Unwanted harmonics at 10-12th frets on high E... help!

    Just in case it needs clarification, this isn't a normal natural harmonic (I posted about this on reddit and some guy thought I just wasn't fretting the note completely). It's only really noticeable on high distortion tones but there's this really high pitched harmonic and the note doesn't sustain very well.

    I've tried raising the action quite a bit but it didn't seem to help. I previously was using a higher gauge set of strings for drop C and switched to D'Addario EXL125-3Ds for E standard, so I added some relief to the neck as well but that didn't seem to help either.

    Some other troubleshooting notes:
    • It's not happening on any of the other strings
    • It's happening even when muting the other strings

    Is that string perfectly intonated?

    What guitar? Maybe try lowering the pickup a bit on the treble side.

    ESP Horizon NT-ii. I've tried lowering the pickups as well, and I'm pretty sure intonation is fine.

    Are the frets level in that area?

    The frets seem to be fine from what I can tell. I can try taking a pic when I get home if you want.

    You may be hitting the resonant frequency.
    Is it only happening on one string, or several?
    Have you tested one string at a time to isolate?

    I got the same problem on my G-string when I adjusted the truss rod and lowered the action. Every note on 15-17th fret sounds like a pinch harmonic.

    Yeah that's how I would describe the sound as well. Only thing is this is happening before and after adjusting truss rod/action. I'm probably just going to have to take the guitar to a shop this weekend and have someone else look at it if I can't come up with anything else to try.

    This is usually a sign of a high fret, or too much relief, or backbow if happening more in the middle of the neck. which is making it fret out. Raise your action enough it should stop. A less likely thing could be your bridge saddle, but I'm betting its a high fret.

    I was thinking maybe it was buzzing on one of the higher frets but after raising the action there's an obvious clearance between the string and the next frets when fretting at the 10th-12th so I'm not sure why it would still be happening.

    String could be oscillating funky and hitting a fret up the board yes. It's generally one if the few things mentioned already. But if your neck is straight. or not having excessive relief it's usually a high fret (or low fret for that matter, making the next frets "high")​

    I have had something very similar happen and it was actually a faulty string believe it or not, started happening pretty much straight after a string change too. Took it to a tech that re setup my whole guitar and adjusted the pickup height (which I did NOT want them to do) but it kept happening as they put the same string back on. Swapped out the high e and it never happened again.

    Unfortunately the issue is still present even after changing the string. :(

    Do you have multiple guitars? Does this happen with them too? Maybe not just in this same area but in other areas as well or instead?

    Yeah it's not happening on my other guitars. I took it to a well reviewed local guitar shop for a full setup and pointed the issue out to them; they didn't think they could fix it. At this point I'm just gonna live with it for now since to me it's a minor issue and not super noticeable unless you're really paying attention and holding the note at those few frets.

    Did the tech use a fret-rocker to see if there was a high fret?

    Does it happen with other pickups than the bridge?

    To me it sounds also like a high fret
