Horrid squealing feedback with POD Go through studio monitors

[ericjknabe]

With my POD Go, I get this high pitched squealing feedback through my studio monitors or a PA if I stand to close to the speakers. The sound is like microphonic feedback, but I know it isn’t that because I made sure all my pickups were wax-potted. It happens no matter what guitar I’m using. I’ve tried my guitars through regular amps and it’s fine. 
When my guitar is unplugged, if I point the cable at the speaker it squeals just the same. 
 

I have suspected it may be due to the pickup magnet inductively coupling with the tweeter magnet (Cliff from Fractal Audio talks about this phenomenon on the AxeFx wiki) but at the same time, I’ve tried using a regular cab instead of a frfr style monitor and it still happened. The only other thing I could maybe think of is my power cable is frayed a little bit. 
 

any ideas on how to fix this issue?

Patient: My ears hurt when I do this.

Doctor: Well,  then don’t do that.

 

Please excuse my attempt at humour….

 

It sounds like some sort of feedback loop in your household circuitry. Try connecting the POD Go and your monitors to different electrical outlets, ideally different circuits.

Single coils I'm guessing?  I think it's normal behavior, but hard to tell not knowing the extent.  But basically, the signal pickups generate is quite faint, so it requires amplification and that's enough to pickup ambient electromagnetic noise from speakers or other electronic devices. 

 

Wax potting can help, but it's not a magical solution.  Shielded speakers can help, but again, not perfect.  Pickups vary a bit too.  Some humbuckers can be more noisy than others.  You could try shielding your guitar https://humbuckersoup.com/shielded-guitar-cavity-really-necessary/ but again, can help, but not a miracle cure.  No perfect solution exist imho

 

Also, try different Pod Go amps, some work fine for single coils but others behave similarly as you describe.  So just playing around in Amp/effects could help.

 

If single coils (Fender style) and you set your 5 way switch at position 2 or 4, does the issue go away?

try factory presets first.

Think the odds of being something wrong with the Go is very low, as described in OP it's just normal guitar behavior, especially with single coils & distortion.

 

Easy way to test is step away from electronics and testing, if the same thing happens, then yes, it's Go, but if it is significantly reduced or eliminated, it's normal.
