Where can I get a Roland Space Echo serviced in Los Angeles? I have a RE-201 Space Echo tape delay unit that I've owned for 25 years, and never had it serviced. The pots have gotten scratchy, especially the intensity and echo volume, and this causes the echo signal to drop out sometimes when you turn them. Does anyone know of a good repair shop or person in LA who can do a general tune-up and maintenance on this device? It's served me so well over the years, I think it deserves a spa treatment.
