Pics of the inside below.

"The Moog Sonic Six is a 49 keys Duophonic Analog Synthesizer that features:

- Two VCOs with a balance pot between both oscillators, each oscillator has sawtooth, triangle, square/pulse waveforms (square wave pulse quality knobs for each oscillator), - 2 to + 2 octaves switches for both oscillator as well & besides being a 49 key duophonic synth, tone oscillator "B" can be tuned to concert tuning automatic by switch, pitch control inputs for modulation of oscillator by either LFOs or contour - Oscillator "B" Controlled By "A", can be high note priority, low note priority or both fully diatonic on duophonic mode... Pretty Neat Feature..!!!
- X 2 Multimode LFOs with 4 different waveforms per LFO, features a master balance pot for both LFOs & both come with switches to be used either individually contoured or mixed along with the master rate slider pot to create the most complex modulating effects... No other synth has this feature I think...
- Ring Mod Section with different modulating input sources either by mix of Oscillator "A" & "B", Oscillator "A" by External Source, Oscillator "B" by LFOs. Amazing textures can be obtained...
- Noise Source (White/Pink)
- Source Mixer Section with individual volume control pots for Oscillators A/B, Ring Mod, External Input & Noise Source...
- VCA Section with articulator switch to either engage or bypass, envelope type switches to either ADSR or ADR and pots to adjust the attack and decay... 3 individual trigger envelope inputs from either keyboard, LFO 1 or LFO 2.
- Direct Output Mixer Section for Oscillator A, B , Ringmodulator..)
- A True Low Pass Ladder (Butterworth) Type Filter with a wide frequency range specially after calibration upgrades done to it. Also with contour switch and modulation by LFO's switch + filter keyboard follow switch.
- Headphone Jack.
- Internal Speaker Switch.
- External Monitor Output Jack with Individual Switch as well.
- External input Jack & Pot to regulate the input amount.
- Accessory Socket 15 volt to use with any of the Moog Accessory Items like (Drum Controller, Ribbon Controller, Sample-Hold Controller, Etc.)
- External CV Inputs to control of Oscillators, Filter, Volume Control.
- Glissando
- Pitch Bender ( Upgraded..)
- Etc, Etc, Etc...

INFO ON THIS PARTICULAR UNIT AND WHAT'S BEEN DONE TO IT...

This Particular Moog Sonic Six is version 3 - Rev. "E"... So basically this is one of the later ones in production with many fixes and upgrades the previous versions & revisions didn't have... And well let's just say that everything in there has been worked on electronically, mechanically & electro-mechanically as well, here are the details on what's been done to it.

THE WORK DONE TO IT:
- The whole keyboard assembly has been meticulously worked part by part, the keys are brand new (all new & shinny), new bushings (lubricated as well), new gold platted buss bar, j-wires have been taken out one by one and polished/straightened & replaced, key holder caps cleaned, aligned the keyboard bed from all angles, etc, etc...
- Upgraded Pitch Bend Assembly Mod (Tight As Virgins...)
- All Electrolytic Capacitors Changed For High Grade Hand Picked Tested Ones.
- All Potentiometers Opened, Cleaned & Lubed Including Slider Pots & Switches. ( A Long Job Right There...)
- All Solder Joints Redone For Better Conductivity.
- All wiring harness through out the synths has been rearranged and organized properly for better aesthetics.
- All 1/4 Jacks Changed To New Ones.
- 6 Pin Cinch Jones Connector Changed As Well.
- All terminal connections cleaned, polished, reassembled & re-soldered properly to avoid noisy signal & weak connections.
- All precision resistor chain in keyboard tested and changed when needed.
- Precision resistors 1% tolerance added where needed for more stability in some sections in the circuit boards.
- Low leakage highly precise diodes where added where needed including better diodes for the power supply.
- Many other upgrades where made inside the circuit boards all done according to the last revision of the Original Moog Service Manual + Addendum Sheets and let me tell you no other Sonic Six has ever sounded as sweet musically, full in character and stable as this one...
- Unit has been properly calibrated & tuned to factory specifications so this synth is working A1.

This synth has a rich thick Butterworth Low Pass Ladder Type Filter that everybody raves about & it's why people love the sound of this synth... It's A Beast..!!!"
