Thank you very much for your request. Since you purchased ★GOTOH / GB2-Ni-L4◆ on a separate page, we will ship this ★GOTOH / 203B-4-N◆ together with Letter Pack Plus. Specifications ◆Model Name: 203B-4 ◆Finish (Color): N / Nickel ◆String Pitch: 19mm ◆Brass Saddle ◆Metric Size This is a bridge for 4-string basses from GOTOH. GOTOH, a Japanese brand known worldwide for its high-quality, premium parts! This "203B" series bridge is a model that improves on the problems seen in Fender bass bridges. It is a standard model with a 7-point mounting design, offering the most affordable and sufficient functionality. For basses where techniques like downpicking and slap (chopper) playing are common, which put excessive impact on the strings, there are issues such as the saddle slipping sideways, damaging the bridge itself, or unstable tuning. This bridge is well-designed to address those points, offering easy and significant improvements. The quality of the bridge is also what you would expect from GOTOH, with very positive feedback on the dramatic effects, such as extended sustain, increased harmonic content, and clearer sound definition. The pegs, nut, and bridge are the first points where the vibrating strings transmit their vibrations. If you cut corners here, it negates the value of a good wood body and neck. Please refer to the GOTOH official website for details on screw diameters, etc.
