Korpa 
Patented 4-string bass bridge, analog to 3D-6. 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).
The individual string intonation is set by adjusting the string saddles.
Heavy and precise construction for extra long sustain.
Complete with 3mm or 4mm spacer.
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.
All bridges are supplied with a 3mm baseplate and screws as standard; alternatively, they can also be ordered with a 4mm baseplate.
Optionally, two rollers can be mounted per string ferrule for double string guiding.
