I don't know abou tthe bass wah, btu my normal crybaby is reliabel and the company have a good reputation for wah's, so i'd think it's good.

yeah im sure that ones great, i use an Ibanez Weeping Demon for bass though, it has a switch on it that optimizes it for basses and it sounds pretty badass.

You can get a regular and just switch out a capacitor and use it as a bass wah.
