Graph Tech Black Tusq XL groove PT 6116-00

Dimensions: 43.36 x 4.88 x 8.4 mm pre-notched. String spacing: 36.45 mm. Radius: 12. Suitable for many electric and acoustic guitars. Black Tusq XL is a specially developed material that intensively transmits the vibration of the strings to the neck of the guitar, enhances overtones, and overall makes the sound fuller. It is based on the highly resonant Tusq material but is additionally coated with PTFE. PTFE is an extremely slippery substance that prevents the string from getting stuck in the nut, resulting in significantly improved tuning stability.
