The v847 seems like a good bang for the buck contender right now. The main thing is, for how little I use wah, I don't want to degrade the rest of my signal any more than I have to with the presence of a wah. To get one true bypass modded makes it a little more than I want to spend. Kind of a rock and a hard place.
I would spend another $50.00 and get the Vox V848 Clyde wah. I know for a fact by that the Vox V847 sucks tone big time.. It will suck most of the high end sparkle out of your tone.. Spend the extra and get the Clyde, and it has True Bypass, and will not degrade your signal.
