BOSS Rackmount Digital Delay DE-200

This is a rackmount digital delay from the BOSS brand (made by Roland), manufactured in 1983.
I purchased it when it was first released and used it extensively for live performances and home recording at the time.
I remember being overjoyed when this effect pedal was released at an affordable price for amateur musicians, as digital delays were a luxury back then.
I used it not only as a delay (echo) machine but also as a flanger or chorus effect.
I recall its clear sound, unique to digital delays, being very easy to use.
All parameter settings are done via the knobs on the front panel. It does not support remote control via MIDI, but you can synchronize timing using a rhythm machine's sync signal or a footswitch.

Although I haven't used it for many years, I have confirmed that it accepts audio input, outputs effect sound, and that the parameters change when operating the front panel knobs. However, as it is quite old, I cannot guarantee that the sound quality is the same as it was originally. Also, it has been heavily used and is covered in scratches. Please consider purchasing with an understanding of these points.
