usedsonicsix “Moog sonic 6 in good condition. It works but not sure if it’s 100% functional so I will sale for parts. It generates sounds regardless of playing any keys but all keys do react. I don’t know if is something obvious or if it needs repair. All buttons and faders appear to be working and effect and change the sound. One knob has been replaced and all but one of the fader/ slide knobs are missing. The case is a little rough but solid.” Link

sonix six “This listing is for a Moog Sonic Six Synthesizer, working condition, all controls and keys operate. I don’t play keyboards so I’m sure a setup like this would need service. I played it thru its onboard speakers and everything makes crazy sounds. The plug for the power supply is loose, moves in and out, still powers up, but should be addressed. Also has surface rust on chrome latches and handle. Was stored in a damp family room, inside is clean though.” Link

moogsonicsix “The moog six is in good condition with light signs of wear from normal use. The sonic six is a rather durable device. This one was well taken care and is in good working order. It was originally designed for educational and home use so it is light and portable and even has a built-in amplifier and speaker. This is kind of a rare bird and is seldom seen but in the right environment can be extremely useful and a much welcomed sonic edition to your sound. Comes with manual & power supply.” Link

After 20 hours of work and an invoice of 1740 € ( that will be given) Mr Dierstein gave full life back to this rare Moog Sonic 6.
Works then perfectly
Perfect cosmetic condition
And the case is also, apart minor scratches, in a very good condition both on top of the case and the bottom.
Manual and shcematics are included.” Link

sonicsix “PHYSICAL CONDITION – Very Good: Some slight discoloration, leftover tape residue, minor scratches and blemishes, but it looks very good overall. There are a few non-original slider caps.

WORKING CONDITION – Very Good: Some of the controls are a bit more loose than new, but the unit has just been serviced by a veteran keyboard repairman in Hollywood, CA, and is working very well overall. ” Link

sonicsix “For your consideration this Moog Sonic Six. It just got back from Syntaur here in Texas and is both looking and sounding fantastic. The synth is in great cosmetic condition. I have photo documented the following blemishes with photo’s above. The two sliders to the left of the keyboard are non-original. On the leftmost slider of that pair there is a slight dent in the metal housing along the slider opening. Three knobs are scuffed. All of the knobs are original. The case has very few scratches but the hardware is showing signs of rust. The rust is on the surface and is not effecting their strength or functionality.” Link

sonic six“I purchased this unit 2 years ago at an estate sale. The story is that this u it was once part of the Carnegie Mellon school of music (who also did some work on the synth). It was sold off to a private owner who died around 2007 and I purchased it for his sister along with some other pieces. From what I can tell it seems to be fully working although it sounds like a loose nut that holds the face plate on is rolling around when you tilt the closed case.” Link

Moog, Sonic Six @ 02 March 2015, Comments Off

sonicsix“t has a few issues: (sold as is)

- Most functions of the synthesizer work, but it needs servicing and calibration to the specifications in the included service manual.

- The 4 octave keyboard has failed completely and does not work, it triggers the loudness contour (envelope generator), but does not track any pitch regardless of what key is pressed.

(I have read that this is a common problem, and that the keyboard bus bar contacts have failed and or a failure of a dual FET, N channel J-FET, NF510 )

- It doesn’t have the original knobs, I have installed suitable replacements. Moog knobs are available from Moog Music USA.” Link

recently serviced, including full calibration.

Front panel (the inside) in superb condition

Outside in very good condition.

but note the following minor things. 2 slider caps missing. Ring Mod works, but pot occasionally intermittent. Keys a little sticky. There is one catch missing.

Everything else seems perfect.

sonicsix “I have owned this moog for over 20 yrs. As guitar is my primary instrument this moog has barely been used-well under 10 hours total!!
It is in extremely clean condition as the photo’s show and comes from a NON-smoking environment.
Every knob and slider works perfectly! Not even electronic cleaner is needed-no scratchy pots! Well taken care of. Mostly sat closed and on a shelf.

This can create some really wild, unique and unusual sounds!! Listen to Pink Floyd and you can some idea of how the Moog can be used in general.
Sci fi central for sure!

I prefer to keep this because of the cool sounds it can make that I have yet to fully explore and the rare ANALOG version of sound manipulation.
Few people understand how sounds are created, shaped and interact. Its a living classroom in sound shaping and manipulation! Wild to hear what happens when you take a cool sound and change the shape of the wave only and then suddenly a new sound is created…or some crazy pulse suddenly appears or shifts
Change the rate of oscillation or the relative volume of one of two generators and WOW!!! I reaally hate too sell this….…..”

moogsonicesixUp for sale is my Moog Sonic Six – this synth is really cool for sound making and normal synth sounds since it has two oscillators. It is not in good working order however I don’t believe it would require much in repair costs to get it back up and running. At the moment it powers up and the speakers don’t let out any noise. However, you can hear the two LFOs triggering and modifying the filter when the resonance is turned up” Link

