I've got one.
Bad things - the wah without the fuzz is sh*t on bass. Admittedly it was never designed as a bass pedal, but even so, it's pointless for just wah.
Good things - with the fuzz on the wah is excellent. Real grindy abrasive wah, like the man himself.
The fuzz on it's own falls into the "not bad at all" camp rather than the "brilliant" camp.
I'm pleased I've got it, but there's no doubt you'd have more options with a Weeping Demon and a Duality Fuzz used together. Or separate.
