Great Vintage Combo Organ from the early 70s, in fantastic shape and everything works.
It's even got a built in ribbon controller and fuzz!
Includes tilting chrome stand and volume pedal.

If you aren't yet hip to this classic 'board, here's some info from combo-organ.com

Top-of the line single-manual. 44 Treble Keys, 17 Bass keys, switchable to extend the Treble section. Adds a few new voices (Marimba, Fuzz , Attack and Sustain) over the YC-20, and a couple of really unique features:

Portamento or "pitch ribbon" - used to make theremin-like sounds (not a "pitch-bender", as you might expect). It has it's own 16', 8' and 4' flute voices. The range of the pitch ribbon is 3 octaves. This strip is NOT physically the same as the one on the YC-45D - they're not interchangeable.
Presets - two sets of miniature-tone levers that duplicate the function of the regular Ch I and II levers. They can be preset and selected at the touch of a switch, similar to Hammond presets, but they can be adjusted right from the top of the organ. I think these are quite similar to the preset bank found in the CS-80 synthesizer.
I had the opportunity to play one of these recently, and so have more details. 

The Attack 2-2/3' adds a percussion-like attack (but different from the Percussion sound). The range of effectiveness is very odd, though - with the Attack 2-2/3' Extension off, it works on all keys down to the C# in the first white octave. The Extension tab "extends" this range down to the F# in the black octave - very strange.
The 8' voices have a couple of odd features. The Sustain 8' tab adds a sustain after key-release to the 8' voices only (Section I or II). The normal Section I voices for all footages except 8' give a classic combo organ style "key click", just like on the YC-20. The Attack 8' tab adds a percussive attack to the 8' voice, but it's still not the same as the regular key-click - not as sharp. Why they chose to limit this to the 8' voices I have no idea.
The Fuzz does not affect the Manual Bass voices
The Marimba adds a repeat sound as you hold a key - it alternately plays the key pressed and the octave or octave+5th, depending on the Mar. Select setting. The Mar. Speed selects slow or fast repeat.
Portamento strip. Controls only the three Portamento voices - no other levers have any effect on the Portamento sound. It has the same key-click found on the Section I voices. It's a single-triggering click - holding a spot on the strip and pressing another does not regenerate the click. The strip is monophonic. You press on it and it plays a note, then you can slide your finger up and down the strip, and the pitch goes up and down continuously, like a trombone. If you press on two different spots, only the last one pressed will sound. This allows for some interesting effects - if you hold one spot and repeatedly press another, the pitch jumps back and forth between the two, whether the second spot is higher or lower.
The main Volume control controls the overall volume, including the bass section, and there's no separate volume for the Treble section. What this means is that you don't have full control over the Treble/Bass balance - you can get the bass section only so loud relative to the treble, and no louder

Yamaha

Known for excellent instruments of all types, Yamaha's combo organs are arguably some of the best ever made. The first, the A-3, was introduced in 1966, then the YC's started in 1969, and were available throughout most of the 1970's. They are capable of cheesy combo organ sounds as good as any, but plug one into a Leslie, adjust the "levers" appropriately, and you have a pretty decent Hammond substitute. The Yamahas use levers instead of drawbars to add voices and effects in varying amounts. They also offer a really good percussion - quite like a Hammond, an excellent vibrato, and a sizeable assortment of other features, some quite unusual, some actually useful. The YC's are the only combo organs I know of that make extensive use of IC's. The  frequency dividers consist of a few IC's and a handful of discrete components, unlike the dozens or hundreds of transistors, resistors and capacitors found in most combo organs.  The older oscillators were discrete components, but there were two newer versions that used one or two IC's per oscillator.

Date info presented here comes from the Yamaha Manual Library. Price info is from a 1977 retail sales flyer (not a Yamaha price sheet).  A chronology of Yamaha instruments, including the YC-series is available here.

