Independent shopping perspective
The Korena take
Graph Tech’s PU-6519-00 is a black TUSQ XL Un-Lock nut for a 6-string electric guitar with a Floyd Rose bridge and locking nut. Its 12-inch radius and revised slots are made to accommodate the strings at that bridge, while individual height adjustment lets you set the action to your preference. Extended ramps spread string stress more evenly for a smoother glide. For installation, sand the ends flush and use white wood glue; no guitar modifications are required.
