I am looking for a new wah pedal at the moment, or a delay. But for now WAH

I can get a good deal on a Vox V847A wah, But ive heard it doesnt cope well with high gain soloing. (On ebay, Cant try it out)

I am looking for a wah sound similar to what dave or ad use from Iron Maiden, somewhat smooth, I wont use too many buzzwords to describe the sound I am after.

So should I get the vox? Keep looking?

Anyone make another recomendation please.
Uhh a few more high gain suggestions

Slash Wah
Crybaby From Hell
Zack Wylde Wah
The gear:

* Epiphone Les Paul Custom
* Schecter Jeff Loomis Signature 7 String
* Fender Squier P Bass
* Blackstar Stage HT-60
* Original Crybaby
* EHX Small Clone
* Boss DD-3
the slash wah is really nice, personally im waiting on the kirk hammett one but i dont think it will give you the smooth sound you want.
the slash one is my pick for you
