Problem with D string while playing 12string guitars

[Zabis]

I have an interesting bug in my Shuriken Variax I need to fix
Whatever 12string guitar I use theres a problem with D string.
When I play open D string the parallel (high) note is not in octave

but octave plus one halfstep... Therefore only this string is out of tune.
Funny thing is when I start pressing frets on D string the harmonics are

octave as the shoud be... This bug is only while playing open D string.

 

Any ideas how to fix it, Already went through factory reset.

 

Thanks Zabis

1) Is the Alt Tune engaged? If so, it may be 'dual tone effect', where you hear the sound from the strings in standard tuning,

while hearing the Alt Tune sound from the amp. Using headphones or turning up the amp minimizes the effect.

 

2) Do you have the Shuriken bundle loaded? If so, select User III, toggle-1, and tell me which string is sounding.

 

3) The intonation may need to be checked.

Thanks for replying but it´s not that,

Funny thing is that I can fix it with using capo on any fret
so it´s not the end of the world but still it´s a funny lollipop up

I would like  to resolve :)

Capo solving it,... that would point to a string nut slot starting to get worn, which is possible,

as you guitar is a second hand guitar with a built date of 2017.

Yeah it´s second hand but 12string set up is the only one I have problem with...

All other guitar set up is ok.... So I need capo only for 12 string setting.

Intonation or string nut, and being in 12-string mode just brings out more.

 

I use barred harmonics at frets 12, 7 and 5, in12-string mode to check for frequency

artifacts like that when I service Variax guitars here. It brings out things like that.

Thanks, will try that
