This looper is really high end. There are plenty of functions all controlled by the single knob. I haven't even fully explored them all. The sound quality is really good. There is basically no difference in sound between the input and output. Loopers are a great tool for layering live tracks on stage, I found a lot of inspiration in my songwriting as well.
Another thing really usefull about this product is the stereo output jacks. I only use the mono input, but the sound still splits to the stereo output jacks, which means you can use a stereo amp setup without buying an aditional ABY box.
The build quality is solid, as to expect from TC products.
I'm very satisfied by this product and I would recommend it to anyone who's searching for a good quality looping pedal.
