I've had my Fm9 for a week or so, used it at church this past week. Sound wise, I can't tell a difference between it at the Fm3. I'm starting to think I'll just stick with the Fm3/Fc6 combo and save money. I don't max out my presets, and with the 3/6, I can pair down to a smaller footprint for times when I don't need all the switch options. Don't get me wrong, I do like the Fm9, and the extra outputs are nice. Just thinking it's an expense I might not really need. Decisions, decisions.
