See the original advert for the set in this post.

via the seller: "THIS IS A ONCE IN A LIFETIME OPPORTUNITY FOR ANYONE TO OWN ALL THESE UNITS WITHOUT HAVING TO WAIT YEARS & YEARS TO FIND THEM ALL... IT TOOK ME MANY YEARS TO FIND THEM ALL AND SPENT LOTS OF MONEY ON THEM PLUS ALL THE ELECTRONIC MAINTENANCE I HAVE GIVEN TO EACH ONE OF THEM TO HAVE THEM WORK ALL 100%.

I have 5 units in a robust ATA Molded PE Shock w/ Rubber Shock Suspension (12U Space) Model: G-Shock-12L almost new with both front and back lid covers with it's own locking key as well... (REFER TO PHOTOS...) And the Moog Parametric Equalizer as a single unit because it didn't fit in the case unfortunately... But you get all 6 units shipped together as a complete set... NOTE: On the last picture the Bode Frequency Shifter, Bode Vocoder, and the second Moog Parametric EQ ARE NOT included in the bundle they are there just because that's where I had mounted both Parametric EQs but you only get one of the Parametric EQs and not 2 that are pictured there along with the other Bode stuff... Although the Bode Units are going for sale as well but are being sold separately so please refer to info description or ask questions if you're not sure. Thanks...

Here's what's included in the bundle:

- Moog 16 Channel Vocoder 327A - Model: MBVO - X 1 Unit
- Moog Custom Engineering String Filter - ( Fully Calibrated...) - X 1 Unit
- Moog Custom Engineering Dual VCO - ( Fully Calibrated As Well...) - X 1 Unit
- Moog 12 Stage Phaser - Model: MPKH - X 1 Unit

- Moog Ten Band Graphic Equalizer - Model: MKGE - X 1 Unit

Here's some info you may want to know about each unit:

* Moog Dual VCO - The Moog Dual Voltage Controlled Oscillator was built in very limited quantities by the Moog Custom Engineering Department A.K.A. Modusonic which has 2 Ultra-Stable VCOs based on the 3rd Revision of the Minimoog 921A VCO With Temp Comp UA 726 Matched Differential Pair Transistors. SUPER FREAKING PHAT..!!! Personally I think it beats any Minimoog I've own... The waveforms are just "EARGASMIC"... =) You've got to hear it for yourself... The Moog Dual VCO was designed to add that extra two oscillator fatness to other Moog Synthesizers as the Multimoog, Micromoog and the Minimoog at the time; although the Minimoog required the addition of the Keyboard CV Output Modification so it could control the Moog Dual VCO's pitch and route it's output back into the Minimoog's External Audio Input... The Micromoog & Multimoog did not require this mod because they have already a Keyboard CV Output Jack as well as their respective audio input. So basically you can use the Moog Dual VCO with any Analog Synthesizer with a Keyboard CV Output (1 Volt/Oct.) and an External Audio Input to pass the Dual VCO's output signal back in it and voila two extra fat Moog Oscillators in your set up.

* Functions, Features & Input/Output Option:

- Master Tune - Controls overall tuning of both oscillators or one when only used as single...
- Pulse Width - Controls width of both oscillator's pulse waveforms when used either as single or dual.
- Octave Select Multi-Switch Knob with: LO, 32', 16', 8', 4', 2'. (Both Oscillator 1 & 2 have their own Multi-Switch Knob)
- Waveform Select Switch with: Up Ramp/Sawtooth, Triangle, Pulse, Sine.
- Oscillator On/Off Switch - Each Oscillator has it's own on/off switch to quickly add or subtract one oscillator while performing.
- Oscillator 2 Sync Switch - Automatically syncs both oscillators together by the flick of a switch.
- Oscillator 2 Tune Knob - To tune or detune oscillator 2 from 1 either while synced or un-synced.
- Output Level Knob - Controls overall output volume.
- Power Switch - Turns on/off unit.
- Oscillator 1 CV Input Jack 1/4" (1 Volt/Oct.) - Controls oscillator 1 only.
- Both In 1 CV Input Jack 1/4" (1 Volt/Oct.) - Controls pitch of both oscillators while oscillator 1 being the master controller.
- Oscillator 1 Output Jack 1/4" - Outputs signal of oscillator 1 only.
- Oscillator 2 CV Input Jack 1/4" (1 Volt/Oct.) - Controls oscillator 2 only.
- Both In 2 CV Input Jack 1/4" (1 Volt/Oct.) - Controls pitch of both oscillators.
- Oscillator 2 Output Jack 1/4" - Outputs signal of oscillator 2 only.
- X 4 Multiple Output Jacks 1/4" - Note: These are not connected whatsoever to any circuit inside the unit, they only serve to split any input or output signal you wish to multiply.
- Runs on 120 VAC Only.

