Go for Edder's mods.
The fasels are quite a radical change from the stock crybaby tone and there's 2 tones there, the red & yellow.
you can even have BOTH installed, selectable via toggle switch.
Heh, yes, Keeley has a mod like this but $450 for a modded Crybaby/Vox wah? I'll get Teese's RMC wahs thank you.
The pot is also an important component of a wah's tone... Had a stock Vox and a modded Vox, same models... modded had true bypass and a Fulltone pot... the modded one sounded more natural and pleasing to the ear.
