Moog Source

“Amazing beast of a bass / lead synth.. this Moog Source not only attracts any eye but delivers the goods in the sound dept. The Sound is very much like an original Minimoog with two OSCs. It slays any modern moog wannabe and even the modern moog synths.. It just sounds “right”.

Best news is that it is fully functional. The Increment Wheel is working perfectly as well.. In all, everything.. all jacks, keys, buttons work great. It tracks great.. pitch is steady and right.

If you are looking for a Moog Source.. this one is ready to serve any studio or stage rig. ” Click here to visit listing on eBay

Korg Polysix

“The Korg Polysix is an all-time classic, highly-sought after analog synthesizer. This unit is clean and in great condition, with no broken or missing keys or buttons. It does power on – however, it suffers from the same problem that nearly every Polysix was affected by, which is that the battery on the KLM-367A board leaked and damaged nearby traces and components. This synthesizer did function when I first acquired it in the early 2000s. However, at some point the battery issue did cause it to cease working properly.

Repair was attempted on this synth: The leaky battery was removed and a new battery as well as IC chip and socket were installed. However, that didn’t solve the problem. Someone knowledgable about this issue should be able to repair this keyboard, or install a new KLM-367A board and have themselves a wonderful vintage analog synth.”

Korg DW-8000

“Vintage Korg DW 8000 Programable Digital Waveform Synthesizer (mid 1980’s) with manual and hard case with wheels. If you’re looking at this you probably already know it’s a classic.

I can also send you a folder of sound banks including the factory banks and other user banks I’ve collected which can be loaded via midi using a free SysEx program available online for Mac or PC (I’ll send you download links).

This synth works/sounds great and does everything it’s supposed to. There are some light scratches in as seen in the photos but they don’t affect usability or visibility.

I’m selling because I rarely use it and am pairing down to move across the country. ” Click here to visit listing on eBay

Korg Lambda ES-50

“HAVE YOU ALWAYS WANTED TO BUY A LAMBDA WITH PEACE OF MIND? WELL, THIS IS YOUR CHANCE TO MAKE THAT A REALITY!!! 😉

This MUSICIAN’S DREAM-GEAR is FULLY FUNCTIONAL, and I would say it is in EXCELLENT condition, especially for its age! However, and respectfully, since everyone has different standards, please don’t take my word for it; I’ll let the pictures do the talking. 🙂

I am sure that if you are looking at this item, you know everything about it. So, I will first tell you about this particular gem:

IT HAS JUST BEEN FULLY SERVICED!
The following services were just done, which cost me over $1500! IF you find another one for less than what mine is selling for, and since most of the used ones out there, that are supposed to be “fully functional”, turn out NOT to be; you will then need to find someone who would work on these (which is very rare nowadays), and then who knows how much it would cost to make it fully functional??! Especially since these synths are over 42 years old, which means unless they had just been serviced, hardly any of them would be fully functional; and CONDITION IS EVERYTHING!

SERVICES DONE:

Full inspection
Key-bed fully serviced
ALL Sliders serviced
ALL buttons serviced
ALL contacts cleaned
Cleaned inside and out
REPLACED ALL THREE TOGs!
REPLACED ALL 48 ensemble CAPS!
REPLACED ALL 96 percussive CAPS!
REBUILT ALL 9 DIVIDER MODULES!
REPLACED ALL other main board CAPS!
OVERHAULED THE SOUND/VOICE BOARD

From start to finish, it took over TWO MONTHS to complete the above service! Partially because of the complex built, but also sourcing the parts was not an easy task, and required international outreach!” Click here to visit listing on eBay

Korg Poly-61

“For sale: a fully functional, Korg Poly-61. All the keys work, as do the buttons on the front panel, LEDs, Joystick (pitch-bend, DCO & VCF modulation levers), dials and switches.

All the rear inputs have been tested: Line-out, Headphones, Sustain, Arpeggiator trigger, Prog-up trigger. Tape input and output works correctly (see later photos).

Oscillator board is fully functional for all 6 oscillators. Patch storage works, all the original sounds have been re-entered and can be fully edited, as they were copied from the supplied manual. A link to the .wav file containing the patches will be published on my Blog on completion of the sale and you’ll get a link to them.

