Does anyone make a Gibson style 12 String Roller bridge or string saver bridge?

A friend of mine wants me to work on his double neck SG and want the bridges changed as they keep breaking strings.

Any help would be appreciated.

Before you spend a bunch of money on new bridges do the following:

Look closely at the existing saddles, looking for sharp edges at the areas that contact the strings. You may need to use a magnifier if your eyes are like mine. Many new bridges have a knife edge at the string break-over point. You can use needle files to smooth over the sharp edges and this will probably take care of the problem.

I just finished building a double neck and have worked on a friends EDS,, both with ToM bridges. The 12 string bridge is wider than the six and as far as I know, there is no roller version available. However I would ask why he is breaking strings in the first place, what gauges he is using and which strings break. The most common set is the D'Addario EXL150 which is 10 to 46 with a 0.008 G octave, the tension are almost exactly the same as a standard set of 10's. What do you think the roller bridge will do to keep them from breaking? I think of roller bridges being good for guitars with tremolos where you want minimum friction, once a string is brought to tension it shouldn't break.

Yep very common to have a burr in a saddle that is the culprit of a broken string.

Our process is to back file the saddles with an appropriately gauged nut file and then we go in with a Dremel with a Stew-Mac fret polishing wheel chucked up. The wheel has been run against an old, crappy file to turn the abrasive wheel into a "V" shaped edge. The point of the V is used to polish the bearing surfaces of the saddle slot, each saddle slot and eliminate any burrs and sharp edges. It just takes a few minutes to do and no more string breakage at least over the saddles anymore.