Colors:  As far as I know the A-3 came only in red and ivory.  The YC-line came in various colors, and I think some were only produced for a limited time.  Here's all the information I have on the colors, based on the sales flyers and service manuals I've seen:

A-3

The A-3 was the first Combo organ made by Yamaha. Introduced in 1966, it appears to be the forerunner of the YC series. I've only confirmed the existence of three of these, and originally wondered if it was even a production model. Well, it's listed on Yamaha's manual library, and there's a service manual available for it, so it's for real, but probably was not very widely sold. Details on the levers were provided to me recently by the owner of one, who also provided this description: "A little like a YC-20 with no bass. It can get raucous or Hammond-like. Not as much like a Continental as the YC organs, no bright lever"

Controls:
   Knobs: Pitch, Volume
   Levers: Tone, Vibrato, Vibrato Speed, Flute 16', Bass 16', Flute 8', Clarinet 8', Brass 8', Reed 8', String 8', Flute 4', String 4', Flute 2-2/3', Flute 2', Flute 1-3/5'

The Tone lever affects the sound in a way similar to the Contour knob on a Vox Jaguar. The non-Flute voices mix in some additional harmonics from the higher ranks, and then are filtered differently than the Flutes, similar to the red, yellow and green voice levers on the upper YC models (30, 25D, 45D).

Thanks to Kirk for the following pics:

And thanks to Timothy E. Henley, for these nice ones of a slightly different A3.  Note the wood bottom section.  Tim tells me this is real wood, not laminate.  Note the neat anvil-style case, and how the organ actually goes in it upside down.  Also note how the volume pedal plugs in (using a very odd plug), rather then being hard-wired like the YC's.  And dig the AC accessory outlet - when was the last time you saw one of THOSE on a piece of gear?

YC-10

The "entry level" YC model. 32 Treble keys, 17 Bass keys which can be switched to extend the Treble section.

Controls:

  • Knobs: Pitch, Volume
  • Levers
       Vibrato: Vibrato
       Bass: 16', Manual Bass
       Section I: 16', 8', 4'
        Balance
        Section II: Bright, 16', 8', 4'

Contrary to my earlier assumption, and according to the YC-10 owners manual, the Manual Bass lever switches the bass section in and out (either Bass sound or an extension of the treble section).  I had previously thought it was a "Balance" lever, but either I was mistaken, or there was more than one version of the YC-10.  The "I" and "II" sections are different, probably the same sounds as the YC-20.  The manual describes the "I" section as "the basic sound of the Combo Organ", which, if it's wired like the YC-20, is true, in that it controls the full, unfiltered output from the oscillators and dividers.  The "II" section is heavily filtered to produce the flute tones and bright tones.

The top on the YC-10 was a leatherette finish, not the high-gloss polyester found on the YC-20 and 25D.  

Date introduced: 1969. In 1977, the YC-10 list price was $595.

And here's a cool circular "owners manual".  It looks like you turn it around to help figure out different features":


YC-20

The YC-20 has most of the basic features you'd need in a Combo Organ. In addition to the features of the more spartan YC-10, it offers more voices, percussion, and Touch Vibrato in addition to normal vibrato. I owned one of these until recently, so I'm quite familiar with it.

This organ is incredibly well-made. Mine survived a UPS trip from Ontario to Georgia in a cardboard box with NO padding, and arrived virtually intact. The top (where the controls are mounted) and keybed are both hinged, and lift up for complete easy access.

There are 44 Treble keys and 17 Bass keys. The Bass section can be switched to extend the Treble section, for a total of 61 keys. The I and II voice sections have different sounds and are not simply two instances of the same circuitry. The I section has a brighter, fuzzier tone, more like a Vox, and the II section, with the Bright lever off, produces flute tones - very much like Hammond tone wheels. The Bright lever works only with the II section, and makes it even brighter and fuzzier than the I section, sounding more like a Farfisa. By adjusting the Bright and Balance levers, you can achieve quite a variety of great Combo Organ sounds. The Percussion is very similar to Hammond-style percussion. With the II section on, Bright lever off, and Percussion on, you can produce a very acceptable Hammond sound. Played through a Leslie, the effect is excellent. If you turn the Percussion all the way up, and add just a hint of 16' and 8' levers, you can play the organ break in "Green-Eyed Lady" and it sounds better than some Korg/Roland type organs I've tried (Seems like the VK-7 sounded pitiful when I tried this). Touch vibrato is a pretty nice feature. When activated, moving the keys side-to-side causes the pitch to waver up and down - very expressive. The Bass section has it's own dedicated 16' and 8' levers, with separate volume. The lowest notes played with the 16' lever can go REALLY low. There's no provision for adding bass pedals. The Pitch knob only makes slight changes - from about -1% to +2%.

