Never did, just listened to 4 videos of it. I like it. Not sure if I love it. Many features, but not sure about the meat and potatoes of it's sound. None of the vids had the mix all effect. That might be the deal maker for me, but a very interesting pedal, for sure. I owned a Mutron BiPhase in 1976 (was a Jr. in High School), so there's an emotional attachment.
