Just want to give a shout out to Donnerdeal. I purchased the Donner Alpha Force multi effects pedal and I wasn't very happy with the chorus. I emailed them questioning whether or not my unit was defective since the chorus was so crazy subtle. I felt it behave the same as what I had seen in the multiple demos on Youtube. They responded quickly and asked me to send a short video with an example of my issue. I made a short iPhone video and they sent it to their techs. A few days later I receive an email saying they're sending me another unit. They aren't even asking for the original unit back. It was relatively quick and all through email. They were very polite as well. It may or may not be defective. Maybe that's just how the chorus is. I guess I'll see when I receive the replacement. Either way, I think it was great customer service which is rare these days and I wouldn't hesitate purchasing from them again. I really like the pedal and it was about $18 cheaper direct than through Amazon.
