I'm selling this because I bought it as a portable instrument, but I couldn't enjoy it like a regular guitar. I purchased it about a month ago, and it has no noticeable scratches. It has seven frets, each with a three-stage touch panel. You use it by setting chords on your smartphone. You can play chords with your left hand and notes with your right hand. I enjoyed it to some extent, but the freedom is somewhat limited. It's interesting that you can play guitar, piano, and drums all by yourself. If you're interested, please consider it. I can't find the included USB charging cable, so I will include a cable I have on hand.
