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.

    Best strings I’ve played

    I only play Curt Mangan strings — for me, the quality, tone, playability, and longevity are second to none. I am very selective (picky) about my strings. What I really appreciate is the ability to create a set with my specific gauge preferences, which are not available in off-the-shelf sets. I am completely satisfied with all aspects of Curt Mangan strings and can recommend them without reservation. Thanks Curt!!

    Fusion Matched, Round Core, Pure Nickel strings

    Posted by Jim on 8th Jun 2020

    I've just strung up two of my main guitars with these strings - so far, I'm really liking the feel and the sound. The round core and nickel are getting harder and harder to find these days. A big thumbs up!

    Pure Nickel Round Core!!!

    Posted by Scott McKusick on 2nd Dec 2019

    I have been playing guitar for over 20 years and had eventually sort of "stuck" with my usual brand of strings because they were the ones that worked for me -- not that they excited me to play exactly, they just worked. For some odd reason, I decided to try something different and ordered my first-ever custom set of round core pure nickels -- the round core being new to me (I've always played hex cores). After receiving my strings in a very professional-looking sealed package (looks like I just bought it off the rack at the store), I was immediately blown away by three things: 1. The round cores feel great under my fingers, are easy to bend and sound fantastic (a nod to the pure nickel windings), 2. The customer service was amazing -- although I live at the top of the world (a mere iceberg to the east from Barrow, Alaska) my strings arrived within a week (faster than even Amazon Prime), and 3. I got to pick my own gauges (including half sizes)! My conclusion: I will never buy mass-produced strings again when I can get this level of sound, feel, and customer service for about the same price as other "premium" strings. Thanks, Curt, for getting me excited about playing again – you rock!
