The base is a Montreux ABR-1 style Bridge wired Nickel, the type with wires from the 60s onwards. Montreux also sells a relic version, but this is a new, non-relic item that has been relic-processed. The area where the hand touches during bridge muting has been given a shine. Rust has been applied, but it is not real rust, so there is no risk of rapid corrosion and the octave adjustment screws becoming unmovable with use. ■ Saddle wired fastening specification ■ Nickel ■ Stud screw 73mm ■ Stud spacing screw 74mm ■ String spacing: 10.5mm ■ Post hole diameter: 4mm Inch size It's finished with a subtle relic look that will easily match the atmosphere of vintage Les Pauls, as well as used guitars.
