Yamaha REV 7

The Yamaha REV 7 is a rack-mounted digital reverb unit which was released in 1985. It has 30 reverb presets, a variety of echo, delay & ambient effects, a memory for up to 60 user programs and adjustable reverb parameters (reverb time, room size etc.). The reverb also has MIDI control to recall programs.

Tony Banks had a REV 7 for effects processing on his synthesizers and equipment: he felt it "makes an instrument find its space", and was more versatile than the AMS RMX-16 on keyboards. The REV 7 was especially useful for enhancing sounds from the Yamaha DX7, which Tony felt sounded crude and naked on their own.
