This is a wonderful sounding EP-3 Echoplex from the mid to late 70's. This unit was owned by a Nashville session guitarist, and it has been serviced for peak performance. The current tape is in great shape, and it also comes with a brand new EC-1 cartridge from Mr. Echo. Some parts have been changed for the sake of servicing functionality, and the knobs, along with the front "Maestro" badge has also been changed to "Echoplex".
