Graph Tech PT-3834-00 Black TUSQ XL Pre-Slotted 4-String Bass Nut

Best for

Measured 4-string electric-bass nut replacements needing a black, pre-slotted, flat-bottom nut with 38.14 × 3.42 × 6.0 mm starting dimensions, 28.79 mm string spacing and a 12-inch radius.

Who should skip

Skip it when the existing nut slot or required finished geometry does not fit these measurements, when a curved-bottom nut is required, when a different string count or spacing is needed, or when white TUSQ is preferred.

Watchouts

PT-3834-00 is the black Black TUSQ XL variant. Do not substitute the identifiers for white PQL-3834-00 or PQ-3834-00. The manufacturer's Diamond/J/Fender-style family wording is not a universal compatibility claim; dimensions and final geometry govern fit.

Likely add-ons

• precision measuring tools
• fine sanding and nut-fitting tools
• qualified setup technician when slot depth or final geometry needs adjustment

Verify before buying

• Does the bass accept a flat-bottom nut starting at 38.14 × 3.42 × 6.0 mm?
• Is 28.79 mm four-string spacing correct for the instrument?
• Is a 12-inch radius appropriate?
• Is Black TUSQ XL the intended material and color?
• Can the installer perform final sanding and setup if required?