The top is made of wood, with a high-gloss polyester finish.

The YC-20 uses the same legs as the YC-25D - they're interchangeable.

Date introduced: 1970. In 1977, the YC-20 list price was $895. Weight 88 lbs.

The YC-20 is also know as a "Tupe Piano" (It's an inside joke - email me for details)

Sounds: Here are a few sample sounds from the YC-20.  Bear in mind that I'm not a very good keyboard player, so please ignore my lame attempts at reproducing some well-known phrases from popular 60's tunes and concentrate on the sound of the organ instead.  I don't remember the exact registrations I used on these, but I've indicated the main features in play:

'96 Tears':  Section II voices with Bright lever on full
'Double Shot': Same as 96 Tears
'In-A-Gadda-Da-Vida': Section I voices
'Cherokee Nation': Section II, no Bright, plus Percussion
'House of the Rising Sun': Section I voices
'Green-Eyed Lady': Percussion on full, plus a very small amount of Section II voices.

And here's the circular "Owners guide" for the YC-10:


YC-30

Top-of the line single-manual. 44 Treble Keys, 17 Bass keys, switchable to extend the Treble section. Adds a few new voices (Marimba, Fuzz , Attack and Sustain) over the YC-20, and a couple of really unique features:

  • Portamento or "pitch ribbon" - used to make theremin-like sounds (not a "pitch-bender", as you might expect).  It has it's own 16', 8' and 4' flute voices.  The range of the pitch ribbon is 3 octaves.  This strip is NOT physically the same as the one on the YC-45D - they're not interchangeable.
  • Presets - two sets of miniature-tone levers that duplicate the function of the regular Ch I and II levers. They can be preset and selected at the touch of a switch, similar to Hammond presets, but they can be adjusted right from the top of the organ. I think these are quite similar to the preset bank found in the CS-80 synthesizer.

I had the opportunity to play one of these recently, and so have more details.  

  • The Attack 2-2/3' adds a percussion-like attack (but different from the Percussion sound).  The range of effectiveness is very odd, though - with the Attack 2-2/3' Extension off, it works on all keys down to the C# in the first white octave.  The Extension tab "extends" this range down to the F# in the black octave - very strange.
  • The 8' voices have a couple of odd features.  The Sustain 8' tab adds a sustain after key-release to the 8' voices only (Section I or II).  The normal Section I voices for all footages except 8' give a classic combo organ style "key click", just like on the YC-20.  The Attack 8' tab adds a percussive attack to the 8' voice, but it's still not the same as the regular key-click - not as sharp.  Why they chose to limit this to the 8' voices I have no idea.
  • The Fuzz does not affect the Manual Bass voices
  • The Marimba adds a repeat sound as you hold a key - it alternately plays the key pressed and the octave or octave+5th, depending on the Mar. Select setting.  The Mar. Speed selects slow or fast repeat.
  • Portamento strip.  Controls only the three Portamento voices - no other levers have any effect on the Portamento sound.  It has the same key-click found on the Section I voices.  It's a single-triggering click - holding a spot on the strip and pressing another does not regenerate the click.  The strip is monophonic.  You press on it and it plays a note, then you can slide your finger up and down the strip, and the pitch goes up and down continuously, like a trombone.  If you press on two different spots, only the last one pressed will sound.  This allows for some interesting effects - if you hold one spot and repeatedly press another, the pitch jumps back and forth between the two, whether the second spot is higher or lower.
  • The main Volume control controls the overall volume, including the bass section, and there's no separate volume for the Treble section.  What this means is that you don't have full control over the Treble/Bass balance - you can get the bass section only so loud relative to the treble, and no louder

Here's a technique for using the Fuzz, submitted by fellow YC enthusiast, Danny:

"I don't know if you're into 'fuzz' as much as I am, but here's a useful trick: As you know, with high lever settings the fuzz just saturates very quickly, and intervals other than octaves and fifths get out of hand.  If you try setting your main, beefy sound on the "I" voices, and then have a lighter amount of middle/upper-mid levers open on the right, you can then use the balance and brightness controls to "gain stage" the fuzz circuit. That is, by favoring the quieter "II" voices, you drive the fuzz less, and can play way more complex chords intelligibly, or move towards the "I" voices for more grind."

