TUSQ Nuts:  FenderEpiphone

TUSQ If you have a high quality acoustic or vintage guitar you owe it to yourself to hear the difference a TUSQ nut and saddle will make. 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. Bone and ivory have hard and soft spots (grain), throughout each piece, hampering consistent transfer of vibrations to the guitar top.
