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.

The brass section is one of the best things of the Opus 3. I have one and it works perfect. It's just amazing. If anyone has one with some section not working good, you must send the opus to a electronic technician, maybe the tension it's no coming to the section. And if there anyone who wants to sell one, just let me know. Here's my mail ejd_ssv@hotmail.com

I've worked on these in the past and have on eon the bench now. It was an export version and would not run on our 110V power. The original transformer can be configured to run on 110 or 220 volts and was easy to change over. See www.technicianlarry.com

This is a brilliant synthesizer--perfect for warm, psychedelic, fuzzy textures. The organ is fairly realistic sounding too and a pleasure to layer. On this track, I use it for the lead sounds and the vintage organ sounds: http://boyeatsdrummachine.bandcamp.com/track/exhibition-b

Loved playing and composing on the Moog OPUS 3 - the string section fed through a phaser sound great live. It's sitting at my feet as I write this ! Some of the sliders need a bit of repair though. A great instrument. - ian.

I first played a borrowed Moog Opus III in the 90s. The brass didn't work, but the strings, organ, and VCF did... and I was amazed how one single instrument could sound like all the early Krautrock LPs I loved - it would do Tangerine Dream's "Zeit" and "Atem" single-handed, even down to the widdly EMS noises (thanks to the LFO and resonant filter); it would do Klaus Schulze's 'Blackdance' and 'Irrlicht' all by itself - well through a reverb guitar amp, anyway.

And put the strings through a Small Stone and a delay and you DO get the Jarre 'Oxygene' / 'Equinoxe' sound.

A few years later I owned one: still works perfect, and it won't be for sale!

A unique machine.
