  3. I bought mine from a pawnshop back in the 80s.The guy working there couldnt get it to work, I saw the light flashing and knew it worked, I offered him 20 bucks and said it would look good hanging on my wall.So I got it for twenty bucks hooked it to a nice FX box and have been happy since. it is nice to see some of my equipment iis worth some bucks after all these years,cause I cant get squat for anything else.Imhave since sold my DX 7 a big mistake by the way, oh well..that is my story..peace love amd light…I am Olaf
