At Ernie Ball, we’re making a change that’s actually a return to form.
We’re introducing a universal envelope system for our plain strings across nine of our best-selling acoustic and electric alloys. That means whether you’re buying a full set or a single replacement plain string, the plain string packaging will now be the same as Slinky, Slinky Classic, and more!
Did You Know?
The following string sets all include the same plain strings—meaning any of the matching-gauge singles can be used interchangeably between them: Slinky Nickel Wound
– Slinky Classic Rock N Roll
– Slinky Flatwound
– Slinky Cobalt
–Slinky Stainless Steel
–Earthwood Bell Bronze
–Earthwood 80/20 Bronze
–Earthwood Phosphor Bronze
–Aluminum Bronze
So, why the change?
–Transparency — You’ll know exactly what you’re getting. Each envelope will clearly indicate the string gauge.
–Consistency — Whether you buy a single plain string or a full set, the packaging is now universal—no more guesswork.
–History — This isn’t new for us. We packaged plain strings this way until around 1980. We’re bringing it back.

So, whether you’re choosing strings for your own custom set or just need a replacement, finding the right plain string has never been easier.
