The Ernie Ball 2834 Super Slinky is a four-string bass set with gauges of .045, .065, .080, and .100. The strings use nickel-plated steel wrap wire wound over a tin-plated hex-shaped steel core for a bright, punchy, well-balanced tone. Made in the Coachella Valley of California, the set ships in hermetically sealed foil packaging to protect against humidity.
