Advantages of Pure Sound brass

• Due to its softness, brass is an ideal saddle material and offers sufficient resistance to the strings. 
• Uncoated brass saddles (plain or notched) can be easily customized by the guitar maker with a saddle file for smooth transitions.
• Form-fit support of the components in conjunction with improved string contact thus supports playability, intonation and sustain.
