The Dimebag Darrell signature Hi-Voltage electric guitar strings stay in tune and remain bright and fresh for a long time. DR Hi-Voltages are made for string bends, whammy-bar dives, harmonic screams, and chunky riffs. Ive been playin the strings of strength since 1995. I like the way DR Strings feel and react, you can really get a grip on them. Theyre great for everything, from big ol string bends, to huge whammy bar dives, perfect for blood curdling harmonic screams and just straight out heavy chunky riffin. They also stay in perfect tune and remain fresh and bright for an amazingly long time said Dimebag. Gauges 09-11-16-24-32-42.Gauges 09-11-16-24-32-42 Stay in tune longer Remain bright and fresh
