GraphTech PT606000 TUSQ XL Black Self-Lubricating Slotted Nut, Epiphone Style

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.
