Signature (9, 11, 16, 28, 38, 50) Signature Set. Nickel-PLated on Hexagonal Core, treated with String Life. “I’ve been playin’ the strings of strength since 1995. They’re 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.”
