Expression pedals

Anyone know of a good expression pedal that is compatible with the line six m9?

Boss makes a decent pedal. Can be used as a volume pedal or exp pedal. Also the new thing out right now is the mission exp pedal. Bad thing is it cost $200!

I have an M-Audio EX-P that I use. It's range adjustable, has a polarity switch and it's priced right at 29.00 anywhere. It's plastic but pretty well made and will withstand all but the more brutal assaults

The Boss FV-500L is a great option--you can also use it as a volume pedal (obviously not at the same time), and it worked great with my M5 when I still had it.

It might be a bit big for some people, but it's bulletproof

Have you tried the mission expression pedal with any of the m series?
