Göldo Deluxe 4D 5-strings bass guitar bridge, chrome. The base plate of legendary 4D bridge is machined from solid brass. The strings lie on fat steel wheels, which can be moved sideways to adjust the desired string spacing. After all adjustment work has been done, the saddles are fixed with the help of side grub screws. This welds the individual parts together to form a firm unit and guarantees perfect vibration transmission and thus the optimum in terms of sound and sustain. Matching hexagonal wrenches are included.
