POD 500x Delay (I think) causing weird noise

[robertmcollins3]

I'm getting a strange noise when using any delay on the POD.  I managed to narrow it down to the delay that was causing the issue, as it doesn't do it when the delay is off.  I've tried various delays, analog, tape, dynamic, etc and they all seem to do it.  

 

I thought it might just be my cheap computer speakers, but I also notice it when plugged into my amp.  I tried going straight to the amp (no POD) and it's not there.  I turn the delay off on my patch (any patch really) and it goes away as well.

 

Here is a quick example of the problem:

It very noticeable when I change to the second note, and especially after I turn on some overdrive.  Any ideas?  

 

I've never noticed it live, so maybe it's some frequency interacting with the POD (but only when using delay!) ?  Driving me nuts.

 

Here is the patch where I first noticed it, but it happens on others as well:  http://line6.com/customtone/tone/856429/

Okay, I tried the path myself and the sound I get is normal. Listening to your demo, it sounds like digital clipping. What you can try is to move the delay after the mixer block and/or lower you guitar volume and see if this helps.

Just tried this again live, and it sounded great, didn't notice it at all.  So who knows?  Maybe something in the house that is causing it.  I do have the amp volume at 100% in the patch.  I'll try and see if that fixes it at home, but for now I guess it's just one of those things where live is different than home.
