GraphTech Tusq Slotted 1 3/4" Nut for Acoustic Guitar PQ-6133-00

TUSQ delivers a rich tone, crystal clear bell like high end with big open lows and a significant increase in harmonic content and harmonic sustain. Increase harmonics equals more richness and character in your tone. Its the difference between a four piece choir and a twelve piece choir singing every time your play a note.
