Korg X-911

“Up for sale is rare Korg X-911 vintage analog guitar synthesizer.

The unit appears to be working reasonably well, I noticed the TUBA sound seems to be only producing small noise somehow, but otherwise all other sounds working and sounding fine as well as all the knobs and switches working as they should. There may be a slight bad contacts on the BALANCE slider, which could probably also do with some servicing/adjustment. All the LED lights above each buttons lighting up correctly when pressed.

Cosmetically the unit is in very nice condition as you can see. There are some signs of wear and minor marks here and there, but nothing major. I’m including plenty of photos so you can see exactly how it looks.

Comes with the Original Plastic Overlay as shown.
Power cable included.”

Korg MS2000R

“The MS2000R is, of course, the rackmount version of this beast. Although there is no keyboard and no real need for one, the 16 function buttons on the front of the unit can be switched into “Keyboard” mode in which they function as keys, mainly for demoing sounds while you’re programming it. This is a really great feature since most rackmount synths either don’t allow you to hear your progress from the actual unit or they only feature a one-note demo button to hear your sounds. The MS2000 is truly a well thought out instrument for musicians of any level looking for classic and new sounds within a quality digital synth with a sleek vintage look that’ll turn a few heads!” Click here to search for synths on eBay

Korg MS2000

“For sale is one Korg MS2000 44-key analog modeling synthesizer. This is a digital synthesizer which was designed to emulate the sound, features, and control/modulation possibilities of a classic analog synth. As with many Korg products this synthesizer is very well built and includes a number of innovative features and surprisingly flexible routing (… and it sounds amazing!). It has been well cared for in my smoke-free home studio for many years. It has never been abused or gigged although I’m sure it would do fine if you were to bring it on the road.

Condition (cosmetic): Good… Two of the keys were chipped and thus replaced a few years ago which is why they look whiter than the others in the photos (the original keys have more of an off-white appearance). Functionally it is in excellent condition – there are no issues with any keys, buttons, or knobs. I am including the original power supply and user manual. ”

Korg MS-10

“Later version with trigger button. No corrosion. Keyboard connections re-soldered. Modulation wheel works. The switched jacks all work. Pots are mostly quiet.
This synth was sidelined for many years due to a couple of non-operating keys and I didn’t have any CV equipment.
This month, I opened the unit and carefully repaired the cracked solder joints where the key contacts meet the switch board. I reheated all of the joints to make sure they don’t fail.
The interior is very clean and I carefully cleaned the outside of the unit including the knobs.
The plastic left side plate of the case was cracked at the front, so I reinforced it with glue. See image. This does not affect the rigidity of the case.
At first, the pots were noisy but they quieted after using the synth for a few hours making sure all the functions worked and remembering how much fun it was.
The Pulse Width modulation operates well as do the LFO panel outputs and the switching jacks do what they are supposed to. I’ll throw in 4 home made patch cords, so you can play with the modulation immediately. ”

Yamaha DX7 II FD

“Here is a classic DX7II-FD. This synth is in good cosmetic shape other than the damage that was received while in storage. Some heavy items were placed on top of the keyboard, resulting in damage to the bottom two octaves of keys, and to four of the buttons (two of the voice mode select buttons, the EG Copy/Store, and the Play/Performance button. I’ve been playing the synth all morning and it still sounds great. All of the other controls seem to be working just fine. Please see the photos to examine the damage.

This is a legendary and fantastic sounding synth. I’m reminded how good it sounds… and how much better it sounds than the emulations that are out there… today as I’ve been playing around with it. These are always pricey to box up and ship, so local pickup in the Lehigh Valley or NYC area is possible.”

Yamaha FB-01

“You are looking at a chance to own a unique / modified Yamaha FB-01. The FB-01 is part of the famous FM series such as the DX7.

Cosmetics: This is one of the nicer units I have seen, apart for a few specs the black paint is in excellent space. All 8 buttons work with ease.

Modifications: Updated audio signal path with hi-fi op-amps, and a battery holder for quick future battery replacement with no soldering required.

All Yamaha FB-01 units have incorrect parts that were installed straight out of the factory. The manufacturer installed these lower quality parts despite what is written on the original schematics, reducing it’s sound quality potential, and it is noticeable like day and night. The modifications installed on this unit unlocks the higher frequencies, better known for the famous bright and sharp sound of FM synthesis that Yamaha initially developed. In addition I installed superior quality OpAmps that not only reduce noise with ultra low distortion but also boosts volume to a reasonable range. To save time in the future, I also installed sockets for the OpAmp chips, just in case there are any other low-noise replacements to try out (note: I do not recommend the replacement of the OpAmps unless you absolutely already know what you’re getting yourself into).”

Yamaha SY-1

“I’m having a bit of a clear out and selling my lovely Yamaha SY1 synthesizer.

This was Yamaha’s first synthesizer from 1974 although it seems advanced in that the keyboard has aftertouch which can be routed individually to the filter or wah-wah, the amp or to produce vibrato, or all three. There are 28 preset sounds (Growl Pet being one) but you can also engage manual control over the filter cut off and resonance, the amp envelope, vibrato, pulse width and portamento, which can then be edited using the sliders and knobs on the control panel. You can also slide into notes using attack bend.

Once mastered this is a very expressive synth to play and though I have Roland SH1000 and 2000, I personally think this is really head and shoulders above them control wise (and it never double triggers!). Put through some dense reverb and delay you can almost make it cry like a guitar – there are some good demos on YouTube.

The synth is in lovely condition with just a few small paint chips on the front corners (seems to be very common on these synths) and a couple of marks on two of the keys. The wood is really nice and clean with no marks, I hope this comes through on the photographs. I just don’t use it as much as I once did.

The synth also comes with about 3 mtrs of power cable which seemed to be standard then.”

Kept in a smoke and pet free studio since I bought it second-hand around 5 years ago.

It is modified with the bonus of 4 x 1/4 inch inputs for external drum trigger pads for live playing. Trigger pads can be bought from Roland et al.

There is one plastic button/top missing – for the ‘Slower’ tempo button. I have not had a chance to replace it. But I am sure you can buy a replacement online and put it back on yourself. You can still trigger the button without it though. ”

Sequential Circuits Pro one

“ALL of the oscillator chips were replaced (including the LFO) with NOS CEM chips.
Also the power supply was checked out, tuning calibrated and I have replaced ALL of the keyboard’s rubber bushings.
This Pro-One has the more desirable “J-Key” type keyboard which is considered much more reliable.
Once I replaced the bushings the keyboard was a LOT quieter and had a much better feel to it.
Repair work was professionally done by DFX in Salt Lake City (they make great boutique pedals too!).
Cosmetically a 9+ out of 10 it is a beautiful thing to behold! There is one scratch on the back, and normal wear and tear marks on the wood sides (which can easily be sanded out).
Awesome powerful sound, very ballsy and aggressive with its famous modulation capabilities,sequencer and arpeggiator.
Note: There is one knob currently missing (the volume knob) but I will purchase a replacement for the winning bidder and have it sent directly to you.
This is a great example of 1982 synth technology, VERY RARE and COLLECTIBLE, ESPECIALLY SINCE I HAVE THE ORIGINAL BOX it came in and the ORIGINAL MANUAL as well.” Click here to search for synths on eBay