Like most (if not all units), this Korg Poly-61’s digital board had suffered from battery corrosion after around 2 decades of non-use, before being restored. The faulty, corroded components were removed and replaced with their equivalents (in the case of the ICs, capacitors and resistors) or compatible components (in the case of the transistors). The new ICs were socketed. Both corroded signals were replaced with patch wires. To avoid replacement battery corrosion a battery pack with easily removable NiMH rechargeable AA batteries was added and securely fitted, flush with the underside of the synthesiser. I’ve been able to test that the internal RAM is retained for at least a month of non-use. The cables to the digital control PCB can be easily be disconnected via the cable for future servicing.

The keyboard itself is in good condition, given its age. There are minor scuffs to the veneer at both ends (marked in yellow on the photos). The power cable is clean and undamaged as is the plug – even the original cable tie still holds the cable in place!

If you don’t know what a Korg Poly-61 is, it’s a dual, digitally controlled oscillator synthesiser from Korg, the first synth on their transition to digital technology. It stores 64 battery-backed patches; has a resonant filter and a classic ADSR envelope. It was renown for its gutsy sounds thanks to the sub-oscillator, which can also create chorus-style effects and is now highly collectable. However, I have to sell it as I need the space!” Click here to visit listing on eBay

Moog Prodigy

“I have absolutely LOVED this instrument and am sorry to see it go but need to free up some space.

It comes with the original user manual. Has sockets on the rear to connect with a sequencer (CV and Gate) but needs an S trigger converter. This I have included along with the special plug required to connect to the S Trigger input socket.

To use MIDI there is a switch on the rear and when this is ‘on’ the synth will respond to MIDI. The Moog keyboard and pitch/modulation wheels are then disabled. It is a fairly basic implementation but the synth does respond to pitch bend and modulation as well as pitch when played from another midi keyboard. MIDI in is pre-set to channel 2.

It has a wonderful sound (as only a Moog can sound) and setting up a patch is really easy as there are relatively few knobs to tweak. I have included the pages from the manual which outline the specs in more detail.

This is a vintage instrument and I do not have the original box. I am therefore NOT willing to entrust this to either Post Office or Courier. Please do not ask. Regret this is for collection only.”

Sequential Circuits Prophet 5

“This is an early Prophet 5 with model listed as 1000 and serial number 1593 . (Rev 3) It’s a synth that I’ve had for many years but when taken out of storage was working intermittently and eventually stopped producing any sounds.

The Prophet was brought into a reputable shop in Long Island and diagnosed. After replacing power supply and trouble shooting I was given the following tech info.

5- 2.2 wf @ 50 vdc

2- 10 wf @ 50 vdc

1- 2200 wf @50.vdc

Not being a technical person I don’t know the meaning of this information but on advise told that the instrument can be repaired by the right person and given the high price that a fully working prophet will sell for is worthwhile for the right tech person. It is my understanding that the #4 board is the actual problem and if replaced should get the unit working. The outer physical condition of the Prophet is clean and cosmetically excellent. I’m including a number of photos.

I’ve decided to put the instrument on auction and sell to the highest bidder at a no reserve, and low starting bid. Presently the synth is in Montauk NY and could be picked up directly here, or could meet the buyer in Rockland county NY for a local pickup. Shipping is also possible and will charge actual shipping cost (USPS)

I forgot to mention that this vintage of Prophet 5 in full working order has been selling from five thousand to eight thousand dollars. Well worth it to get it up and running if you have the ability to do it. Good luck on the bidding. thanks

I would like to add the following Clarification. THe synthesier is powering on but not in working order. My original descrption clearly states this. The person that did the rebuild on the power supply and did the trouble shooting , indicated that it could be repaired but would need work by someone with the ability to repair it, It is not in working condition now and was indicated in the original description. I had originally checked off “Used” in the the eBay app and I’m told that this is not considered used but now sure why that is the case. In any event this is a unit that is not working, needs repair and I am selling it as is with no question as to whether the synthesizier is working or not. Also, indicated was that it might be better to shiop Via UPS, THe eBay app gives options on shipping and USPS was clearly the better choice. I’m flexible on the mode of shipping, and will of course agree to whatever is the most cost effective mode. THanks. Joe” Click here to visit listing on eBay

Korg Poly-800

“Fantastic repair project for someone with the electronics know how. This is a Korg Poly 800, one of the first affordable analogue poly synths with MIDI ever brought to market. This one does not power up, but the keybed/keyframe is intact, Joystick etc, all could be sold for parts.

Suspect it may be either a power supply issue (battery contacts are corroded) or main board, but don’t know for sure. Hence the very low asking price At a time when Roland was doing well with their Juno-series, KORG countered with a poly-synth of their own in 1983 with the Poly-800.

