Moog Opus-3

Moog Opus-3 Image

The Opus-3 is one great little synth. It was designed by Herbert A. Deutsch from Hofstra University who originally nudged Dr. Robert Moog into building synthesizers and later served as director of sales & marketing for Moog Music. Herb also wrote the owner's manual. The sounds are broken up into 3 categories: Strings, Brass and Organ. Strings and Brass have their own separate VCF (filter) sections, the Organ section has none. The Opus-3 also has 2 sound outputs for an early stereo effect with panning! It's a colorful little synth with clearly laid out sliders and is fairly straight forward. It has classic analog Moog sound quality and is a great source of some string and lower octave techno-organ sounds. It is used by Stereolab, Kraftwerk, Zonetech, 808 State and The Rentals.

I have seen a few on ebay go for from $900-1000 if they are in decent shape & around $500 if they have issues with dead keys, one of the voices not working, and/or the filter section not working. Honestly, for what it does & the sounds it can create I would say pay whatever you can afford to pick one up. It is an amazing machine that sounds really different than the other Moog offerings but still sounds distinctively Moogish. It can sound smooth & sweet, deep & punchy, or piercing & squelchy if ya wish. And really for a polyphonic moog (sure it's divide down), under a grand is a steal. Get it!

YES, mice indeed. When I bought mine, there had been mice living inside, with candy bar rapper, mouse droppings everywhere, and the black dried urine mixed with the gooey black cushion material that turns to TAR!! After a gross of Q-tips and a putty knife, and hours of cleaning, this synth is Great. Lot's of fun, and great sound. Any thoughts on contact cleaner to improve pitch wheel continuity (not asking for help)?

If I'm not mistaken all (or most) of the sounds can be mixed in stereo. I would love to put this baby through a complex delay patch utilizing the stereo function.

Not only my first synth but my first instrument. It sounds unlike almost any other Moog (correct me if I'm wrong here) and has a lot of potential. I put it in storage when I moved to New York and when my Dad brought it out the innards had been ripped apart by some kind of a critter, presumably a mouse. It was pretty much beyond repair and I sold the case to a local synth enthusiast. Fortunately they go for less than a grand on Ebay and the Moog Opus 3 will be mine again!
