I have an Anthem installed in my Martin D-28, it has worked very well for quite some time. Recently I started having a problem with the guitar producing a hissing (white noise like) sound. The noise is loud enough to have the singer continuously turning around to look!! This is when I turn the levels up enough in order to be able to hear myself play.
I have tried different things, two different amps, one AER Compact 60 and one Fishman Loudbox Mini. I have tried different cables, flipped the phase inversion switch, tried plugging into a different electrical circuit, but still no luck. My Taylor guitar with factory electronics does not show that problem with either amps.
One thing I found is that the microphone's adhesive had become unglued and the mike was hanging in the middle of the body. I figured I have to get this corrected, and as I test I disconnected the mike from the jack, thinking that if the mike is the problem I would remove it from the equation. The white noise still continued, it seems higher when the mix control is towards the mike, even with it disconnected. I am planning on gluing the mike back up with double sided tape and check again.
I found another issue which I do not think has anything to do with the hissing noise. If I touched the cable going to the battery a crackling noise would come up. I found that the connector to the 9 volt battery had a loose connection on the crimped connector that holds the wire. I added a little solder and that took care of that.
I am wonder where else I should be looking at I will greatly appreciate any feedback.
