"Here is a beautiful Moog Model D Minimoog from 1972. The serial number is 1735 making it the 735th minimoog made. I’m the second owner and I bought the synthesizer from a friend in 1982. I don’t think that he took it out much from his home studio. I never took it out of my studio except to move to a new studio location. The unit is in (want to say perfect) extremely good working condition and very good physical condition considering it is about 44 years old. My tech and I went through the unit to physically align the keyboard (many mini keyboards are really wavy, guess I didn’t play this one enough) and to clean the connectors for the pitch/mod wheel section since the Glide switch would occasionally stay on, but now works correctly. Other than that we couldn’t find anything else wrong to fix. Th synth stays in tune and doesn't drift. Included is a heavy-duty flight case, which I refurbished with new PE (polyethylene, the good stuff) foam to make it like brand new inside. If you check the sold minimoogs on ebay you’ll see a range of sell prices up to and over over $6000 or more for ones of this vintage. $4495. Don’t be afraid to shoot me an offer."
