This is a Zoom G2 Nu. It's a used item that has been stored. The reason for "junk" status is that it doesn't work with an external power supply. However, it can be used as an audio interface by connecting a USB cable to a laptop or similar device. I tested it for this listing. I connected the output to an amplifier and confirmed the sound. All the knobs worked without issue. I understand this can also be used for recording, but I haven't tested that as I don't have the necessary setup. This listing is for the main unit only. No other cables or power supplies are included. It's a used item, so there may be dirt and scratches. However, please understand that it is sold as-is, with no returns or exchanges. Shipping will be via Yu-Yu Mercari. Thank you.
