The signal coming to the amp is OK. Leaving the amp it gets bad
That's why I was asking if the amp is getting power or not. If the amp has lost power it actually makes the signal worse. I'm always amazed at how many think that if the amp is unplugged, it just bypasses or is a straight through signal.
Very few amps out there have power indicators (other than the Electroline brand, which IMO are the best) so you will have to check the receptacle.
