Thank you for viewing. This is a Roland RE-150 with adjustable echo effect. I have confirmed that the power turns on and the tape runs. I am not familiar with the usage, and I do not know the details of the effects, but I have confirmed that sound is also produced. This product includes the main unit and what is shown in photo 13. Thank you. - Model Name: RE-150 - Brand: Roland - Function: Echo Effect - Controls: Repeat Rate, Intensity, Echo Volume - Input Terminals: Instrument, Line, Mic Input - Output Terminals: Echo Output, Direct Output - Power Supply: AC Power