* Moog 16 Channel Vocoder - The Moog 16 Channel Vocoder was designed by Genius Engineer and Pioneer In Electronic Music Instruments Harald Bode in the mid 70's about and first released in about 1977 under the "Bode Sound Company" Brand which was manufactured by Polyfusion under the name of Bode Vocoder 16 Channel Model 7702, and was then licensed to the Moog Synthesizer Brand in about 1978 which was then released as The Moog 16-Channel Vocoder 327A Model MBVO. Both Vocoders are almost identical in circuit design except for a few slight variations in the type of components that were used in each but functions and features are basically the same...

* Functions, Features & Input/Output Option:

- Power Switch/LED: Turns the unit ON or OFF and LED Lights up When ON.
- Microphone/Line Switch: Switches between either Microphone Input or Line Input and it serves as the Modulator or what some may call the Trigger Input which can be either a voice through a Microphone or any Line In Instrument.
- Program Input Section: Input 1/4" Jack where you put your Microphone or Line Instrument, Level Knob which sets the amount of signal to pass through, Overload LED lights up when you are overloading or distorting the signal.
- Sample & Hold Switch/LED: Takes a sample of the of the signal and holds it and/or recall it when switched ON, LED indicates when it's ON.
- External Patch Switch/LED: Switches between either the Cross Patching coming from the Synthesizer Inputs in conjunction with the Analyzer Outputs or when switched OFF it goes in direct NORMAL Mode and send all the whole Signal & Frequency Range of whatever signal you fed into the Carrier whether be a Synthesizer or whatever.
- Analyzer Outputs: Analyzes the signal that's being fed into the Carrier and splits it's the Frequency Range as in the following set frequency outputs in Hertz - 50, 159, 200, 252, 317, 400, 504, 635, 800, 1008, 1270, 1600, 2016, 2504, 3200, 4032, 5080 Hz. - These are set frequencies that can be routed back into any of the Synthesizer Inputs for specific filtering effects with any of the desired frequencies from 50Hz to 5080 Hz. or above up to 15,000 Hz when Switched/Direct is "ON".
- Synthesizer Inputs: 50, 159, 200, 252, 317, 400, 504, 635, 800, 1008, 1270, 1600, 2016, 2504, 3200, 4032, 5080 Hz. - Receives any of the Analyzer Output Set Frequencies or any other Voltage Controlled Signal and filters it out at the input frequency you chose to put it into.
- Note: The resulting overall sound will depend on what type of signal you feed into the Carrier Input as it is what defines the Frequency Range at which the Analyzer Outputs can operate so if you feed a Narrow Frequency Range Signal into the Carrier then the Analyzer Outputs will only detect up to what that fed into the Carrier Input Signal's Frequency Range is set to...
- Carrier Input Section: 1/4" Input Jack receives Carrier Signal = Usually a Synthesizer, Level Knob adjusts the amount of signal you wish to let pass through, Overload LED indicates when overloading or distorting signal is going through the input.
- Switched/Direct Switch: Switches between the regular frequencies between 50 Hz to 5080 Hz or it can expand it above between 5080 Hz to 15,000 Hz - Used In Conjunction with External Patching as well.
- Hiss/Buzz Balance Knob: The Hiss & Buzz is the end result mix sound of the Program Input Signal vs the Carrier Input Signal and this knob is used in conjunction with the Hiss/Hiss & Buzz/ Buzz Mode Knob to color your output sound as well and balances the "Hiss" or or basically which are the HIGH Frequencies that come from the Program Signal Input which could be a voice from the Microphone input or any Line In Instruments and/or the "Buzz" which are basically the Lower Harmonics from whatever signal you put though. So if you have a very hissy voice through the microphone and wanna remove some of the popping annoying sound of it then you move the knob towards the Buzz or vice versa if that"s what you intent to achieve as effect.
- Hiss/Hiss & Buzz/ Buzz Mode Knob + LED's: Well this 3 position knob switch alternates between either just Hiss, Hiss & Buzz or Buzz alone. So if on Hiss only high frequencies will be heard or Buzz then the only the Lower harmonics will be heard, and if set on Hiss & Buzz then you would hear both but remember that is also used in conjunction with the Hiss/Buzz Balance Knob. LEDs indicate when the signal it's either on Hiss & Buzz.
- Vocoder Output Section: Status In/Out Switch lets you hear either the Vocoder Output Signal or just the Original Signal passing through the Carrier. LED Indicates if In or Out.
- Patch Select Jack: Switches Patch Select either Normal or External. NOTE: This is not a regular 1/4" Jack but a .206 Commercial Jack Type which is a little thinner than 1/4". To be used with the likes of the Moog 1121 Footswitch same used for the Minimoog Glide/Decay On/Off Remote Input Jack on the left of the keyboard.
- Sample & Hold Jack: Switches Sample & Hold On or Off. NOTE: This is not a regular 1/4" Jack but a .206 Commercial Jack Type which is a little thinner than 1/4". To be used with the likes of the Moog 1121 Footswitch same used for the Minimoog Glide/Decay On/Off Remote Input Jack on the left of the keyboard.
- Bypass Jack: Switches on or Off the effected signal in the Vocoder. NOTE: This is not a regular 1/4" Jack but a .206 Commercial Jack Type which is a little thinner than 1/4". To be used with the likes of the Moog 1121 Footswitch same used for the Minimoog Glide/Decay On/Off Remote Input Jack on the left of the keyboard.
- AC Line Selector + IEC Hub: Line Selector Switch selects either 115 or 230 AC Power. Receives 120/240 VAC at 50/60 Hz, 30 Watts Max.

