Operation has been confirmed. There's a slight crack in the knob, but it doesn't affect the sound.
Since it is an analog chorus, it produces a warm sound that is different from a plug-in.
There is some dirt such as yellowing, but I have removed the gully and cleaned it to some extent.
Input and output are OK for both front and rear.
Only the main body without box.
Although it is a working item, please treat it as junk as it is quite old equipment.
Thank you for your understanding.
