Slash

Slash mainly uses Ernie Ball Power Slinky RPS 11-48 strings. "Ernie Balls have been consistently great sounding," he says in this interview at (0:15). "They don't oxidize too fast, and they don't break. They're tremendously reliable.," he said.

Slash and Adam Day talk about the Ernie Ball Paradigm strings in this video and how they are able to combat Slashs history of breaking strings.

Adam Day can be seen stringing up Slashs guitar with the Paradigms throughout the video and Slash can be seen using the strings at 2:05.

The official Ernie Ball website states:

Ernie Ball introduces a limited edition set of custom wound Slash signature Slinky strings. Slash’s new signature string sets are the culmination of over three decades of Slash and Ernie Ball’s ongoing pursuit to create strings that provide more durability and tuning stability without sacrificing tone or feel. These new sets consist of his preferred 11-48 gauge Slinkys wound with Paradigm core wire and plasma-enhanced nickel-plated steel wrap wire, while the Paradigm plain strings are constructed with a heavier brass wire reinforcement at each of the ball ends for better tuning stability and strength. These limited edition string sets are highly collectible and conveniently packaged in a three-pack tin box for easy storage.

Slash praises the Ernie Ball Cobalt Power Slinky Strings (11-48) for their superior sound and feel, as highlighted on Guitar Center's product page.
