Im not very good with delay as just adding a touch to your sound. I have a dd20 and its just a bit much for me right now. Im looking for one of the smaller pedals that takes up less space, and stays simple for doing what I need. Ill really only be using it for that david gilmour, coldplay-ish, etc. delay, nothing too extreme. Should I be looking at the DD3? DD7 or whatever the newer one is? What were the advantages of the old DD5? Just looking for help getting started here, hope I explained what Im looking for. Thanks.
