For me, just one type of pedal doesn't work. I need a long travel (I use a modded Ernie Ball VP JR) for things like volume swells, univibe speed etc, and then I need a traditional Crybaby/Vox style wah (which I like spring loaded) because the shorter travel works better for fast quacky wah work. Then I use a third pedal, which really isn't a pedal, but a momentary piano style sustain pedal, which depending on the preset and the dampening, will go from full on/off over a given interval of time, and/or range. Sometimes for wah/filter type stuff, staccato effects etc I like just tapping/holding this pedal. I can go from say 0-50% with a tap, and if I tap and hold a half second I can go 0-100%, depending how its set. Opens up some creative options for smooth linear sweeps and such I can't do with moving a normal pedal. Also is cheap and compact.
I had the EV-1 and its great, but found it was a little big for me, and the travel is nice and wide, so great for swells etc, but way too much physical range for a fast quacky wah workout. Likewise, for pitch/whammy effects I enjoy the spring feedback and how it goes back to pitch when I let up my foot.
Not to knock the EV-1, but for what I paid for mine, I bought a Mission EP-1 spring loaded as a B stock, thus cheaper price, and 2 JPVr's which has scratchy pots off Ebay. Put new linear taper pots into the VPJr's, painted them black, and they, paired with my EP-1 and sustain pedal give me all the more control I could ever desire, and for a pretty minimal price.
You can program scenes up with one effect on, on off, and use the same pedal for both, and that works, but I personally just like minimizing that need, less to remember. I like my EP-1 always being a wah, unless its a special patch and its set for whammy. I like another being a uni-vibe speed, so then I can always control that, or step on the wah.
Sometimes less is more, but I think when it comes to direct expression control, more isn't just more, but options and ease of use
