I'm selling this because I no longer use it. I was using it for live performances, recording, etc. until about a month ago. There is some dirt due to aging, but there are no major scratches. I will clean it as much as possible before sending it. - Model Name: Model 12 - Brand: TASCAM - USB Connection: Yes - Bluetooth Connection: Yes - FX Function: Yes - Sub Output: Yes - Main Output: Yes
