Specifications ◆ Model Name: FGR-1 ◆ Finish (Color): C / Chrome ◆ Type: Locking Nut ◆ Nut Width: 41mm ◆ Contents: Locking nut body, tension bar, adjustment wrench, height adjustment spacer/shim, etc. (The items shown in Photo 2 are the contents.) GOTOH, highly regarded both domestically and internationally for its high precision and stable tuning! This is the high-precision locking nut "FGR-1" made by GOTOH. You can use it for a long time with higher tuning accuracy and solid construction. This is a masterpiece that shows GOTOH's attention to detail. Three spacers/metal shims of different thicknesses are included for height adjustment. Fine adjustments can be made to suit the instrument, such as by stacking them. ◆ Both FGR-1 and FGR-2 are 41mm wide locking nuts, and the difference is how the nut is fixed. The FGR-1 is fixed with the included screws from the bottom (back side) of the nut, while the FGR-2 is fixed with the included screws from the top (front side) of the nut. Since the FGR nut width is 41mm, it is mainly suitable for Strat/ST type guitars, etc. GHL-1 and GHL-2 are 43mm wide models and are mainly suitable for Les Paul/LP type guitars. The nut and bridge are where the vibrating strings first transmit their vibrations. If you cut corners here, even a good wood body and neck are meaningless.
