BAJAAO India introduces the D'Addario EJ46.The Composites are the newest innovation from D`Addario. They are different from the Pro Arte strings in two ways. First, the basses use a different type of nylon, a composite polymer that markedly improves the longevity and projection of their already excellent basses. Secondly, they include two 3rd strings in the package, one traditional Pro Arte and the other made of the same core material that the bass strings use. This new 3rd string is quite a bit brighter than the Pro Arte 3rd, and bridges the tone color gap between the 4th and 2nd strings much more evenly. It is radically different enough that D`Addario has also included a Pro Arte 3rd for those who prefer a more traditional 3rd.
