If you are playing at loud volumes the problem could be related to model select knob slightly moving. This can be caused when you use a preset on the amp, the physical location of the knobs is ignored and the preset is loaded. If you are playing loudly it is possible that vibrations caused by the low end could make the model select knob move, when it does the amp model will snap to wherever the physical knob is set to. This can be fixed by parking the knob at either 0% or 100% and reloading your preset.
If you are still having trouble, check your connections between your FBV controller and your amp, look to see if the FBV ports are damaged at all. You can also try replacing the CAT5 (Ethernet) cable with a fresh one.
Let us know your results.
