So I've started running the FM3 as an FX only unit in front of my guitar amp. Clean channel on the amp is fine, but when I hit the high gain channel there's a ton of low pitched buzz. The buzz is not there when I run the guitar straight into the amp. Just thinking through what I can try to get rid of the buzz. I've tried unplugging everything from the FM3 except the essentials (power, guitar in, headphone out), swapping instrument cables for TRS cables and vice versa, turning off all the blocks (the buzz is there even with the IN and OUT blocks off), turning down the input levels, running a noise gate. The buzz is even there when the FM3 is powered off but the amp is on. Seems like I'm missing something basic.... Any thoughts?
