Ernie Ball

Stronger so they last longer.

Gauges 9-11-16-24-32-42.

RPS stands for Reinforced Plain Strings and these 2239 Super Slinky electric guitar strings are a reinforced version of the standard Ernie Ball strings.

A patented winding of bronze wire is tightly wrapped around the lock twist of the ball end. String slippage and breakage are minimized at the ball end where these most often occur. RPS strings last longer and stay in tune better than conventional plain strings. Used on electric and acoustic guitars but not classical guitars.
All Ernie Ball strings are precision manufactured to the highest standards and most exacting specs to assure consistency, optimum performance, and long life.

Ernie Ball is the pioneer of rock and roll guitar strings. Jimmy Page, Eric Clapton, Steve Vai, and Slash are among the long list of Slinky players.


If you want a string that's a little stronger and lasts a little longer, these are the ones to get. Order today.

Comments about Ernie Ball 2239 Super Slinky RPS 9 Electric Guitar Strings:

I was a regular Dean Markley Electric user for years.
When a local store was out of stock, I took RPS Nickel Slinky's in my usual 9-42 gauge to try on my Strat.
Tone was everything you should expect from a 9 gauge in a Strat.
Focused, a tad less brittle than others, warm, dynamic and responsive.
After a few days from the initial use, they settled in and were a great fit for my maple neck USA Strat. Felt really good under my fingers, and responded well and articulate to my playing dynamics.
Last but not least, they last quite long also, longer that the Electrics, but not as long as DR's for instance, which are all more expensive than these.
This is my 6th set, and so far they are consistent as they get.
I decided to switch from Dean Markley to these, at least for now.

My favorite of the EB strings

By Duck2587

Comments about Ernie Ball 2239 Super Slinky RPS 9 Electric Guitar Strings:

If you love tens because of the bigger thicker sound but want some bite, get these! If you play a Floyd rose equipped guitar def get these.
For some reason these are the best 9's I have ever played. Usually 9's or lighter strings produce a bright poppy sound. These have some of that but with warmth to tame it a bit. I can tell a difference between these and the standard 9's. These feel much better as well and feel like better quality. If you are thinking about these or the RPS 10's, get these. Much better. They should make a custom 9 1/2 set like Ghs does.
I change strings every2-3 weeks and I had these on for a month.
For as good as they are they are reasonably priced.

Ernie Ball RPS strings are simply the best, period

By JD-ncN8H

Comments about Ernie Ball 2239 Super Slinky RPS 9 Electric Guitar Strings:

Ernie Ball's RPS strings have a long lasting life and always sound as good as new. I've been playing guitar for about four years now and I've never used anything other than Ernie Ball strings. In my opinion, they are the absolute best.
