I have a couple of these and the room verb with the H-Damp button pushed in is pure vibe on a swampy delta guitar part. Reverb not only doesn’t have to be a hyper real Bricasti all the time, it shouldn’t be. This will instantly add a pleasing lower-fi color and grit that would take quite a bit of time to coax out of a plug in.
Also, it has an instrument level input and a dry signal control right on the front next to the other super easy to use knob controls so it can sit on top of your amp or easily go in the effects loop.

Check the demo below to hear the unit!

Because Korg was good people back then, the power transformer can be configured for Japanese or American power very easily with a soldering iron.
Cool!
