Roland DC20 analogue echo

The Roland DC20 Analogue Echo is a vintage delay effect unit from the 1980s. It was used by many famous musicians, including David Gilmour, Brian May, and Eddie Van Halen. The DC20 works by taking an incoming signal and delaying it by a certain amount of time. It then repeats the signal multiple times, creating an echo effect. The DC20 features a delay time of up to 500ms, a feedback control to adjust the number of repeats, and a tone control to adjust the brightness of the repeats. It also has a built-in chorus effect, which adds a shimmering quality to the sound.
