At the first contact I was a bit disappointed cause most of the features sounds similar to each other. But after many attempts and tweaking control knobs there’s a lot of differences though. As other 9’s series pedals there’s no built-in compressor, so the tone is depend on the way you play. Also, except modulation, many features has sub octave added, so it means that low guitar tunes (baritone or bass guitars either) doesn’t work good - too much bass appears which makes sound distorted. But after all it’s very unique pedal, great for experimental or jazz kind of music.
