I was sure i posted somewhere around about that problem but i can’t find the thread anymore…
When plugging my guitar to the OT the C note is almost cancelled, huge drop in volume like a phase issue.
If i check Delay Compensate in the Control Input menu, it’s ok but… i now have an issue with the A note (and frequencies around) that are now dropping…
Anyone had this issue?
PS:@sezare56 i’m sure we discussed it but where?
Yes I remember. On AF maybe?
What is your monitoring way?
Same problem with DIR only (new project)
What’s your guitar signal?
Guitar is the only thing plugged? (no fx loop?)
I did not find on AF either…
I checked all the signal path, unplugged the FX loop before posting and the guitar is straight in the OT.
But indeed it doesn’t happen in a new project. I was so obsessed within the project i did not even think about trying in a new project.
Still the problem persists in my first project and i find it quite strange.
Did you mute all tracks exept monitoring (DIR, or THRU, FLEX, PICKUP)?
Something that can happened: when the problem occured some months ago, the C note disappeared and i checked Delay compensate to sort it out.
Since that time i took habit to check it in every new project (can’t remember in which project it did occur first time) and it seems it is actually boosting my C note.
Now i just came back to the problematic project and it sounds quite even when i uncheck it 
For me it means you’re monitoring twice.
Yes i did.
I can’t remember the calculation you made in the first thread about it.
Actually if i am more precise it is more the C# that is boosted and the A lacks low end.
I thought it was just introducing an offset?
Yes, but between 2 signals.
Maybe you’re using a Thru and DIR?
I’d check mutes twice.
Nope i never open the DIR but the gain is +63.
2 Thrus?
A Thru + Pickup or Flex?
I don’t understand the question.
I have only one Thru for the guitar, i don’t play it on a flex if that’s what you mean.
2 monitoring sources with offset would explain the phase “cancelation”.
Ok i get the asking about FX loop then 
If this whole cancel culture thing wasn’t absurd enough, now the OT has canceled middle c!?!??? (I’ll see myself out)
