"This is a great Minimoog Model D, and an excellent opportunity to get a vintage one at a good value, as it's been substantially modified. All the original functionality is completely intact, but it has some pretty fantastic extra features. The modifications include:

Ribbon Controller - Mounted in front of the keyboard, currently connected to the pitch wheel, with on/off switch
4th Oscillator - Square or triangle wave + frequency knob
Modulation on oscillators 2 and 3, with independent "on/off" switches for oscillators 1, 2 and 3
"Modulation Mix" control now blends oscillators 3 and 4
Separate modulation level knob for the noise source
I didn't do these mods and I don't know who did. The osc 3 + 4 modulation mods appear to be a DIY version of the common Rivera mod. I can't tell you much about how they were implemented; all I know is they sound musical and cool, they work well, and they greatly expand the sound palette of the original circuit. This Minimoog is in good functional condition, with the exception of some scratchy pots. The serial number is 5297 so it has the old oscillator board.

The keyboard holds its tune reasonably well; not the best I've used but certainly not the worst. Scaling is good and usable but not perfect. The bus bar seems clean and good, and all key contacts seem to work reliably. Cosmetically it looks pretty good, but it's definitely not in mint condition. As you can see, some of the finish on the wood panels has worn off, several of the chrome knob caps are missing, and there's a crack in the wood at the top of the control panel. Also note that the frame was cut below the keyboard to accommodate the ribbon controller, though it was done quite nicely and certainly doesn't impact the structural integrity of the keyboard. There is some other minor wear, so please look closely at the pictures; I've tried to be as thorough as possible. It will ship in the blue flight case shown in the pictures.
