Unleash your inner rockstar with Ernie Ball COBALT electric guitar strings!
• Unique Textured Grip: Cobalt offers a textured, matte surface, providing an incredibly playable grip under your fingers.
• Superior Magnetic Response: As a transition metal, cobalt provides a greater magnetic response than nickel, resulting in higher output and a bolder upper midrange.
• Versatile Tone: Clean or distorted, these strings deliver a loud, bright sound with a sparkling top - end and pronounced midrange.