The Poly-800 was comparable to the Juno-106, at the time, with respect to the fact that musicians now had access to affordable programmable polyphonic analogue synthesizers (it listed for under $1,000) with memory storage, stable DCOs (digitally controlled oscillators) and a new state-of-the-art technology called MIDI

The Poly-800 is an eight-voice instrument (two more than the Juno series) with 64 memory patches (half of what the Juno-106 offered) and up to 50 editable parameters! Like the Juno, the Poly-800 had one DCO per voice, although it did feature a Double mode in which the oscillators could be stacked up for a fuller sound and only four voices of polyphony.

The analogue filter is a 24dB/oct low-pass which is shared by all voices (the Juno has separate filter chips for each voice). There’s also a stereo chorus effect, chord memory, a simple built-in sequencer, three digital envelope generators (for the oscillators, the noise generator and the filter), and a funky joystick used to adjust the pitch, modulation and the filter. Unlike the Juno, which was still a “studio” instrument, the Poly-800 was built for the performer.

With a light-weight plastic case (only 10 lb.), a couple low-profile sliders/knobs and only 49 keys, the Poly-800 can run on batteries and has guitar strap pegs so it can be worn like a keytar. A less common reversed colour keys model was released for a unique look as well. All sound editing is accomplished by scrolling to a given parameter, described by little more than a two-digit number, and pushing the up or down buttons to adjust it.”

Yamaha SY85

” Up for sale is this Classic Yamaha SY85 synth.

These are fantastic synthesisers and was ground breaking for its time.

This has been a very tough decision to decide to part with this unit (and I may end up changing my mind), but the truth is, I have some new projects on the horizon and this is unlikely to get the attention it deserves so I need to move it on.

If you are reading this then you will almost certainly know about this unit and how good it is. Loads of articles online about it’s function and features so these won’t be repeated here. Has 2 extra RAM SIMMS installed ready for loading samples into (will try to get a photo shortly). Lots of support for this online and undoubtedly software available to use with/alongside it.

The aging floppy drive has been replaced with a modern USB solution, so you can download various songs, instruments, samples etc and load them without worrying about the floppy drive wearing out. It even has a screen on it so you can scroll through to select the right ‘disc’/sample to load. This makes searching for and trialling new sounds so much easier as you can download them onto any usb stick and go straight from there. Please note however, that no usb is supplied but these are available pretty much anywhere. If you want to have the old (probably non-functioning) floppy drive for this, it is available at extra cost. Please let me know after purchase.

In terms of condition, the unit has been well looked after but does have some surface marks and wear, but remember that this model is from 1992, so you have to expect something. The sliders are very smooth in use and all the buttons/lights etc work. There is a slight crack to the plastic on slider 8 however this doesn’t prevent it’s operation, it’s merely cosmetic. You can see this in one of the pictures.” Click here to visit listing on eBay

Roland Juno 106

“Juno 106.

This is working and still produces the wonderful sounds it is famous for.

It probably needs an overhaul. There are 4 keys that are not working; I have marked this in red on one of the pictures. Of course, if you play it via a midi connected keyboard, it plays perfectly.

Some of the menu buttons seem slightly iffy. I just tested it (after a prolonged period of non-use) and for example, some of the blue bank buttons didn’t work but soon started to after a bit of repeated use.

I dare say that an overhaul by someone who knows what they are doing might work wonders.

Also, one of the sliders is missing the plastic knob part although the slider still works perfectly. It is the “sub” slider and you can see it in the main picture.

Please note, this is local collection only due to size and weight. I could potentially deliver it depending on your location so please feel free to enquire.

Item sold as is – no returns.” Click here to visit listing on eBay

Roland SH-1000

“I’ve worked on this synth myself and it’s completely at peak performance. It’s date stamped 1973 inside, which was the first year of its production, and it’s Roland’s first synthesizer, so it’s a piece of history!

When I got it, it was fully working but a few months later the divider chip failed. I replaced it with a New Old Stock chip I sourced from Japan, and I installed it with a plug receptacle, so if you ever need to access it again you can simply unplug and plug it, rather than de-solder/re-solder it. I don’t think you’ll ever need to mess with it again because it was replaced with an unused NOS chip, so I suspect it will last another 50 years or more. While I was going through it I cleaned all of the key contacts, which cleaned up a few notes that were double firing. It now works perfectly, as new.

