I purchased this on Mercari about six months ago and used it a few times before storing it at home. Operation has been confirmed. I bought it for 19,000 yen. I will ship it in the box. Only the main unit and box are included. The following is a quote from the listing: --------------------------------------------- This is a Switchcraft DI. I mainly used it for live performances with acoustic guitars and for home recording. I used it for 2-3 years, but I usually left it connected, so I think it doesn't show much wear and tear. I liked the solid build, which is typical of USA-made products. I think it's also recommended for acoustic guitars, basses, and vocalists. Regarding the sound, I haven't compared many DIs, but I remember being impressed when I first brought it in from the DI provided by the live house, thinking it was the sound of America (?). I'm selling it because I no longer play acoustic guitar. The box is included. Thank you. 【High-Quality Direct Box】 The Switchcraft SC800A is a high-quality direct box designed for active instruments.
