GraphTech PQL220000 TUSQ XL Self-Lubricating Blank Nut, Fender Style, Flat Bottom

Sounds so good it must be illegal! Man made ivory. Compared to standard materials, you'll hear crystal clear bell-like high end, big open lows, and a noticeable increase in overall sustain. Unlike natural materials such as bone and ivory, TUSQ is consistent from piece to piece. Without a doubt, this is the best synthetic material on the market, and it cuts and files beautifully.
