Very low noise, sounds crystal clear. Phaser and chorus disappointing, fantastic delay and reverbs, but I don't know how to reallu program the beast. It's definetly the best choice if you have to work with ONE processor. I will buy it again if I had too. But once you've made it the flexibility of this box is great.
Every effect has lots of parameters to control.
You have to dive into details. This device is not very easy to handle. Overall quality is very good. This is not a heavy duty stompbox. But I think it's ok even for gigs.
