Specifications ◆ Model Name: FGR-2 ◆ Finish (Color): GG / Gold ◆ Type: Locking Nut ◆ Nut Width: 41mm ◆ Contents: Locking nut body, tension bar, adjustment wrench, height adjustment spacer/shim, etc. GOTOH, highly regarded both domestically and internationally for its high precision and stable tuning! This is the high-precision locking nut "FGR-2" made by GOTOH. You can use it for a long time with higher tuning accuracy and solid construction. This is a gem that shows GOTOH's attention to detail. Three spacers/metal shims of different thicknesses for height adjustment are included. Fine adjustments are possible 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. FGR-1 uses screws (included) to fix the nut from the bottom (back side), while FGR-2 uses screws (included) to fix the nut from the top (front side). 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.
