These strings are as "vintage" as you can get. Pure nickel wrap on a round tin-plated, high carbon steel core. Many players believe that round core strings feel easier to play with less tension and have a clearer tone. By design, round core strings must be handled carefully so that the outer winding does not come lose. On guitars that have an eye in the tuning post, it is important to install the string and tune to pitch before cutting the excess string off. On guitars where the tuning post has a hole down the center which require the string to be cut prior to placing the string down the post hole, it is important that to you first make a 90 degree bend before cutting the string. It best to make that 90 degree bend about two inches longer than the post where you will be installing the string. Once you have made the bend leave about one-half inch before cutting the string then place the bent section inside the tuning post and tune to pitch. Be aware that it takes longer for a round core strings to "settle" in and it requires many more tugs, but once installed and settled in, they are amazing.

    Pure Nickel Electric strings

    Amazing strings, they hold tune well and have a great sound to them. Much better than the GHS Boomers I used to use.

    Awesome strings

    Love these strings. They’re expensive compared to others, but the round core is just so much more playable, bendable, and stable for tuning. They’re on all my electric guitars now.

    Curt Mangan round core pure nickel 10-46

    Posted by Stephen Swortwood on 16th Dec 2020

    Hands down best string I have ever used. This past year I have been restringing all my guitars with the Round Core Pure nickel's 10-46.
    Acoustically improves tone and feel so well you might forget to plug the guitar in. I have these on Gibson, Fender & Epiphone guitars w/ single coils & Humbuckers. The most noticeable difference were on my lower end guitars. My MIK Epiphone sheraton & Fender strat MIM road worn both were greatly improved in tone and feel.

    10-46 pure nickel round core

    Posted by Stephen Swortwood on 27th Sep 2020

    A major improvement on both Fender strat w/ Bareknuckles trilogy suits and tele with Duncan alnico -II singles. A improved stiffness on the non wound strings made bends easier and more focused. While the wounds just seem to be more sensitive with more control with this slinkyness that’s just right. Guitar sounds more expensive unplugged, fantastic clean and great with JCM 800 type hi gain and Germanium fuzztones.

    Pure Nickel Round Core, 10-46

    Posted by Mike Homola on 20th Jul 2020

    Great feel and tone. Full-bodied yet “crisp.” Once stretched, they hold their tune.

    As good as it gets for guitar strings

    Posted by Gary on 31st Dec 2018

    I’ve been using Mangan extensively for a few years now. They are, in my humble opinion, the finest guitar string money can buy. I just recently tried the round core pure nickel and have a new favorite string. These add such warmth and low end that you can’t get from an ordinary string. Whatever pixie dust Curt is using in these I hope he continues. The Pure Nickel is my favorite string and the round core is pretty sweet when it comes to tone. I wouldn’t consider anything else for any of my guitars.

    Round core pure nickel

    Posted by Carl Laesch on 22nd Dec 2018

    These strings seem to sound “better” than the many others I’ve tried, and for some reason also seem to last longer also.

    Pure Nickel Round Core

    Posted by Billy Z on 4th Oct 2018

    There is something about these strings that just feels right.
    I have found all Curt Mangan strings to be superior. They Tune up faster, Stay in tune better, and Last Longer than any other brand I have ever used and I have used most.
    I did have to reintonate for the Fusion matched strings coming from D'addario .

    I tell everyone about Curt Mangan strings, They are the best. I even got my local shop to start carrying them.