” IT IS IN PERFECT SHAPE AND WORKS FINE. IT HAS A BUILT IN SPEAKER AND A HEADPHONE JACK FOR PRIVATE PROGRAMMING. A QUARTER INCH PHONE JACK LETS YOU RUN ANY SOUND YOU WANT INTO IT FOR MODULATING. THERE ARE TWO AUDIO OSCILLATORS WITH MULTIPLE WAVEFORMS AND TWO SUB-AUDIO WAVEFORM OSCILLATORS. A LOW PASS FILTER WITH REGENERATION, A RING MODULATOR (HARD TO FIND AN ANALOG RING MODULATOR) NOISE SOURCES AND SO MANY POSSIBLE PATCHES FOR ROUTING WAVEFORMS, ENVELOPES AND VOLTAGE TO FILTERS, OSCILLATORS AND AMPLIFIERS. THIS SONIC SIX HAS A MANUAL AND A POWER CORD AND EVERYTHING WORKS PERFECTLY. HAS A FEW ‘SUPERFICIAL’ SCRATCHES ON THE CASE. THE FRONT PANEL HAS NO RUBBED OFF DECALS OR DIRTY FINGER ‘SLIDING MARKS’. NEVER USED AROUND SMOKING ENVIRONMENT.” Link

” I AM THE ORIGINAL OWNER AND THIS SONIC SIX HAS A MANUAL AND A POWER CORD AND EVERYTHING WORKS PERFECTLY. I HAD TO REPLACE A COUPLE OF SWITCH COVERS OVER THE YEARS, BUT I’VE KEPT IT IN IMMACULATE CONDITION. WHEN THE MINIMOOG WAS MADE FOR STAGE SOLOING, THE SONIC SIX WAS MADE FOR STUDIO SOUND EFFECTS AND BACKING TRACKS. GO TO “MOOG SYNTHESIZERS, WICKEPEDIA” AND SEE ROBERT A MOOG WITH HIS HAND ON THE SONIC SIX, NEXT TO THE MINIMOOG AND THE MODEL 35. THIS THING MAKES ANALOG BASS SOUNDS YOU WOULD NOT BELIEVE. ANY TIME YOU MIX SEVERAL ANALOG OSCILLATORS AND CONTOUR THEM WITH ANALOG FILTERS, YOU GET DEEP BASS THAT ANY DIGITAL SYNTHESIZER CANNOT REPRODUCE. IT ALSO HAS A RING MODULATOR THAT MAKES HIGH AND LOW BELLS AND SOUNDS WITH MANY SIDEBANDS. A LOT OF THOSE SOUNDS ARE FOUND IN FILMS , AND ARE NOT PROGRAMMABLE AND UNAVAILABLE ON DIGITAL KEYBOARDS. THERE ARE SO FEW OF THESE AVAILABLE AND SO MANY PEOPLE WANT THEM, THIS IS HARDER TO FIND THAN A MINIMOOG, YET MUCH MORE FLEXIBLE. THE MINIMOOG WAS MADE TO USE ON STAGE AND GET A ‘QUICK’ PATCH . . .THE SONIC SIX WAS MADE TO GIVE YOU THE MOST FLEXIBILITY POSSIBLE WITH SWITCHES, CONTROLS AND KNOBS. THE ONLY WAY TO BE MORE FLEXIBLE IS TO HAVE A PATCHABLE MOOG (MODEL 15, MODEL35) FOR $12,000 – $35,000. BUT WITH A SONIC 6 YOU DON’T HAVE TO HAVE 40-100 PATCH CORDS. HERE’S YOUR DREAM FOR UNDER $10K. HAS A FEW ‘SUPERFICIAL’ SCRATCHES ON THE CASE. NO RUBBED OFF DECALS OR DIRTY FINGER ‘SLIDING MARKS’. NEVER USED AROUND SMOKING ENVIRONMENT. IT IS IN PERFECT SHAPE AND WORKS FINE. IT HAS A BUILT IN SPEAKER AND A HEADPHONE JACK FOR PRIVATE PROGRAMMING. THERE ARE TWO AUDIO OSCILLATORS WITH MULTIPLE WAVEFORMS AND TWO SUB-AUDIO WAVEFORM OSCILLATORS.