The stand allows the organ to be rotated 110 degrees, from nearly vertical to about 30 degrees downward. The YC-45D uses the same stand.

Date introduced: 1970

I don't have a very good picture of a Red one, but you can see one by clicking here  

Here are some pretty good pics of the controls.  I pieced them together so they're in roughly the right orientation:


YC-25D

The YC-25D is basically a dual-manual version of theYC-20 with several added features. I currently own one of these, so I'm quite familiar with it as well. The upper keyboard has 49 keys, and the lower manual has 30 Treble keys and 19(!?!) Bass keys which can be switched to extend the Treble section. Instead of having a Ch I and Ch II set of levers, one set is exclusively for each manual. Unlike the YC-20, both the upper and lower levers produce the same flute-like tone as the II section on the YC-20  However, the lower manual has a nice key-click, similar to the one found on the YC-20/YC-30 section I voices. The upper manual has all the same footages as the I section on the YC-20, and the lower manual has the same footages as the II section, plus a 2-2/3' lever. Both sections have the bright lever as well. Since the cheesier sounds of the YC-20's I section are gone, the upper manual of the YC-25D has four additional voices: Trombone 16', Kinura 16', Trumpet 8', and String 4'. These provide a nice selection of fuzzy, gritty, cheesy combo organ sounds. The Percussion section has been enhanced, with separately adjustable 4' and 2-2/3' levers, comparable to 2nd and 3rd harmonic percussion on a Hammond. There's also a Length lever for the percussion, which increases the time it takes for the percussion sound to die down. Similar to the Short/Long switch on a Hammond, but continuously variable. Percussion as well as Touch Vibrato are available on the upper manual only. The upper manual has a couple of additional features. There are two tabs to the left that select Touch Mute and Attack Glide. Touch Mute reduces the volume and mellows the timbre, but moving the keys side-to-side causes the timber to waver, giving sort of a "wah-wah" effect. Attack Glide is similar to Farfisa's Syntheslalom. When you press a key, it quickly "glides" up to the desired note. Not a very useful or pleasing sound, in my opinion, but fun to play with, nonetheless. There's also a lever to the left of the upper manual that controls the volume balance between the two manuals. The lower manual is basically the same as the YC-20 with the II section only, except it has the additional 2-2/3' lever. The Bass section is monophonic (when using the Bass voices - polyphonic when playing the treble voices), but adds a couple of extra features. Bass Guitar gives a plucked string-like sound that decays even if you hold the key. The other feature appears to vary on different models. Some have a "Sustain" lever, that adds a sustain after key release. This is the feature specified in the 1974 and '76 sales brochures that the picture below comes from. But on mine, the lever is labeled "Pizzicato", and it adds a sustain more like the Bass Guitar - it fades out even if you hold the key, and the sound stops immediately upon key release. The Sustain and Pizzicato features both affect only the regular 16' and 8' bass voices - the Bass Guitar is separate. The YC-25D can also be fitted with bass pedals, and the knob that switches between Manual Bass and Pedals effectively replaces the "Man Bass" switch on the YC-20 - switching the knob to the "Pedals" position, even if no pedals are connected, extends the bass section to play along with the rest of the lower manual. The YC-25D uses the same legs as the YC-20.

YC-45D

The "Cadillac" version. Has most of the features of both the YC-30, and the YC-25D, plus the following additional features: Upper Manual - 5-1/3', Kinura 8', Piano, Harpsichord, Vibraphone, Sustain 8', 4', Marimba, Piano, Harpsichord, Attack Mute, Percussion 16', 4', 2', 1. Bass - Tromba. Pitch ribbon: Slide Trombone, Squawk, Birds, Astro. The upper keyboard has 61keys, and the lower manual has 42 Treble keys and 19(!?!) Bass keys which can be switched to extend the Treble section.

