I'm hoping someone can shed some light on this issue I'm having as I've never heard of anyone suffering from this particular problem. I have an Alvarez acoustic guitar that, when I plug it into anything (an amp, an interface, a PA), the sound comes out alright EXCEPT for the high E string only. I've changed out cables, switched out the battery, tried multiple different devices and nothing changes. Anything I play on the high E string, whether it's part of a solo or in a chord, simply does not come through. Why is this happening???
