Fine grained
I knew the predecessor of this pedal from back when i was a teenager, so I was amazed that I could still buy the newer version. It's quite hard to say what the pedal does to your sound, but it just makes it feel richer and brighter (not only for clean, but also for distorted sounds). When it comes to changing settings quickly, I have the same issue as with other pedals, that you should mount it actually somewhere on 1m height in order to be able to change settings and not just turn it on/off which you can do by foot.
