I like the small form factor of your Dunlop expression pedal, never been a wah user but would like to use volume and especially morph. Haven't paid much attention to expression pedals to be honest so I'm not up to speed on what's available, do these work well for the above mentioned purposes?
I hadn't used the smaller ones before, but they work very well. I also have a full-size mission exp pedal for my toaster which is awesome
