GRAPHTECH Acoustic Saddles Slab

TUSQ transmits the right frequencies from the strings to the top of the guitar, resulting in a richer, fuller tone.
Makers and players of guitars agree... TUSQ man-made ivory brings acoustic guitars to life. TUSQ simply transfers vibrations more efficiently to your guitar top, producing huge open lows and crisp bell-like highs.
Bone and Ivory Nut and Saddles have one flaw: they're constructed of organic materials and, as a result of their natural grain, have inconsistent soft or dead places. TUSQ nuts, saddles, and bridge pins are precision engineered under high pressure and heat to control which frequencies are conveyed to the top of your guitar (tone) and which frequencies remain in the strings (sustain).
TUSQ is uniform across the board and within each piece.
