Highs in signal have disappeared

[TheBigUmberto]

Hello, I feel like I'm having a component malfunction on my Line 6 Pod Go. I have had the Pod Go for a few years now and it's been great. The other day, I turned it on and was using an 80s'ish metal preset that I created a while ago and it sounded like someone put a blanket over the highs and the initial attack of the note is completely muffled now. I'm aware of Pod Go impedance issues and using global or preset EQ's to make things sound better but this happened out of nowhere without any changes being made to the preset. Working fine one day, come back the next day, turn it on, and it sounds completely different without me having made any updates. I tested the guitar and cable using the Pod Go as an interface to use a Neural plugin and everything sounded fine, so that rules out the cable or the guitar being the problem. Has anyone encountered this before? If this is a problem with the Pod Go, how would I even go about diagnosing it and it getting it fixed?

Are you using the stock cabs or an IR? Reason I'm asking is because I am using IR's. For some reason (and not always) when I'm copying and pasting a preset into a new preset location, the high end on the IR cab will be like you set it to zero. No treble at all. Like someone put 10 blankets over the speaker.

 

But then the other day (and without making a copy) I went to one of my presets and there was no treble. So I just re-adjusted to high level on the IR cab back to where I had it, saved it and all was fine. Don't know if this has been of any help to you, but you're not alone. I have no idea in either circumstance why this happens but it's been an easy fix.
