Before the EHX 1440 I had a Boss RC-20 and I didn't liked it. I know that it is a great piece of gear, but I just didn't got used to it. I need a looper that enables me a quick manipulation of the loop, and the EHX 1440 is more akin to my needs, because it allows to quickly shift the pitch of the loop and reverse it. Simply by pushing a button or turn a knob. The option to control the overdubs volume is also great. The sound of the loops could be better, sometimes they loose definition, but I honestly don't mind because of its ease to use!
