Any equalizer can do this, especially easy with a parametric EQ.
Ibanez WD-7 to be specific.P-E-D-A-L
I was thinking a wah was just a tone control with a pedal, is there anything special I don't know about?
get the cheapest crybaby you can find. pull the tredle off, set the pot where you like it and just use the on/off switch.

Just one song? For a Scorps solo? Rock You Like a Hurricane, I'm assuming. Forget about it. Just something else to sit in the chain that in all reality, doesn't need to be there. Nobody listening is going to care. But if you must, and you a have crybaby already, adjust the pot to the gear so that when it's engaged, it's already half-cocked. Cost = Free.
That sounds too real, simple and effective for a guitar forum reply.
What is the boutique version of that solution?
The exact same effect can be produced with a graphic EQ.
