DR MT-10 Tite-Fit Medium Electric Guitar Strings are nickel plated and based upon a round core. The construction techniques for Tite-Fit strings are very old. However, the core wire and wrap wire in DRs are the latest, most advanced and expensive metals available. For flexibility, for tone, for long life, Tite-Fits are a wonderful all-around string.
String guages: 10, 13, 17, 26, 34, 44
