Amp feedback mystery eliminated
You folks might have already run across this issue but it was new to me and drove me nuts until I found the cause
I suddenly started getting a goofy feedback in my Ultrasound amp
It would come and go at random , increasing and decreasing in volume
I checked out all my cables and mic, looking for the usual suspects
but found nothing wrong
Unplugged everything and sat down and waited..... sure enough, the feedback returned
I thought, maybe I have an intermittent short or component in my amp
Finally, I walked away from the switched on amp
to do something else, and as I was returning the feedback returned and went wild as I approached the chair beside the amp
Yup,
This new phone I just bought was in my pocket and was transmitting something, somehow,
to the amp every time I turned a certain way while sitting in my picking chair, and also when I walked up to the already turned on amp
Anyhow, phone now sits on a table across the room from where I pick
Amp is happy, old man picker is happy
Just thought I'd pass this on, might help somebody else
