Great first impressions. Even after reading other great reviews, it still exceeded expectations.
Great build quality: Pedal is small, and I worried about it wanting to turn over when cables are plugged in, but it has a nice heft and feels great under your foot. The rubber on the dials is a nice touch, and the dials themselves feel smooth and well constructed.
Tones: Exactly what you are expecting. I doubt anyone is going to single this pedal out for having outstanding tones- but the tones are perfectly workable and it has a pretty good range of sounds with the simple controls given.
May be checking out more stuff from Donner in the near future.
