Yeah, you gotta find what works best for you. I would just say consider two things about the FM3 before buying. I thought three foot switches on the FM3 would be enough if you can control different pedals in different presets in stomp mode, set per preset (programmable like Helix)…. You can’t (at least no way I can find)!!!!!! THEY ARE GLOBAL meaning when you set Stomp 1 to “drive 1” in stomp mode it is always drive 1, even if you don’t have a drive pedal on that preset… that stomp then becomes useless when in Stomp mode for some presets. With the FM9 many people set it so the top right three stomps jump between presets, stomp mode, and scenes with the bottom six then controlling variables in each each (very similar to Helix setup which is awesome).
Also, FM9 can do two amps. Just one amp on the FM3 absolutely sounds amazing with the quality and is truly enough, but a two amp setup sometimes can work wonders for tone and sound. I find that on the Helix, all of the best preset files I’ve downloaded from others online all had a two amp setup, with each amp panned hard to the opposite side. I’m looking forward to trying that on theFM9.
Again, everyone has different needs, so the FM3 could be the best for you, just things to consider….. Best of luck on your choosing.