I don’t think you’ll find a better example of this synth. It’s super vibe-y and the filter is magic. It has an early Low-Pass filter design, called a diode filter. These were only used for a year or two in the early 1970’s and they were replaced with cleaner designs, but there is something very special about the sound. When you push the resonance high you can hear the gnarly, gritty diode sound. And it’s more noticeable when the cutoff is higher, too. It’s much subtler when you have the resonance at more reasonable levels, or when you have the filter controlled by the ADSR envelope because the ADSR only pushes the cutoff up momentarily. Watch the first DEMO video (link above) on YouTube to hear it firsthand as I go through it.

It’s 37 keys, but there’s a L-M-H octave switch to add an octave on the top and bottom. It is a monophonic synth, so it’s meant for leads and basslines. It is killer for both!!”

Georges Jenny Ondioline

“For sale is an incredibly rare vintage Georges Jenny Ondioline monophonic analog tube synthesizer keyboard. This model is believed to be from the 1950s and a unique transitional model due to cabinet design using real hardwood. This one has been completely restored with no attention to detail spared. Work included restoring and rebuilding the amplifier circuitry, keyboard, switches, and refinishing the wood cabinetry, with utmost attention to accuracy and playability. As expected for a vintage instrument of this age, there are still some signs of aging. This is likely to be the nicest Ondioline you will be able to purchase and find for sale. There is over 100+ tech hours involved in the restoration of this machine from two of the leading Ondioline specialists, primarily restored by Daniel Kitzig in Germany and assisted by Stephen Masucci in New York. This was restored in collaboration for Forgotten Futures, a non-profit set up by Wally De Backer a.k.a. Gotye, who is the leading authority on Ondiolines and passionate caretaker for preserving these beautiful instruments. You can read more about Ondioline history on Forgotten Futures Music.

This Ondioline is 100% fully functional and sounds fantastic. Ondioline’s are a very unique monophonic tube synthesizers capable of a huge range of expression due to the exponential volume lever to be operated by left knee in player’s sitting position, as well as large combination of tone controls through the sliders, the vibrato built into the keyboard (left/right movement) and the tap sensitive triggering ribbon. Add to the special expressive design the beautiful art-deco inspired wood cabinet housing and you have historic instrument that is as gorgeous in looks as it sounds.” Click here to visit listing on eBay

Sequential Circuits Pro One

“I have listed this Pro One as mint because that really reflects its condition, both in and out.

Only one previous owner and has been looked after extremely well. This particular pro one has been fully upgraded to modern specs including:

– New Fatar Keyboard (same as new pro 3)

– New Knobs

– Kenton MIDI Retrofit

These upgrades really bring the synth to a whole new dimension of playability and programmability, especially with added MIDI.

Aside from all of this.. it also comes with a hard flight case which on its own is worth over £100.

All pots have been cleaned carefully with contact cleaner and the unit has been claibareted within the last year, no repairs or service ever needed. Very minimal dust when the lid was open.

I would almost list this as B-Stock its that good, by far the best of all of them online at the moment. so buy with confidence in knowing that you’ll get years out of this classic beast. Will be dusted well before collection ;)”

Yamaha CS5

” The Yamaha CS5 is great for analog bass and gritty sounds. A simple design, easy to use and still sounds great!

Due to the age of the synth there will be some natural wear on the synth as it’s been passed from owner to owner however, it is in good condition.

There are a few things you will need to consider:

1) The HPF/BPF works

2) The LPF works but;

a) when fully clicked into place, the sound is crackly/fuzzy
b) to get a clear sound however, you’d need to have it in between the LPF/BPF (hope that makes sense)

3) The plug cable is slightly loose but it is safely fixed to the instrument, so it just needs to be handled with care.

With all this being said, getting a service may be an option for you too at some point.”

E-mu SP 1200 Project Machine

” Here it is. I never thought that this day would come. This is the ultimate SP1200. This is the 2nd of 2 that I have owned through the years and this one was the best.

It is being listed as for parts/not working because of the vintage nature of the instrument in that they do have their quirks and will need tech-ing in the future and I do highly recommend a full service by someone like FORAT. That being said on check everything works as it should on last power up. I have a handful of floppies around 20 to throw in as well (people like the Lotherak SD card thing, but I’m telling you floppies is where its at, nothing like sharpeing the label when you finish the beat).

