Here are some I have in order of preference. Subjective topic, as everyone has different tastes in what sounds best to them.
1) Wizard Wah by RMC (Geoffrey Teese) This one is my fave for the reason that it does not sound overly shrill in the full toe down position.
The full sweep sounds great to my ears. Also, Wahs are all that Geoffrey does.
2) Wizard Wah by RMC (Geoffrey Teese) Backup for number 1
3) Big Bad Wah by Vox 2 adjustable wahs in one. Allows me to dial back the crispy/shrill toe/down sound that I do not like.
4) Crybaby 535Q by Dunlop I like the adjustable options, but when I dial this back to it's mildest settings, the toe down position
is still to shrill for my tastes.
5) Crybaby's assorted by Vox and Dunlop. I have 4 or 5 of these that date back to my first which I bought in 68'. These were bought over the
years to replace it's predecessor because of scratchy pots. Again, the full toe down position was overly
nasally/crispy/shrill. I found myself not quite flooring the toe down position to avoid this tone, but thinking
about not quite going to the full toe down position, was just one more thing to think about when I was
6) Bad Horsie Way to crisp for my tastes.
Again, wahs, and the tone one can get from them using them for a full sweep, or just the "sweet spot" can be a very subjective topic. Everyone has
different tastes in what sounds good to them. I plainly do not like the overly crispy, nasally, shrill sounds that so many wahs produce in the full toe down
position. Amps also can affect this and my amp of choice has always been Marshalls. This is why I like the Wizard wah so much. It has a full sweep that is sounds great to my ears.
Here is one that was done with the Wizard wah.
