Thanks @stephensawall for chiming in it’s great you have the same gear too.
Joe’s video helped me a lot to understand how to fix these issues.
@Carlosabc819 I think, you fixed the squeal but you are having low signal volume into the amp?
Do you think you could sketch your rig and upload it, just taking a photo of a piece of paper would be fine to understand how things are connected and powered.
it’s great you have the same gear too.
