I have bought, tried and returned various loopers over the last couple of weeks; Jamman, Jamman Solo, Boss RC-300 and tried some others in the store. Tonight I picked up the Ditto and this one is a keeper. It's responsive, easy to use, can hold a couple of songs or 5 minutes of ideas. The best part, the recorded parts sound almost exactly like the original, not compressed, no high end roll off or phasing like many most of the others I have tried. It's also has a very small footprint on the pedal board. Downside is no batteries for those without a power supply. Highly recommended for working out song parts and just jamming. I have to say I love the size of these newer pedals that use the slim format like the EP Booster and the Ditto. You can cut your pedal board size in half. Just thought I would share.
