DR's Tite-Fit strings are round-wound, nickel-plated electric guitar strings. They're designed to be just a great all-around string, no matter your style of playing. The Tite-Fit's round-core construction is based on time-proven string-making techniques - although DR gives the Tite-Fit strings their most advanced core wire and wrap wire metals, to unite the best of the old with the best of the new. Perfect for everything from rock to blues to metal to jazz, DR Tite-Fit strings are versatile - and DR's most popular.
