Selling my MOD Duo X unused

hi, I am selling my unused MOD Duo X. It has the on-off button in the back. I bought it and just don’t seem to find the time to get into it.
It’s sad it’s just in the box here doing nothing - best to find someone who loves it and uses it as it should be used. Feel free to ask questions. I am based in Berlin F’hain.
My asking price is 400 Euros ex shipping. Thank you. Esther
