M-Steel Power Slinky Electric Strings are a perfect match for those who like chunky rhythms for rock-and-roll or blues. Ernie Ball's M-Steel strings are made of M-Steel, short for Maraging Steel, is a superalloy used in high stress applications for the aerospace and defense industries.

The wound strings are comprised of a patented Super Cobalt alloy wrapped around a Maraging steel hex core wire, producing a richer and fuller tone with powerful low end response. M-Steel plain strings are comprised of a specially tempered steel for maximum fatigue resistance. A patented winding of steel around the ball end of the plain strings reduces slippage, breakage and stays in tune better than conventional plain strings.

  • Ultra high output guitar strings
  • Constructed of Maraging Steel
  • Super Cobalt alloy wrapped around a Maraging Steel hex core wire
  • Provides maximum fatigue resistance
Will replace defective strings.

Sounds Amazing! While they last that is...

By Matt

from Ionia, MI

These strings sound amazing I bought two sets and put them on right after I got them. They locked into tune after playing them for a little bit going only ever so slightly out of tune after having to let it sit for nearly a week. The low end is much warmer than I had expected and the mid-range, where I tend to play a lot, was very pronounced and for lack of better words, in your face. Now here's the problem, I had the strings on my Les Paul for no longer than 2 weeks before the 'g' string or '4' string, whichever you prefer, began to unwind itself inside of the bridge! I thought maybe it was a fluke or possibly the bridge might have played a role in the problem so I put the Les Paul down and picked up my Ibanez which also had the same type of strings but a different gauge. Within a week after the Les Paul incident the EXACT same thing happened. Same issue with the same string. I may be upset about it but for right now I'm going to say I might have gotten a bad batch so I'm going to wait a while before I purchase this set of strings again. Until then, I'm going to be switching back to the good old Cobalts

another Earnie Ball score

By LeRoy Duncan

from Caledonia

Truly love them. The low end response is so much warmer and fuller than I had expected. Well worth the price for those of us who play everything from classic Sabbath to Pantera and Slayer! Would definitely recommend them!

You Get What You Pay For

By Lorena Amaya

from Houston, TX

I'd like to preface this review by stating that I play Blues Metal a la Black Sabbath and will be writing about the product accordingly. I walked in to my local Guitar Center to purchase a few items and noticed these as I was grabbing some picks. I read the specs on the back to check the frequency response of the strings and was a little skeptical at first. Increased decibel range and a better response in the hi-lo and mid frequencies?! I had just replaced my strings with some D'Addario XL Jazz Lights (.12-.52) and I was pleased with their overall sound, but my guitar still needed to be cleaned, so I said what the hell and bought them even with their "higher" price tag. Man, I can't begin to explain how awesome these strings are. They're LOUD, but in all the right ways. My brother has a custom kit, which can't help but drown out my playing. The frequency response on these is perfect as it helps the mid-high end of the guitar shine through and the wide boost at the low end acts as a "dither", boosting the gain on the guitar. The strings have some "gain" or bite right out of the packaging. I actually had to go back and reset the parameters on my amplifier to counteract the additional gain and bass boost. The "stickiness" of the string took some getting used to, but once I got a grip on it they were perfect for bends as it helped enhance my guitar's sustain. Honestly, I will now probably stay away from coated strings (ex/ Elixir) due to my experience with these. My last note to add would be the fact that these strings are very unforgiving and I would not recommend them for a novice/beginner player. You have to know how to handle your guitar to provide the best possible intonation in your signal. When I first tried them out, I was playing a bit sloppy due to the difference in feel and what some would consider "stiffness" of the strings, but once I broke them in my ears were sold. I have yet to try these in the recording studio, but my next session is this following Tuesday and I can honestly say that I am chomping at the bit to hear the difference in tone from previous recordings. As stated previously, I play heavier riffs with a lot of jazz style picking and I am beyond amazed at what the ear test is telling me. Do yourself a favor, buy these and try them out. I think you'll be pleasantly surprised.

Absolutely Awesome Strings

By Jack Gibson

from Las Vegas, NV

I bought 3 packs at my local GC this week, and am 100 % sold on these. Not only did I notice an increase in output, but I also noticed a significant improvement in tuning stability. I've played four shows in the last week, and kept the same set on my main PRS guitar. They still sound brand new, and I haven't had any reason to change them. Fantastic innovation EB....

By Jeffrey Freund

from Plymouth WI

I by no means am a great guitar player. I bought these strings just to try out. They made any thing I played sound out of tune and just plain awful. I thought It was a tuning issue but my guitar was tuned dead on. Standard or drop D, it didn't matter.

Too stiff

By Arthur Hagen

from Granby, CT

These are much like the Cobalt strings, but stiffer. When I tried them, the bass strings got bent from the frets, nut and bridge after just minutes of playing, because the strings are so stiff. For me, they were also much harder to do pinch harmonics on than the Cobalts.
