The EWI SOLO features 200 sounds and is perfect for portability with its 12-hour battery life. I purchased this used on Mercari about six months ago. I don't use it much, just practicing occasionally, so I'm selling it to raise funds. There are no issues with the operation, and I think it's in good condition. The mouthpiece has been wiped with alcohol, but if you're concerned, please replace it with a new one. Included items: - Main unit - Strap - USB cable - User guide - Start guide (for EWI4000, 5000, with CD) Thank you for looking.
