Purchased over 20 years ago. Used only at home and never taken outside. There is some minor rust on the metal screw parts, but there are no noticeable scratches, scuffs, or dents, and it is in overall clean condition. This is an early model with a blue label on the back, and it is an analog unit. It is said that the chorus effects on the red and blue label versions are analog, while the black label version is digital. The warm, analog-specific modulation is appealing, and it gives a clear sound even when the effect is applied deeply, and has a noticeable presence even when applied lightly. The listed item includes the main unit only. Operation has been confirmed, and there is no scratchiness in the knobs. It will be wrapped in bubble wrap and shipped via Yu-Packet Plus.
