T.C. Electronics Ditto Looper
"DITTO LOOPER simply loops, and it does it really well! It’s ‘one knob’ button may seem like a minimalist approach, but all the essentials are there: Record, Undo/Redo, Stop and Erase are all accessed via different foot commands that always make sense, whether you are building loops, changing from one part to the next (we’re looking at you, live performers), or adding layers to a song.
DITTO LOOPER was designed from the ground up with guitarists in mind. Hey, we play too, so it just made sense. We made sure DITTO LOOPER takes up minimal space on your board, but still has the essential “make your guitar-heart jump” features, such as True Bypass and Analog-Dry-Through to ensure your tone remains uncolored."
