This is an EP-2 Echoplex that i aquired. Serial Number is 5088. This unit needs work. I am not familiar with working on old electronics so i am not going to attempt it myself and leave it to a pro. Please see the youtube video to see what it is doing. The signal flows through the unit to the amp. The mechanics all seem to be working and the echo works. It just makes a lot of noise as you will hear in the video. I would guess maybe it need...s new caps or tubes? I have no idea just speculating. Someone familiar with old tube gear may know right away what the problem is when they hear the video. At any rate i am starting this auction at $450 and will see what happens. It did not come with a foot switch. Also, it looks to me like someone worked on it in the past as it has a 3 prong cord. I'm assuming these old units originally came with 2 prongs. Also, the 4 screws that hold the unit into the chasis are missing. Not from me...that's just the way i received it. I can take it to the hardware store to try to find the right sized screws if the buyer would like...i just don't want to mess anything up with non original parts. Thanks for looking and feel free to ask any questions! I only ship in the U.S.A. Youtube link https://youtu.be/L0GGGlzDO0w
