The Roland Chorus Echo is an analog tape echo, chorus, and spring reverb rack effect unit released in 1982.
The unit features three playback tape heads which can be used independently and in combination. There are also two additional effects circuits that can be switched in and out: lush analog chorus, and a vibey, metallic spring reverb.
The SRE-555 was the last tape echo machine Roland ever manufactured. It’s an incredibly robust and well made piece of equipment and I can’t think of anything that comes close to the sonic and creative possibilities this unit offers. It lives on one of my consoles effect sends and I use it on almost every record I produce and mix.
Here’s a little secret as to why each Space Echo or Chorus Echo unit sounds unique. They have hidden calibration trim pots on the circuit board. These pots have to be manually adjusted with a small screwdriver and control things like signal compression and how quickly your echo will go into self oscillation.
