I'm fairly sure you can't, I'm afraid. I've just tried it and couldn't map the pedal (via the sustain input) to the Kuassa Effector wah-wah. I'm no expert at all, so, maybe someone can tell you otherwise. There exist adapter boxes but it'd probably be cheaper to buy an old midi keyboard with an expression input. https://vi-control.net/community/threads/keyboard-has-no-expression-pedal-input-help.121727/

Thanks for the reply's guys, I will be checking all of them out. Especially ElMoreno's suggestion, Kuassa WahWah Filter (Efektor WF3607), which seems to be popular.

 

Hmm. Isn't the Efektor just a glorified auto-wah?

Or is it foot controlled?

It does both. Quite well, several models of filter to use, great tweaks. My go to, although I do like a couple of the Amplitube wah pedals

 

Well, my, that's the one I was gonna try
Don't scare me like that again, WILL YOU?!

I'm using the Lehle expression pedal, I can control any parameter in vst's from within my DAW in seconds using the USB output. Flawless. Highly recommended. https://www.lehle.com/en/lehle-dual-expression
