Light & Heavy (9, 11, 16, 26, 36, 46) Nickel Plated Electric Guitar Strings wound on Hexagonal Cores. Hi-Beam electric guitar strings are very much like the standard Tite-Fit electrics in feel and flexibility, but are much brighter with similar tone characteristics. For the rockers and head-bangers looking more for brightness and edge than in the warmth and fatness of the standard Tite-Fits.
