EQ effect hummm

[Indianrock2020]

Anyone noticed this?     I usually test patches at decent volume through my Alto powered speaker, but today I tried plugging earphones into the POD (500x ) and noticed when I switched on either a parametric, Studio or Mid-focus eq I was getting a slight hum.  Tried moving them around in the patch and it didn't seem to matter.  It isn't really noticeable through my speaker.  I always have a noise gate first in  my patches but moving that before or after the offending EQ effect made no difference.

 

The patch originally had just a jazz rivet amp, but other amps had the same result from the EQs no matter how low the gain.

Hey there Indianrock2020,

 

Strange, this is the first case I personally have heard of with the EQ's adding a slight hum. Since you're using noise gates, and moving stuff around it sounds like you're set up nicely. 

 

I would start off by performing a factory reset and re-test. 

 

Here is a tutorial on how to reset your POD HD: http://line6.com/support/page

 

Let us know your results.

 

Thank you!

Have you tried to alter the HUM setting in the amp?

I had this problem and the editing worked.

I'll try it but odd that I don't hear the hum with the EQs off, without ever touching the HUM setting.  I may also try unplugging the 1/4 inch cable from pod to speaker while monitoring with earphones, just in case there is some kind of ground loop going on, but again, doesn't do it with the EQs off.
