Schaller 3D-4: patented 4-string bass bridge

• The roller bridge saddles reliably minimize string breakage while maintaining intonation and tuning stability.
• 3-dimensional adjustment of string height, intonation and string spacing (with roller bridge saddles).
• String rests with shafts and rollers made of solid and uncoated Pure Sound brass for excellent sound transmission.
• The individual string intonation is set by adjusting the string saddles.
• Heavy and precise construction for extra long sustain.
• The guitar or bass strings lie on low-friction roller saddles which prevent the strings from breaking.
• This means the string spacing can be adjusted flexibly.
• The roll widths are optimized for the standard mood E-A-D-G.
  
  

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.
