I'm having a lot of issues with the noise floor on the Axe I/O amp output. As soon as I plug a cable in it gets a very prominent buzz. The ground lift function is working as intended as without it enabled it gets much worse. This occurs even if the unit is powered off and mothing else goes to it.
It's the same level of noise as if the instrument cable was open on the instrument side, like the unit itself has no shielding.
Is this normal? Anything I can do to mitigate? This funcitonality is not valuable as is.
Thank you.
