I'm just starting to delve into the capabilities of the VE-500. I was a bit put off at first with controlling the unit from itself, a heck of a lot of paging through options on that tiny screen. But the editing software makes it a breeze to program whatever kind of effects you want and save the patches. Very powerful! I'm extremely pleased with this purchase, and even more pleased with Sam Ash as a vendor. They listed this item as "used", but it came in the original packaging with everything inside (manual, cables, unit, etc.) all in original plastic packaging. Way to go, Sam Ash!
