What to add to a Wah?

[Focalized]

I was thinking of adding something small to build into a wah. Probably just a good drive that works well with wahs. I'd have it on a toggle so that it can be on or off when I turn on the wah. Maybe something more experimental? It can't be too big on vero.

Could just do a buffer...you can add a DPDT etc. to the HEEL position to switch when you rock back, if you were to put something more 'exciting' in there, like a drive or booster.     I set my wah to be just SLIGHTLY louder than unity when it's engaged, to sorta make it come thru a little better - seems to be a nice mod.

How about a trem in there??
