I suspect only two people have knowledge of the "intricate details" of the PPT mats, and one isn't with us anymore. I don't think that knowledge is necessary though, to understand that they do work. I have multiple mats of the second and third generation. I believe they get incrementally stronger with each generation. I have met no one who actually owns these mats who doesn't find a significant increase in presence and breath in their system. I personally don't care how they are manufactured, but since I have spoken with Tim and Krissy many times through the years, I do believe these were home grown products. Few luthiers make every single part of the the guitar, although some do. Noble is one luthier who does. Most will purchase machine heads and other minor items and build the majority of the guitar themselves and make something unique. The real question you should be asking, is where can I get some. When these products were sold by PPT they had a money back guarantee. I doubt there are many used items on the market. Good luck.
