Greetings compadres,

I've been using my M9 in my effects chain through my Fender Deville for live performances and it's worked great...but I tried patching it in for some late night recording and was shocked by a horrible high pitch noise and this pulsating buzzing sound.

The chain is guitar -> M9 -> M-Audio Fast Track Pro -> Guitar Rig (w/just a plain amp) -> Ableton Live.

Is anyone else having this problem?

Any known fixes?
