Plastic housing, bucket brigade with a very very low delay time (like 200 and some ms). Stereo.
Simple to use.
I love old delays. My favorite is always the same: the old Maxon AD900.
Arion ... How to tell? it blows, it blows ... too much. The delay time is also very low. Delay to use especially for noisy trips, or else very moderate dose, the setting for a reverb effect.
Vintage delays still abound, and it is sometimes interesting to enjoy. He may be a delay extra interesting to have ... However, beyond the 50th I really hesitate to buy this model!
