Graph Tech TUSQ pre-slotted guitar nuts are an engineered synthetic-ivory upgrade designed to improve tuning stability, maximize vibration transfer, and enrich harmonic sustain compared to natural bone or plastic.  

Key Features and Benefits

• Pre-Slotted Design: String slots are already cut (typically optimized for standard light gauge strings like 9–46 or 10–46), which saves considerable installation time. 
• TUSQ vs. TUSQ XL: Standard TUSQ offers bell-like highs and open lows, whereas TUSQ XL is impregnated with PTFE (making it super slick) to eliminate string binding during deep string bends or tremolo use. 
• Consistent Composition: Unlike natural bone or ivory, which feature random soft and hard grain spots, TUSQ is uniformly compressed under high heat and pressure for identical performance across the entire piece. 

Installation Considerations

• Slight Oversizing: Pre-slotted nuts are intentionally manufactured slightly long or wide so you can sand them down for a precise, custom fit in your specific guitar neck slot.