* Moog 12 Stage Phaser - The Moog 12 Stage Phaser Model MKPH is one of the most complete and better sounding phasers ever created with proper phasing cycles without glitching or clicking between the end and beginning of next cycle like most cheap phasers out there. This unit can create some incredible Low End Sweep Effects with little effort and it's Amplitude it's insane so you have to be careful not to blow your speakers out if you go too wild with it on the low end... What makes this phaser stand out from any other phaser is it's texture richness, smooth cycle to cycle effect without glitching or clicking, wide frequency range sweeps, input/output control in a modular manner, crazy resonant stages with great depth texture, proper articulations & vowel like effects, smooth and harsh swirling analog phasing effects depending on settings and signal input, dual mono outputs 180 degrees out of phase from the other, infinite phasing type effects, internal & external control via CV, etc. Really the Moog 12 Stage Phaser is the only other Phaser that competes with the Bode Barberpole Phaser which there are only 3 around the world to my knowledge. I never found a Bode Barberpole Phaser but when I found the Moog Phaser I was happy with it so I got 3 of them so far and they all ROCK... =)

* Functions, Features & Input/Output Option:

- Phasing Stages Knob Switch: Selects between the Phasing Stages from 2, 4, 6, 8, 10, 12
- Resonant Stages: Selects the number of Stages used for Feedback Resonance.
- Chain/Mix Knob Switch: Selects between the Chain or Mix mode which works in conjunction with the Mix Resonance knob when in Chain goes straight directly through every Phasing Stage & Resonant Stage as you have it set and the Mix Resonance Knob sets the amount of effected signal fed back into the effect linearly, but when switched to "Mix" the Mix Resonance Knob controls the mix between the original Dry/Wet Signal.
- Rate Hz Knob: Controls the Sweep Speed/Rate of the Internal LFO Cycles.
- Amount Knob: Controls the Depth/Amplitude of the Modulation (size of range the effect sweeps..)
- Osc/Both/Ext. Switch Knob: Selects control of the sweep of either just the internal Oscillator, External CV Control or a combination of both External Control Voltage & Internal Oscillator.

- Motor Start On/Off: Turns LFO Motor On or Off.
- Status In/Out Switch + LED: In "In" position you can hear the signal being effected when "Out" you only hear the original signal. LED lit indicates the effect is in "In" position and the signal is being effected.
- Gain dB Knob: Helps to either boost the signal and/or add overdrive when setting it over the + signal above the zero or to diminish the signal when saturated by excessive amount of effect or fed with a very loud signal.
- Power On/Off Switch + LED: Turns unit On or Off, LED lit indicates unit is on.
- Foot Switch 1/4" Jack: Receives a 1/4" jack Foot Switch to turn the effect On or Off not the unit but the effect only.

- AC Line Selector + IEC Hub: Line Selector Switch selects either 115 or 230 AC Power. Receives 120/240 VAC at 50/60 Hz, 30 Watts Max.


