I have a Boss DD-3 and a JHS Pink Panther Delay. The Boss is a great pedal, but the JHS Pink Panther sounds a little bit warmer and more natural to me, if that makes any sense, and you can tweak the settings more to shape your delay effect. It also has a switch to go from digital to tape, which gives you a kind of warble. I have also heard good things about the TC Electronics pedals, but haven’t played one. I would recommend watching a lot of demo videos of different delay pedals before you pick one. Nobody really criticizes anything about gear in demo videos, but at least you get an idea of what it sounds like and what you can do with it.
