Thank you for viewing. This is the TASCAM scratch control unit "TT-M1". I purchased it a long time ago. Includes the main unit, original box, mounting bases x 3, screws x 2, and instruction manual. The box and manual have stains and wear. I haven't been able to confirm its operation as I don't have the necessary equipment to test it. Please ask if you have any questions. Please purchase with the understanding and acceptance of the above. Please understand that this is a personal assessment and inspection. Please refrain from purchasing if you are overly concerned about details.
