This is a high-function looper/rhythm machine, but more affordable than Boss. It has two switches, and I found it very useful for tap tempo, recording, dubbing, and redo/undo functions. The quantization feature, which switches recording/playback at the bar lines, was very convenient because I didn't have to worry about the timing of the switch. Both guitar and bass sounds were recorded cleanly. The lights on the switch section are also easy to see. I am selling it because I switched to a larger looper due to an increase in equipment. It was only used indoors with slippers, and it's from a non-smoking, pet-free environment. A Japanese manual is also available online: https://quanta-intl.jp/wp-content/uploads/2024/04/FS21_Manual_JP-ol.pdf The FS21 features looper and drum machine functions. 44.1kHz 24-bit high-quality looper and drum machine.
