The MXR M82 seems really versatile, but I never played with one. That said, on YT there are several good videos.
Months ago I got this
https://www.gear4music.com/Guitar-and-Bass/Eden-CaliforniWAH-Bass-Wah-Pedal-with-PSU/4UX6 And I am happy with it.
It's still on sale.
It seems less versatile than the MXR, but nontheless it has personality. It is dirty and squelchy if you want, but goes low as well with the right settings.
2 things about it, it wants its 15v psu (that comes with it), and the size.
Everybody thinks it is big, but it is not.
It's as big as a Boss pedal, but sits horizontally instead of vertically, if that makes sense.
