Graph Tech PQL-6643-00 White TUSQ XL 43 mm Pre-Slotted Guitar Nut

Best for

A right-handed six-string electric guitar whose flat-bottom nut slot, finished height, 35.25 mm E-to-E spacing and 15-inch radius match the published 6643-00 geometry; often considered for measured Ibanez or PRS applications.

Who should skip

Skip it for left-handed guitars, mismatched slot dimensions or string spacing, curved-bottom slots, black TUSQ XL/TUSQ material requirements, or installations without the tools and setup skill to fit the final dimensions and slots.

Watchouts

Use official GTIN 702725247110 for the white TUSQ XL PQL variant—not retailer code 702727002083, white TUSQ PQ-6643-00 GTIN 702725120901, black PT-6643-00 GTIN 702725121755, or left-handed 6643-L0 identifiers. Ibanez/PRS fit is measurement-bounded, not universal drop-in compatibility.

Likely add-ons

Verify before buying

• Is the guitar right-handed and six-string?
• Is the nut slot flat-bottomed and compatible with 42.9 × 5.95 mm stock?
• Is 7.95 mm enough height after fitting?
• Does 35.25 mm E-to-E spacing match the original nut?
• Does the instrument require a 15-inch nut radius?
