Only limit I see is if you want to load up a preset to the max. I can load up an Axe III preset and pretty much have it all. With the FM3, I have no problem having bread & butter presets for Fender, Vox, Marshall & Mesa's (Wah, Phaser, OD, Amp/Cab, Chorus, Flanger, Rotary, Delay, Verb) then creating specialty presets for certain songs or FX. So I'm just using more presets, which is not a drawback at all, IMO.