“I’m selling this very clean and recently serviced Moog Sonic Six. These are one of Moog Musics rarest synthesizers. I purchased unit was purchased from the original owners sister after his passing. She stated that she had had the synth serviced by a CMU electrical engineer and gave me some left over capacitors. I’ve owned quite a few synths in my life and some very rare and unique instruments and this one ranks up there! I recently gave it a good general cleaning and quick once over. Other than some scratchy sounding speakers( I would think the pots need cleaned) it seems to be working fine. I will personally package it to assure its safe arrival and I will also fully insure it for the purchase price as well. I guarantee this unit will not be DOA but due to its age can’t promise more than that. I have 100% positive feed back and will strive to keep it that way so bid with confidence. ” Link

“RARE, Vintage early 1970′s Moog Sonic Six Synthesizer w/original Power Cord. Don’t know a lot about the unit, so I am selling it AS IS. I did have a musician friend of mine try it out at it and it seems to be functioning well. Keyboard and all controls seem to be working fine. Missing 5 slider control knobs and 2 tiny screws, but they don’t affect the unit’s functionality at all. Nice loud output from speakers but there is very slight damage to middle speakers cover/felt, which does not seem to affect the speakers output. Exterior in decent shape too!” Link

” Zum Verkauf steht hier ein MOOG SONIC SIX , einer der ungewöhnlichsten aller Moog Synthesizer.

Das Gerät befindet sich optisch und technisch in tadelosem Zustand.Der Moog ist seit Jahren in kundiger Hand und wurde nur im klimatisiertem Nichtraucherstudio verwendet.Regelmäßige Wartung versteht sich von selbst.
Einen zweiten in diesem Zustand zu finden dürfte sehr schwer werden.

Der Sonic Six ist eine echte Klangwaffe und deutlich umfangreicher ausgestattet als viele andere Moog-Synthesizer.
Er besitzt Features die sonst nur beim großen Modular zu finden sind.
an erster Stelle wäre da der Ringmodulator zu nennen.Aber auch die LFO Sektion ist recht einmalig in der Synthesizergeschichte.
Die LFO’s bieten eine Vielzahl an Wellenformen, können gemeinsam durch eine interne Masterclock gesynct oder völlig freilaufend und damit unabhängig voneinander verwendet werden. Die Geschwindigkeit läst sich über die Hüllkurve spannungssteuern, was sehr organische Modulationsverläufe ergibt.” Link

“A Moog Sonic Six in decent condition.
It was working when put away a few years ago, but now only produces some hiss
from the speaker. Cleaning out my collection and don’t have time to diagnose.
It sounded great before it got put away.
It is pobably an easy fix, but Im not sure.
Therefore, it is being sold AS-IS.

It is missing some of the screws holding the keyboard in place.
4 of the slider knobs are missing (they were gone when I got it).
The slider posts are intact, so all functions are useable.
Case shows expected wear

Serial Number is: 1971″ Link

” Hello,up for auction is a Vintage Moog Sonic Six synthesizer. It has been thoroughly cleaned and checked and is in perfect working order. This is an absolutely unique item with a very interesting history. This is the last brand new Moog synthesizer in existence, the last new Moog to leave the factory, and the last Moog Sonic Six synthesizer ever produced.

When Moog ceased operations in 1993, Tim Smith and Dave Weyer , on a tip from Tom Rhea, purchased the remaining inventory from the Moog factory and had it shipped to Montana. The inventory consisted of one completed Sonic Six unit , three that had failed quality control , owner and service manuals ( I will make a copy and include these ) , some circuit boards and power supplys for various models including the MemoryMoog , MultiMoog , PolyMoog , and several boxes of miscellaneous parts. Moog stopped production of the Sonic Six in 1979. The Sonic Sx listed here , the last completed unit , sat on the production line until 1993, and after leaving was kept in Tim Smith’s warehouse until his passing in 2001.

Tim Smith was the Western Regional Tech Rep for Sequential Circuits , Arp, Moog and also contributed to the famous Vintage Synthesizers book and articles in Keyboard Magazine. Tim was an expert at repairing all kinds of synthesizers and electronics and over the years became friends with many notable synth designers and gurus ; Bob Moog , Tom Rhea , John Simonton , and Stanley Jugleib to name a few. Dave Weyer is more well known as the amp guru at West Coast Organ and Amp in Hollywood California . His amplifier mods and repaiirs were enjoyed by many well known musicians including Neil Young, John Lennon, and Jimi Hendrix. Tim and Dave also happened to purchase the remaining inventory of Arp and ElectroComp the same year. ” Link

“This is a Moog in suitcase. A synth designed by MuSonics and worked on by Bob Moog. The X/Y LFO’s allow you to create layers of modulation that ad depth to any sound. The filter sounds amazing; I have never heard a filter oscillate as loudly and smooth as this synth’s. This synth was fully restored by one of NYC’s finest synth repair shops. I have a receipt from August 2013 that shows this synth was fully cleaned, calibrated and tested 100% functional. The speaker was even replaced with a newer, higher quality speaker that sounds nice. The speaker is great for coming up with sounds in your room, or taking the synth over to a friends place to write music. This synth has ring mod, separate outs for the pre-filter oscillator signals, oscillator sync, the LFO’s can trigger the oscillator… there is so much this synth can do that even modern analog synths don’t tackle.” Link
