One things for sure.....unless you have the correct delay dialed in, you will ALWAYS have a problem with the strum patterns. For instance, Streets...during the verses you hear what almost sounds like a clean 1-2-3-4 type strum. The truth is there are a few repeats on the delay but when strummed to the correct time of the delay actually overlaps so it sounds like its snapping almost. hard to explain (now that I am trying to explain). maybe another edge guy can help me put into words what I am trying to get across.
hope this jibberish helps
