Korg Poly 61

“Works good. Some damage to bottom edges. Joystick is bent. Number 1 button sometimes re-triggers. See pictures.

This was Korg’s answer to the Roland Juno-60 and it looks like a Juno-106 but the Poly-61 is more interesting in many ways.” Click here to visit listing on eBay

Korg Lambda

“From the tech:
“Ensemble makes constant drone noise, lowest D#. When tremolo is on the signal is cut.
Pin 20 of IC on Module 7 has been disconnected. It is internally shorted to pin 19, causing tigger/decay circuit of D#1 to not function. IC on module 2 needs replacing. Part cannot be easily found besides 2nd hand (ebay, etc). AMI S10430 Divider-Keyer. D#1 trigger line still connected to module 4. Needs S10430 IC.”” Click here to visit listing on eBay

Korg Poly 800 II Project Machine

“I used to play this synth regularly and have owned it since the late 90s but when recently trying it, it only seems to power up using batteries (not included) rather than via a PSU. It produces sounds although doesn’t seem to have retained the patches and saving sounds hasn’t been tested.

Being sold as a project rather than working synth as I don’t have time to diagnose and sort out the repair and am having a clearout.” Click here to visit listing on eBay

Korg mini-Korg

“Vintage Korg MiniKORG 700 Vintage Analog Synthesiser (1975) Synth.

Great condition for age !, odd knocks here and there but great working order.

Due to the age and weight , I would prefer collection but can try my best to box the synth if you would like to arrange a courier.” Click here to visit listing on eBay

Korg Mono/Poly

“Operationally everything works as expected. One or two pots in the filter section (EG and track in particular) had become glitchy and showing symptoms of requiring a good clean. The unit has therefore been recently stripped and rotary controls and key contacts have been cleaned. At the same time tuning has been re-calibrated. This work was undertaken by Electrofix (Bristol).

Cosmetically the keybed and top surface of the synth are in good condition for the synth’s age. The side cheeks have at some time sustained damage on the corners and might benefit from repair or replacement.

At some stage there has been a modification in the form of an additional switch (visible to the left of the Korg logo on the top panel and above the main output volume knob). This purpose of this switch is unclear, the wiring links to the CV in jack – when not engaged the MonoPoly operates perfectly normally.”

Yamaha SY22

“Yamaha SY-22 61-Key Vector Synthesizer, Very Good condition. Light wear from regular use, previous owner engraved name on synth & power supply. A peculiar 90s Yamaha synth, designed around the concept of Vector Synthesis, allowing you to combine two FM sounds & two sample-based sounds, controlling the blend with the Vector Control joystick. Sound-wise, it’s a pretty versatile machine if you’re willing to sit with the extremely-Yamaha buttons & screen interface, lots of wild sounds & modulation capability within. Despite having no filter, the onboard FX are also plenty of fun to process sounds with too! Includes original power supply.” Click here to visit listing on eBay

Yamaha DX21

“Yamaha DX21 keyboard synthesizer working. I have a Motif and no longer need this . It has been sitting in the closet for a few years so when I fired it up I had to reload the patches from the onboard memory. Worked like a charm. Probably needs the onboard battery replaced. Lots of videos on you tube showing how to do it. LCD screen starting to “bleed” around the edges, doesn’t effect it’s usability at all. You can find back-light replacements on Ebay for under $30. Classic Yamaha sounds. I will include a printed users manual with it.” Click here to visit listing on eBay

Yamaha DX27

“Travel back in time with this vintage synth. Made by Yamaha in Japan in the late 1980s, it’s a Yamaha DX-27 synthesizer. When turned on, the display reads CHANGE RAM BATTERY. So, it doesn’t work. The display comes on. Some sounds can squeak out, but that’s about it.

The prior owner was a retired engineer who takes great care of his stuff. So, it hasn’t been abused. It just needs some service.

It’s in fine cosmetic condition. The keys, everything, are in fine shape.

Comes with the original three DX27 manuals, plus the original brochure. Comes with the original foot pedal. The power supply is not original, but is the correct power supply. Comes with sheet music bracket.” Click here to visit listing on eBay

Sequential Circuits Pro One

“This is a Sequential Circuits Pro One synthesizer.
I am including a DI box in the package (as this eliminates audio hum).

The main circuit board was built in April 1982.
The serial number on the board and the one on the casing don’t match, which would suggest to me that the synth is a combination of two previous synths.
I have made a few improvements / fixes to the synth since I bought it:
A complete clean inside and out. All switches have been cleaned as have all key contact points.
Some capacitors have been replaced.
An internal ribbon has been replaced (bought from Wine Country Productions Inc).
I have bought wooden end cheeks for the synth, since these were missing.
I have also replaced a mod wheel (which was broken) with a clear acrylic wheel.
There is audio hum. Apparently, this is a very common feature of the Pro One and is due to a ground loop (an original design oversight).
The DI box eliminates the hum, and this is why I am providing the DI box with the synth.
I’ve tuned the synth using the variable resistors (pots). The tuning is pretty good across the keyboard, but will no doubt need readjusting from time to time.”
