My 50's LG2 has an adjustable porcelain bridge but glued on mahogany or rosewood. It is pretty special with everything I was needed in a acoustic. Once I made room in my budget I went looking for an adjustable bridge SJ and discovered the CW. Some of these adjustable bridge guitars are amazingly responsive instruments that jump out at you. But only a few of them. I have found that the rosewood saddles dampen the response and feel soft. I tried a good number of them over my long search and was disappointed. Luckily the saddles are interchangeable and available - unfortunately you don't have saddles on hand when you are considering a very large purchase. I got very lucky and was fortunate to be willing to take on the project.
I have a '62 Country Western that had the plastic bridge with porcelain saddle. It sounded tremendous. Jangly and boomy all at the same time. It had a crack that was worsening so I had to replace it. I tried to find a plastic replacement but none was to be found despite my and my luthier's best attempts. I replaced it with an ebony glued on bridge but kept the porcelain adjustable saddle - to retain the response I had grown accustomed to and also to keep the original aesthetic. We had to make a bunch of adjustments before it and I were happy together again. It sounds even fuller now and the response is amazing. I am very pleased with the result, but just to be clear - if I could have found another plastic bridge I would have put that in.
