Even though it is used it is very clean and in great shape. It has been tested and seems to be working as designed. It shows normal signs of gentle use for a unit this old and nothing stands out as an issue to be concerned about. Input & Output jacks look like there is some oxidation built up so some contact cleaner might be needed. Please look at all of the photos to see the condition of this unit for yourself and please message me if you have any questions before making a purchase because there are NO RETURNS ON USED VINTAGE EQUIPMENT.
The R1000 is Yamaha's first real entry into the market of digital reverberators. In 1983 analog reverbs such as springs and plates were still cheaper than digital machines, but didn't offer much customization at the lower end of the market. But this unit finally promised customizable digital echo at an affordable price (Roland presented a similar device in 1983, the SDE-2000, which was slightly more expensive).
Four reverberation modes can be selected, with decay times of 1.55, 1.62, 2.3 and 2.4 seconds. Not many more features other than a parametric EQ.
