TITE-FIT Electric Guitar Strings feature a nickel-plated steel wrap wire on a round core to provide a rich and musical sound. This classic construction provides a strong fundamental with balanced over-tones. Compression Winding allows us to fit more mass on the string, which we feel improves the tone, gives it a smoother feel, and extends its life. These exceptional features have made TITE-FIT the string of choice for top guitar players for over 30 years. Combining the finest US materials available with strict quality control ensures that these strings will meet even the most discerning guitarists high standards. Available in 6, 7 and 8 string sets.
