I'm looking for a good, general-purpose expression pedal for the Axe2. I don't have an MFC-101 (yet), so I plan on just one EP for now going into the "pedal" jack on the Axe2. Haven't used a wah or volume pedal for years and don't have one lying around. I know that almost "any" EP with a linear taper pot will work. Since the electronic "guts" of the EP won't be used (except for the pot) I know it comes down to personal preference or the "feel" of the pedal. I see some guys using Missions with the Axe2. How do you like them? What other EP's are being used?
