Oliver DD-1000 by Delta Araucaria
12bit digital delay, 1985-ish. Mine was a gift. Made in Brazil under license of Roland Corp., so I guess it's sort of a DEP5 knockoff.
Features: 9 tempo presets ranging from short flanging up to 400 ms, some fine tuning, as well as gain/tone knobs, bypass ftsw, modulation bus (don't know what's it meant for, maybe keying since I got no output from there). Borrowing the "1176 secret" you can combine some of these together, but idk if it actually subtracts or sums these values.
Sound: VERY fuzzy but blends well esp. post-EQ - mine has a loud hum so it's a must, it lives in my mixer's last input channel. Doesn't sound good on its own neither in some mixes but love it for some lofi, kinda Creedence's vox n' snare echo! No plugin can quite match it.
Phisically: 1RU, kinda deep and heavy (beware bent/cracked rack-ears), intuitive knobs though a bit shallow/buried into the faceplate. Has no input/clip nor output LEDs, but whatever, it distorts full time.
Veredict: a tough memory from PA users, and i think in no way it would be looked after for studio use back then. But fwiw, it's worth a try.