I’ve replaced all of the buttons with black buttons, and replaced the pads with NOS pads, and all of the slider were replaced with new ones. The LEDs were replaced with white ones. The floppy drive works great and I will include 20 floppies to get you going. The other SP I had was a little noisy on the power supply, but this one is super quiet. The screen is bright, and the filter chips have also been replaced with NOS new old stock ssm2044 chips which cost me I think it was around $100 per chip. Includes a replacement set of NOS pads ($200 worth). The Jazzcat sample input monitor mod ($100) is installed and can be unplugged to disable. This allows you to monitor while sampling without reading a mixer. This one has smooth sliders and fat fader caps.

This machine was taken care of and you won’t find another package like this for sale. I’ve seen many go through websites, and there’s a lot of questionable issues that come up. They almost always need some sort of repair. For example the first one I got needed all of the buttons replaced, but the seller said it was in perfect condition. Luckily, I’ve been repairing vintage synths for years and could take care of the issues that came up. I always use Cardas quad eutectic silver solder on all of my vintage gear repairs and mods.”

Yamaha SY77

“Firstly, please know that I am an amateur with synths. There are waaayy too many buttons and features for my acoustic guitar mind, so please understand that I am doing my best–and don’t take my explanation of what works as 100% true. No matter what, I am selling it as is, for parts or repair.

It took me a while but I figure out how to produce sound from the keys. All that I am able to tell you about the functionality is what you see in the video.

Every key works but the A sharp key on the right is sticky. Others possibly are sticky as well but they all seem to respond the same to me.

There are a few marks on the keys on the right (pictured).

The screen and its brightness seem normal to me.

I don’t like how the some of the buttons feel and a few are a little sticky as well.

The rotating selector works and the sliders seem to work, as well as the modulators.

There was a disk in the drive so I attempted to access the information on it but I was unsuccessful. I did hear the drive try and engage, but again, I have no idea what I’m doing…

No inputs were tested other than mono.

Has some scratches, scuffs, and overall signs of wear from playing gigs.”

Yamaha CX5M

“I am original owner, purchased 1984 when it first came out. I then purchased the SG05 upgraded module installed as shown (Original SFG01 module also IS INCLUDED! ) giving extra features and MIDI in capabilities, and eliminating the need for the YK series keyboards!

I used the included COMPOSER cartridge to create complex multitimbral songs, and some monster real time jams…then after a little over a year of light usage, I put it in storage.

I am moving soon, and cannot take a bunch of my vintage gear with me so I hope someone will enjoy this clean, very well preserved kit.

PLEASE NOTE ! INCLUDED is the original SFG01 Module (easily swapped with only one screw) as shown in the last picture (SFG01 module is not shown in Main Photo) : IT will give you an (upgradable) spare module.

This 4 operator module is capable of truly amazing FM sounds, in addition to being an early beast of Konami video games and graphics, (which I never used it for that) but there are still

incredible 3rd party patch data available to this day, if you dig a little..or, for the adventurous, program your own with INCLUDED Voice Editor.

I very carefully have had it in dry closet storage nearly 40 years now, in case I needed it again… I TESTED it via external MIDI keyboard, utilizing the “call_music” command. and it still functions perfectly playing the tones ( Japanese Yamaha 80’s build spells quality)

The original video RF video adapter is included, as well as the cassette tape interface cable, which I have not tested , but worked fine last time I used them (requires cassette deck and/or TV/ monitor capabilities)

I am not an MSX Basic programmer perse, but a valuable extra included is the MSX programming book I purchased as well… as shown.

At 1984 , I simply could not believe how cool this MUSIC COMPUTER was, and actually still is ! If you can write music, the included COMPOSER software, can take you in interesting directions as well.

In addition to tape backup, which was very reliable for me,and all I used, there were other backup drives available, which may still be obtainable, but I think other storage/load data methods may be more efficient…sysex mabe ? I think there are some utilities available for this function….at least there used to be !

Keep in mind, the SFGO5 can do up to 8 part mutitimbral, and combinations of that, and accepts MIDI in, unlike SFG01.

Manuals (4) show some minor wear, but are all intact, except FM Voicing Prrogram has back cover page missing (superfluous) , and COMPOSER manual has back cover missing and 1st two pages missing only. MSX book is in excellent condition .” Click here to visit listing on eBay

Korg DW-8000

“Korg DW-8000 Programmable Digital Waveform Synthesizer w/ Case & PS-1 Pedal READ. The synth does work it does power on but it does have some issues. Sometimes the number display doesn’t work correctly, some of the buttons stick from when someone had an adhesive on it, and the stick on the left side has broken/fallen into the unit. It probably would work it could just use a little love. It also is coming with the ps-1 pedal, the power cable, and a travel case that it will be shipped in. ”
