I think this has been mentioned before but I cannot find it so I will throw it out anew.
Although I do not get feedback using closed grip tips, I get an intermittent very low level “squeal” which sounds just like feedback squeal but much quieter. It happens in any environment and occurs every few minutes but only lasts for maybe one second. It only occurs in my left ear which is the one with the slightly better hearing.
I guess this is related to the feedback management process but why always in the left ear and so frequently.
Any pointers gratefully accepted.
