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! The "S21" is heavy and solid, with a clear and defined sound, making it a popular steel saddle. It transmits string vibrations directly to the body. The balance of sound for each string is good, and the strength and vibration conductivity are excellent. Originally, it was the saddle for GOTOH's popular bridge part "GTC102," but due to requests to "sell the saddle part only," it is now sold as a standalone product. Since the saddle is the part that the strings directly touch, it can be considered a "consumable" part, and it needs to be replaced to the extent that it doesn't affect the sound. GOTOH's official website provides detailed specifications (dimensions) of the product, so please check it 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 very significant. Using a high-quality saddle can be expected to improve sustain and increase harmonic components. Even those who are hesitant to replace the bridge because it requires modification can try replacing only the saddle relatively easily, so please give it a try. Those who are having trouble with strings falling off often find that replacing the saddle fixes the problem, so we recommend trying it!
