Funny this comes up now. I played at a small honky tonk in a small town and used my z2200 Logitech. It was just kinda muddy sounding, not clear as usual and I had it maxed out! I've never had it maxed out. I suspected the power was dirty. They had several big fans running, including one industrial box fan three feet behind me. I got through it fine and got hired again but it wasn't ideal.
