Callaham ABR-1 Bridge
The bridge body is made from cold rolled medium carbon steel. Rigid quality controls are checked throughout the bodies production. The body is nickel plated to mil spec standards to maintain all critical dimensions. The intonation screws, mounting studs, and thumbwheels are stainless steel. It is the quality control in production and plating that allows the intonation screws to be a press fit into the body. The saddles are machined from the same brass bar stock Callaham make their Tele saddles before being nickel plated.
What you will hear with the change to steel is a low end that is tight but full. The fuzz should be gone, if it is not, you need to look at your pickups. The tone will be balanced correctly when moving from wound to plain strings. The plain strings will be full without the harsh high end spike. Sustain is improved substantially making vibrato childs play. Many of you have also been victim to the collapsing of the stock bridge from string pressure. You will not collapse our steel bridge. The rigidity of the steel will allow the use of heavy string gauges and again maintaining the strings energy far better than zinc, aluminum, or brass.
Since the mid 80’s Gibson started equipping the majority of their models with the Nashville bridge. This bridge which was marketed as an improvement is in fact a step backwards. The honeycombed zinc casting is weak and the extra width of the bridge causes problems with obtaining the correct back angle to the tailpiece. Our Nashville conversion kit allows the seamless replacement of a Nashville bridge to our ABR-1 bridge. With this change you not only gain the undeniable tonal improvements but the vintage look without any modification to the instrument.
On the subject of looks, today’s ABR-1 bridges have none of the handworking and tapering of the ends of the bridges from the mid/late 50’s. Callaham specifically machined the ends to a taper and through the course of hand polishing recreate the look of the late 50’s bridge bodies. The stainless steel thumbwheels are thinner like the 50’s model compared to today’s production.
