The invention discloses a bass neck convenient for mastering a bending deformation state and facilitating correction operation. The bass neck comprises a head, a handle, a finger board and a fret. The bass neck is mainly characterized in that a left upper end and a right upper end of the handle are respectively provided with a square long groove along the length direction, bottom ends of the square long grooves are provided with linear pigment layers along a width direction of a center line, front ends and back ends of the square long grooves are provided with screws, the screws are provided with penetration holes, front ends and back ends of steel wires respectively penetrate through penetration holes of front-end screws and penetration holes of back-end screws, head portions of the screws are designed to be a hexagonal head portion convenient for screwing a socket wrench, an end portion of the hexagonal head portion is provided with thread holes communicated with the penetration holes along axial lines of the screws, the thread holes are in matching connection with headless inner hexagonal bolts, and the steel wires and the linear pigment layers are parallel. The bass neck is advantaged in that mastering the bending deformation state is convenient, and improvement of quality and efficiency of neck correction operation is facilitated.
