I've had a Cry Baby laying around for a lot longer than I like to think. It was fine at first, but it doesn't get used any more because it's noisy. I could replace the pot, but I don't like it enough to mess with it. I got tired of it eating batteries, so I got a Dunlop power supply, which hissed...so it ended up on the shelf next to the pedal.
I liked the sound of it, and recorded with it one time, and it was perfect for that track.
Eventually I got into performing on guitar again after a long stint as a bass player, and as we worked up original material, I kept hearing a wah on one of the songs. I searched around and settled on
a Line 6 Floor Pod Plus, which includes a wah among its other effects (which I also use from time to time during a set). It's convenient not to have to hook up two or three pedals on the chance I might want to use one of them (I play a 335 into a Blues Jr or a Jazzmaster Ultralight, usually).
It has a good range of sounds, but it dies if when you back it off all the way to the bass (heel) end of its travel. Still, there are no batteries to replace, and it appears robust. I've had it for about a year now, and I'm happy with it.
There may be better sounding wahs, but at this point in my life I prefer easy setup to ultimate tone -- at least, playing live, where it all blows past your ears into eternity anyway.
