Thought I'd throw in a shot of my new play area, including my EHX 1440 looper.
The EHX 1440 is a nice "step up" looper, with it's most important points being 20 loop storage slots, memory time of 23 minutes, and individual loop fade lengths for each loop. The display is more descriptive than the 720, with items such as fade times indicated in actual number of seconds.
The 1440 has other bells n' whistles like MIDI and pitch control that I don't use, but might be useful for other folks. I'm very content with the 1440 and probably won't find a need for any options other than what it has available.
I've also switched to a Zoom R20 for my multi-track recorder and the play pen now only has instruments That I have made.
