    Hey folks. I’ve been setting up my own guitars for almost 20 years, all different bridges, scale lengths, etc., but have encountered an issue that I’ve never experienced before.

    I just picked up an Epiphone Elitist Casino - cool guitar. I put some DR pure nickel 11-50s on it, because I wanted something more mellow and a slightly heavier gauge than I usually use. Here’s the issue I’m having:

    The D string is slightly flat from about the 3rd fret to the 10th, but comes back in line around the 12th fret. I don’t have the same problem on any of the other strings. It’s only about 2.5 cents flat at the worst point, but I can hear it. My first thought was the nut, but that should have the greatest impact closest to the nut. This is the worst around the 7th-8th fret.

    Anyone ever had this kind of issue? Any idea what could be causing it?

    You are flat in the center section. To me that implies a high bridge and a high nut. Are you tuning to open or fretted strings?

    I’m tuning to both a Boss TU-2 and an iPhone tuner app that shows Hz.

    I’ll need to dig into that page when I don’t have to divide my attention. Thanks!

    I’m going to go get my standard string set to compare, change them out tonight, and see where I’m at.

    A string can be bad from the get go. Since there is only one string giving you this problem, the string is suspect, imho. Or....is the radius at the bridge proper??

    I think I must play differently with flatwounds, like maybe my fretting hand is more delicate? When I play roundwounds I tend to go sharp for some reason. It has to be me, but it is pretty consistent. So I don’t keep round wounds on too many guitars unless they are at least 11s. I have flat 9s on my little strat and have no trouble, flat 12s on my G&L and no trouble. But I have A new set of Elixer 10s on my 339 and it’s wonky when I play it. Not enough to be drastic but enough that I can hear it on my Jazz shell chords.

    Both. You'll be in tune only on the octaves, really. And it might be a dead string.

    How is the fret wear along the D string?

    Excessive fret wear takes notes sharp, ime.

    I was thinking the same, unless the 12th is unusually worn? :):rolleyes:

    If it was mine, I'd replace the string before getting surgical on the guitar.

    I used DR Pure Nickel for about a year. Had to walk away - too many bad strings. Went back to Fender strings.

    Just changed the strings to Ernie Ball Beefy Slinkys and everything is fine. Musta been a bad string. Bummer, I was happy to find pure nickel 11s locally. Guess I’ll need to order online if I want some that aren’t DRs.

    Thanks all!

    So what would make a particular string do that? Thin spot? Overdrawn? I can see that, I guess.

    Think so, yes. Possibly more conditions relating to the raw material before drawing...?

    Definitely this.

    Think of the intonation difference between a tall narrow fret that has had a fret level or two and a nice crowning, versus a Gibson style fret that has a distorted shape due to extensive wear. Also, take into consideration Gibson frets are funny to begin with due to their wide/square shape. Not good for intonation.

    My opinion.

    A properly crowned fret will present the same witness point regardless of its width. If the frets are not properly crowned; then yes...a wide fret can present a wider witness point.

    Glad that worked out easily. What a pain it is to buy a set of strings, come home and put them on, and have one turn out to be defective. And good luck trying to buy a single, nobody sells them that way. Got to buy a whole set again. I don't know why I started getting DR instead of Fender, must have bumped my head, :)

    I use Fender nickel wrap now, I forget the exact designation. Fender 150, maybe?
