I have 4 different presets with multiple scenes for my live rig. My "main" preset and scene I use the Brit 800 mod #34 amp. Out of all of the different amps and configurations I use, this is the one that gives me the most "noise". In my case, I have a problem at a particular venue. At home, our rehearsal space and other venues, I have very few issues. I still get noise because it's a noisy amp, but it's really bad at this one venue. The venue is known for having dirty power. I solved it by plugging in a HumX. 90% of the noise disappeared. I also adjust the global noise gate offset to clean things up when I am not playing. Also, my pickups are hot and pick up a lot of EMI. Like others have mentioned, if you turn your volume down and the noise goes away, there is nothing wrong with your unit. Try switching to a clean amp and see if you have the same level of noise. The noise is coming from the input BEFORE it gets to the fractal.
