"Single owner, been on the road in the 80's and since then has been in temperature and humidity controlled environment. This was purchased in early 1976 and from what I can tell it is a 1974 model. This unit has all original parts (including owners manual and sound charts) with the exception of the OSC 2 frequency pot. It does have that fat, analog sound that Moog is known for.

There are a few dents and scratches - one in particular(see pictures) and a number of smaller bumps and scratches.The keys show some wear-normal usage and the A4 and B2 have small cracks (hard to show in picture) The keys have fair action but could use some work. Most notably, the contacts on D1, G1 and F4 don't always make a solid connection and the pots and switches are a little scratchy, they may just need a good cleaning.

As with many Mini's there is oscillator drift. In this case it is pronounced. If allowed to warm up for 15+ minutes it will stay in tune for short periods of time.The issue is OSC 2, OSC stays in tune pretty well but also shows some drift.

The pitch wheel is cracked and while it functions, it is not smooth and the pot needs to be replaced. The modulation wheel is unresponsive and this pot also needs to be replaced. The OSC 3 Control switch is intermittent and overall modulation seems to be tied to the bad pot on the mod wheel."
