This is a set including the main unit and the genuine PSA adapter (no original box, etc.). There are absolutely no issues with its operation. I recently purchased it on Mercari, but it didn't align with the sound I'm aiming for, so I'd like to offer it to someone who needs it. A guitar effects processor equipped with a variety of amp and cabinet simulation functions. - Model Name: IR-200 - Brand: BOSS - Included Accessories: AC adapter - Functions: AMP & IR CABINET Thank you for looking.
