# Moog Opus 3
“Up for auction is the Polyphonic synth the Moog Opus 3! This unit is fully functional and has been serviced by an old Moog technician from the factories. The initial foam put in upon the release of this unit HAS BEEN REMOVED! YOU READ THIS CORRECTLY!! Moog originally put a foam in the unit to prevent dust and other things from entering the unit. Over time this foam would turn into a tar like goo. THIS HAS BEEN REMOVED. I also took the time to get it serviced and clean up all the sliders. This unit functions like a charm. It comes with the original owners manual. I am selling this unit because I am not a keyboard player and am planning on purchasing a new guitar amplifier for my most current music project. Since I never played this very much, the unit is in fantastic shape.” Link
