A friend gave this to me way back in the early 2000’s, I used it a couple of times and then it’s been in storage, the unit had a prior owner that had left it in the current condition, though its not too rough considering its age.

Based on the internal electronics (see pics), this unit features the desirable Panasonic MN3007 bucket-brigade analog delay chip located in the top-left corner. Combined with the vintage upright logo styling, this confirms a manufacture date of circa 1990.

Additional Note: this specific graphic style represents a transitional moment for DOD, colloquially referred to by collectors as the "FX-era update" or "Generation 2" aesthetic.

I've just tested the unit out and it’s working beautifully; battery compartment holder is in great condition as well as the interior (refer to pictures).
