The Helix SS Bass Guitar Strings are the latest addition to the Dean Markley family of legendary quality and innovation. Stainless steel alloy has an inherent bright and cutting timbre to it. It gives the strings an unforgettable stainless tone. Something you need to play to really understand. Helix SS bass guitar strings feature the Hyper Elliptical Windings (compressed from side to side), which gives Helix more mass and tone, as well as extended life. This Hyper Elliptical winding is what gives Helix a more relaxed feel, with a lot less squeak and sliding noises than normal strings. Gauges .045, .065, .085 and .105
