Flatmount bridge for electric guitar with adjustable height, intonation and string spacing (roller bridge saddles). 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. You can use the screw on the treble side to fix the string saddles in place so that they don't knock together and rattle when aggressive playing techniques are used. The strings lie on low-friction roller saddles which prevent the strings from breaking. This means the string spacing can be adjusted flexibly.
