My main problem with them (particularly that one) is it's too complicated. I want to be able to tweak my chorus, well I'd have to flip through a few digital menus to just get anything close to it. Then, GNX has the patches so if I want to tweak it slight to use, I'd have to flip through menus to store just the 5 point change. With only 65 savable presets, I was at 50 before I even got into the other pedals. Also, you can only be using about 5 presets at time without having to bend over again.
If I am going to bend down to change something, I might as well use the single pedals.
The good things about it are the looping feature, the recording abilities and the fact it's a pretty good practice board.
