When TC Electronic dropped the Ditto Looper in 2013, it was a lightbulb moment for musicians seeking a straightforward, no-frills solution to their looping needs. While most loopers on the market were adding more elaborate features and more detailed controls, the Ditto took a simple-is-better approach focusing on just the core looping function. One knob for volume, and one switch for everything else -- that's all it takes to get looping with the best of them. All the Looping You Need, Nothing You Don't This small footprint stompbox has a single knob to control the volume of your loops and one button to record, play, stop, and more. Click once to start recording. Click again to start the playback. Click twice to stop it. Click twice and hold down to erase and start the whole thing over. You can also undo and redo by pressing and holding the main button. Even when powered off, the Ditto actually retains the last loop you recorded for when you're ready to start playing again.
