Archon + G Major 2

If you FFT any audio device you will see 60Hz and harmonics. But you describe hiss, not hum. So 60Hz is not the main problem.

Is this on gain channel or clean channel or both?

I am using the Empress Buffer+ with good results. I have a Fractal FX8 on the way to see if it is any better... With the empress you have a good boost that is needed for the lead channel

The FX8 doesn't need buffers in my experience. It's a great piece of gear, though in the end it wasn't for me. I recommend humbuster cables per their recommendation. Those same cables work great with the G System as well.
