencies remain in the strings (sustain).
TUSQ is consistent from piece to piece, and within each piece, to offer you harmonically rich tones without the problems associated with natural materials.
"TUSQ nuts and saddles have improved the sustain and clarity on all our guitars. We are using them on all our models." - Bob Taylor - President Taylor Guitars
