This Vintage Moog just came from the shop where it had all of the internal foam cleaned out. If you know this style Moog the interior foam degrades and becomes a bit of a mess. This one was completely cleaned and all of the pots where checked over and it is in excellent working condition. The on off power button top is missing and the grommet for the power jack is also missing. The power supply is a replacement but works great. The overall sound of this synthesizer is just cool.
