Hello, I just want to know which one should I get I been really interested in the sound and tweakability of the axe fx 3, fm9 and fm3. I want to know what the differences between them are and what you feel is more worth from your experiences. I know the axe fx 3 will need a foot controller so I'm willing to spend if worth. I mainly play progressive metal so I'm interested to on how the effects and amps sound is between them.
