I've had both and now I'm using a Dunlop Dime From Hell Wah. I guess I went full circle because I started with my old Cry Baby.
To answer your question, They are both good wahs with subtle differences. The Clyde is very similar to the CryBaby with only slight differences in nuances. The deluxe has some variable controls on it. The Picture Wah had unusual pedal travel that felt loose or something and the switch would get activated often by accident although it may have been just the one I had. My advice, try them all. They are very subjective and until you try them out you won't know what is right for you. They do sell really well on Ebay if you want to sell them.
You may want to try the Area 51 wah....great sounding wah, one of the best I've heard and I have owned all them other than the vintage stuff.
For the OP, the Fulltone is definitely cleaner sounding, it almost sounds as if it blends some unaffected signal in with the wah, making for a more subtle wah sound. The Teese is much stronger sounding, and more vocal. Both are great, just depends on what type of sound you want. imo, the Area 51 can come very close to the sounds of both the pic wah, and the fulltone, but offers greater versatility.
Hey Lou. very cool of you for posting all this. Honestly I like the SupaQuack clip the best. but theres something inside me that just supports whatever Geoff is doing. Regardless.. every Pic wah clip I've heard sounds great. Thanks for the recomendation though.
