This is a tc electronic Ditto X4 Looper. I bought it about two years ago, but I haven't used it much since I found it to be very feature-rich and I lack the technical skills to fully utilize it. I've only used it a few times and then stored it away. Sound output has been confirmed. Notes: Please understand that this is a used item and is being sold as-is before bidding.
