Dunlop Introduces the Jim Root String Lab Series Guitar Strings

Signature strings from Slipknot's Jim Root designed for exceptional tuning stability and high-end clarity when tuning down.

Jim Root came to the Dunlop String Lab to design a set of strings that can handle blast-beat-driven grooves and extra twisted melodies from downtuned depths. Jim handpicked each gauge and core size to ensure peak performance, from feel and response to tuning stability.

“These strings give me what I need to get my sound, and they’re comfortable to play no matter what I throw at them,” Jim says. “They keep their high-end clarity for a long time, and they’re really consistent from one pack to the next—they never break on me.”

The beauty of the Slötvå reverb (which is derived from the company’s very similar Spin FV-1 chip-based Slö reverb) is how satisfying and simple it makes dramatic shifts between time/space textures.
