AB luxury box ...
Very good on paper, very complete, the combinations are numerous and well detailed instructions.

Very easy to use and comprehensive manual

There is something else ... morning breath!
The knobs in the middle level, so neutral, the pedal creates a terrible blow.
Curious by Boss, no curious tester did reported.
I fed with a "Big John" Carl Martin, so given the quality of power supply, is not it.
I use two instruments with one another on A to B, so use very basic with Planet Waves LS2 and without any breath with ... not glop!
Very disappointed.

Not usable professionally speaking.
