DAddario NYXL Heavy Electric Guitar Strings - 12-54

The D’Addario NYXL Heavy 12–54 set is a premium uncoated electric guitar string pack built for players who demand higher tension, stronger output, and rock-solid tuning stability. Featuring a high-carbon NY Steel core and nickel-plated wrap wire, these strings offer superior strength, enhanced midrange presence, and a bold, punchy tone that cuts through any mix. The heavy 12–54 gauge provides increased resistance and control, making it ideal for hard picking, drop tunings, and powerful rhythm work, while still allowing flexibility thanks to its plain steel G string.
