New Callaham CNC Machined Steel Billet ABR-1 tune-a-matic Bridges for Gibson Type Guitars

 We started this project in February of 2009 to solve the problem of a completely inferior bridge material used by Gibson since 1954 and copied by every aftermarket bridge maker since. All ABR-1 bridges and their aftermarket copies have been made of ZINC (pot metal). Zinc is a tremendous dampener and never should come in contact so directly with the strings as it does on an ABR-1 bridge. But casting a bridge body in zinc is very cheap. I try not to use the inflated adjectives used by so many in this business, but our machined billet steel bridge body will make any guitar using an ABR-1 or a Nashville Tun-a-matic bridge into a true stringed instrument. The widening of frequency response, the focus and note separation of chords, and true singing effortless sustain will be obtained. The first run is at plating now and should be back for inspection in a few weeks. We will have stainless steel stud/thumbscrew kits for changing a traditional ABR-1 bridge and a special stud kit for converting a Nashville bridge to our ABR-1 bridge. There will be a completely new page added for this bridge when everything is ready. Projected retail price will be between $115.00 to $120.00. If you have advanced questions now, please e-mail us.
