I was a little confused with your description of the connections, but I=20
thought even with your description there may be something you are=20
unaware of so I thought it worth a mention.
With two separate channels there should be no problem at all (assuming=20
no problems or "special" inputs with the mixer), so the fact you have=20
one and it changes with the removal of one input suggests there is not=20
complete independence in this case. Also the fact that it works with two=20
guitars but not with keyboard/guitar would seem to be more evidence for=20
this.
I would check the entire run all the way to the mixer, including the=20
stage box (could have something unexpected in there) and the mixer input=20
circuitry.
