Specifications ◆ Model Name: S21 ◆ Finish (Color): C / Chrome ◆ Type: Saddle Set ◆ String Pitch: 10.5mm ◆ Material: Steel ◆ Metric Size Made in Japan! This is the steel saddle "S21" made by GOTOH. GOTOH, known as a high-quality, premium parts manufacturer! This "S21" is heavy and solid, with a clear and defined sound, making it a consistently popular steel saddle. It transmits string vibrations directly to the body. The balance of sound for each individual string is excellent. It boasts not only strength but also superb vibration conductivity. Originally, it was the saddle for GOTOH's popular bridge part "GTC102," but due to requests for "selling the saddle part alone," it is now sold as a standalone product. Since the saddle is the part that the strings directly contact, it can be considered a "consumable" of sorts, and it needs to be replaced to maintain sound quality. GOTOH's official website provides detailed specifications (dimensions) of the product, so please check there. The saddle is the part that first receives the string's vibrations. Although it's a small part, the change in sound due to replacing this part is significant. Using a high-quality saddle can be expected to improve sustain and increase harmonic content. For those hesitant to replace the bridge because of the need for modifications, replacing only the saddle is relatively easy, so please give it a try. Those having trouble with strings falling off often find that saddle replacement solves the problem, so we encourage you to try it!
