I have the Harley Benton version, which is exactly the same unit; just rebranded. 8 loops, midi out, 2 switching options and tuner out all programmable, what more do you need? Great value for a great product. I've read about popping issues, but I haven't had any. Most popping issues have to do with the pedals you hook into it. A simple 1m resistor on the input jack of your pedals could solve this though. Now I feel like a guitarplayer instead of a tapdancer.
great value switcher unit, fully programmable that will control your whole board... except rocker pedals like wah and volume rocking function... check the spec's online!
something that does what this unit is capable of would have cost $1000s a few years ago. great value and controllability!