Note that in addition to the fact that the pitch ribbon is NOT the same as the portamento strip n the YC-30, it's function is also different.  Rather than the plain flute voices, it controls the Slide Trombone, Squawk, Birds and Astro voices.  Slide Trombone and Squawk are bright organ-like voices, Birds sounds like chirping, and Astro is sort of a ring-modulator effect.  The range of the pitch ribbon is 3 octaves.

The YC-45D uses the same tiltable stand as the YC-30.

Date introduced: 1972. In 1977, the YC-45D list price was $2,975.

Weighs in at a hefty 132lbs!

-For sale is this original white transistorized Yamaha YC-30 combo organ, with legs (on the image, the instrument is not mounted on its legs; stand on picture not included). The YC-30 is the top of the line of the single-manual organs of the YC series.

-This organ can produce the round compressed sound of a Vox Continental, the raunchy gritty aggressive reedy sound of a Farfisa, and, to some degree, the richer more complex overtones a Hammond. The YCs are know to cover a wide range of organ sounds, which makes them so desirable.

-While having all the great basic features of all organs of the YC Series (the Yamaha-type drawbar system, vibrato, separate bass keys, etc…), the YC-30 boasts unique and super cool characteristics: a touch ribbon (which produces a sound which immediately evokes the theremin; magical with delay and reverb), fun marimba options (repetitive percussive Zappa-esque electronic claves: also great with or without effects), the famous YC touch vibrato (swinging the keys left and right produces vibrato), two miniature panels to « record » « presets », possibility to modify attack, percussion and sustain on some footages, and the absolutely fantastic FUZZ effect… (see video)

-YC Series organs are extremely well conceived and solidly built. Compared to combos of the time, their built quality was way above average. The Japanese ingeneers thought of encapsulating some components to prevent the dust from entering: this way, no crackling, no noise, nothing else than the pure sound.

--This instrument is in overall good condition. Everything works. The touch ribbon sometimes acts up, but I feel it’s just a contact thing. As with all older instruments, getting this unique organ serviced and eventually recapped would rejuvenate it and give it many more years of life… but everything works on it. Cosmetically, this instrument is in surprisingly good condition, though shows normal little signs of aging. Tabs missing on Portamento section; some tabs are cracked, but functional. The inside is very clean, shiny and dustless.

- Ideally, this should be a local pickup: this is quite heavy to be shipped. I can deliver if you're not too far from Montréal. Inhabitants of Québec City / Sherbrooke / Ottawa / Mont Tremblant / Drummondville / Saint-Hyacinthe, etc.: we can meet halfway. American friends, I can meet you at the borders (Quebec side). Thanks.

Yamaha: "Combo Organs that Strove to be More Expressive Five years before introducing the SY-1, we released the YC series of combo organs for band musicians. In contrast to our Electones, which featured upper, lower, and foot keyboards that allowed a single player to perform as an entire ensemble, combo organs such as the single-keyboard YC-10 attracted considerable attention as a new type of highly portable instrument. In terms of both concept and technology, the combo organs of the YC Series have had a major effect on the development of modern synthesizers. The sixties saw the kind of music played by bands such as The Beatles and The Rolling Stones become extremely popular all over the world, producing a shift in demand from organs installed permanently in churches and public facilities to highly portable organs for stage use. With its single 49-key keyboard, four color variations, and a compact design that fit neatly inside a hard, suitcase-type cover, the YC-10 was truly a next-generation organ. It also differed markedly from the Electone in that its sound was output via a separately sold guitar or bass amplifier.A later addition to the YC lineup, the dual-keyboard YC-45D was capable of changing sounds instantaneously—functionality achieved through the addition of a large number of tone levers, as well as preset levers. Adopting a similar approach to the subsequent CS-80, these components offered a glimpse into the future of the synthesizer.The YC-45D was packed with many other novel functions that narrowed the gap with the latest synthesizers—for example, keys could be wiggled left and right to produce a touch vibrato effect, while a ribbon controller provided for smooth pitch bending. Looking back, one cannot but admire how far the developers pushed the expressivity of the keyboard instrument.Although no further additions were made to the YC Series after the YC-45D, the desire to make keyboard instruments highly expressive—which lay at the heart of their development—carried over into the SY-1 and subsequent Yamaha synthesizers."
