I bought this after a lot of searching for a dual channel reverb I could chain. Overall, the feature set on it are... well mind-blowing. I'll never use them all. It's a good unit, and it sounds great.
I'm giving it for stars because
1. They could have added a USB interface to help you dial in and save presets. There is a lot of features, and that would certainly be useful
2. When both reverb channels are on, the volume for the whole output increases. While it's not a deal breaker, it's very noticeable bug. My research has indicated that it can only be fixed in factory. Again, with point 1. it would be far better to have a USB where this could be fixed with a firmware update!