* Moog String Filter - The Moog String Filter was the second rack mount unit after the Moog Dual VCO created by the Moog Custom Engineering Department A.K.A. Modusonic and by far is the RAREST of the whole collection of Moog Signal Processors as it was made in very limited quantities along with the Moog Dual VCO as they were made by special order to customers by the Moog Custom Engineering Department and not production pieces as the rest of the Moog Rack Mount Processing Units by Moog Music as Vocoder, Phaser, EQ's, etc. The Moog CE String Filter is a fixed 40 band filter array each one tuned to certain frequencies which can imitates pretty well most string instruments depending on what waveforms are fed into and the type of settings you put it at then you get different string instruments type sounds which are very convincing... They obviously work better with String Type Synthesizers as the Polymoog, ARP Pro Soloist, Freeman String Symphonizer, etc. which adds the true acoustic body resonances of a string instrument... In an early Keyboard Magazine from the 80's Deep Purple's keyboard player Jon Lord tells how he did a solo album with songs done with a Moog Polymoog passed through a Moog String Filter and then a Moog Music Rep heard the music and asked Jon Lord who had done the strings segment and the Moog Rep was blow out to find out that it was in fact a Moog Polymoog with the Moog String Filter that did the string section which sounded more like real string instruments.

* Functions, Features & Input/Output Option:

- Input Knob: Controls the amount of input signal in dB into the unit either in the minus for subtle volume control or in the plus for louder or to add overdrive/distortion to the input signal.
- Output Knob: Controls the amount of output signal in dB out of the unit either in the minus for subtle output volume control or in the plus for louder or to add overdrive/distortion to the output signal.
- Offset Knob: Adjusts the amount of the resonance from within the unit either in the minus or the plus settings.
- Ext CV In: External 1/4" Jack to control the Resonance via an External CV Source.
- Filter Frequency Selectors: These four determine which fixed filter band segments you chose to turn In/Out either Lo, Lo-Mid, Hi-Mid, Hi.
- Status In/Out Switch + LED: When switched "In" signal is being effected & when "Out" signal is not being effected. LED lit Indicates signal is being effected.
- Overload LED: Indicates the output is overloading.
- Power On/Off Switch + LED: Turns unit On or Off, LED lit indicates unit is On.
- Input 1/4" Jack: Where input signal goes.
- Output 1/4" Jack: Where output signal comes out.
- Runs on 120 VAC Only.

* Moog Three Band Parametric Equalizer - The Moog Three Band Parametric Equalizer is an underestimated sound processing unit as most people do not know how to use them properly or have used them unserviced and noisy so they do not get to appreciate the true nature of the unit as it was intended to sound. The Moog MKPE is a Fully Parametric Equalizer with a very complete and wide range coverage capable of controlling the three primary equalizing parameters which are Amplitude, Center Frequency & Bandwith ("Q"). which most Parametric EQ's within it's price range wont offer or perform as this one does. It is a great unit for Low End thickening and/or slicing out unwanted resonances at any desired frequency. When used in conjunction with the Drive and/or Gain dB reduction or increase you can create anything from either a more transparent/subtle type equalizing or either a more overdriven boosting effect and that's where most people fail to realize the wonders this unit can make specially when they have been professionally serviced electronically and mechanically like all my units so thy can perform as they should. They sound like heaven... =)

* Functions, Features & Input/Output Option:

- Low Section: 3 parameters are controlled in this section which are "Width Oct" or Bandwith ("Q") from .25 to 4 Octave Range, "Frequency Hz" or Center Frequency from 31 Hz to 4 KHz, "Height dB" or Amplitude from - 20 dB to + 20 dB.
- Mid Section: 3 parameters are controlled in this section which are "Width Oct" or Bandwith ("Q") from .25 to 4 Octave Range, "Frequency Hz" or Center Frequency from 62 Hz to 8 KHz "Height dB" or Amplitude from - 20 dB to + 20 dB.
- High Section: 3 parameters are controlled in this section which are "Width Oct" or Bandwith ("Q") from .25 to 4 Octave Range, "Frequency Hz" or Center Frequency from 125 Hz to 16 KHz "Height dB" or Amplitude from - 20 dB to + 20 dB.
- Drive Knob: Controls the internal operating level for Maximum Signal to Noise Ratio or to add Overdrive if desired to the input signal.
- Status In/Out Switch + LED: Turns On or Off the Equalizing Effect, LED lit indicates effect is On.
- Overload LED: Indicates when signal is distorted by overload.
- Gain Knob: Decreases or increases the Output Loudness Signal
