It's a very good pedal, especially because any better option is also considerably more expensive. Also, the tracking depends a lot on the way you play, I found that synth pedals need you to adapt to them, rather than the opposite.
The super synth has an incredible range of sounds, but bear in mind that you need to create presets using your PC, otherwise you'll be very very limited. I found this to be quite a big issue, as I have no way to bring a computer to the rehearsal space: it took me a long time to fine tune the sounds I created because I played with the band, thought "This needs more bass\This needs more filter\Whatever", went home, changed the sound with the pc software, than had to wait a week to test it again with the band...
