Work on guitar nut slots and string grooves with this guitar nut slotting file kit from TIKA. This nut file set is designed for compatible guitar nuts, saddles, bridge slots, and similar string instrument parts during basic repair, maintenance, and setup tasks. The file tools help shape or adjust string grooves on compatible acoustic guitars, electric guitars, bass guitars, ukuleles, and other string instruments. This set is useful for guitar repair kits, workbenches, music rooms, and instrument maintenance supplies. Check string gauge, nut material, slot width, and groove depth before use. File slowly and carefully, since removing too much material may affect instrument playability.
