Moog Prodigy

“Moog Prodigy 336A Synthesizer Keyboard/Professionally Inspected & Serviced!

If you are like me, when you are buying a high-end instrument on eBay, you want a greater assurance than “It looks great to me, but I’m no expert, and no returns!” That’s why I put nearly $200 into having this Moog Prodigy 336A Synthesizer professionally inspected and serviced before listing on eBay. It is ready to gig! I took it to Music Technolgy in Springfield, Virginia, the premier Washington, DC, experts in vintage music electronics. (Check them out on Yelp, these guys know what they are doing.)

Besides an overall test and cleaning, Music Technology:

Resoldered the fatigued connection points for the keyboard and output
Deoxed all pots and switches
And removed 35 years of debris from the inside”

Roland Juno 106

“Fully restored Roland Juno 106 Analog Synthesizer working perfectly. Includes Juno 106 synth, US power cable and 1 extra 80017a voice chip.

All keys, slider caps, and buttons were removed and hand washed. Vacuumed and cleaned inside and out. All 6 voice chips had the resin removed to last for years to come. The one voice chip that was giving trouble when I purchased the unit has been socketed for easy removal in the future if needed. Includes one extra 80017a voice chip (resin removed) for replacement in the future if needed. Trouble tact switches were replaced for 1 touch operation.

This synth is my pride and joy. I am only selling this because I was recently layed off. My loss is your gain. Any questions, contact me and I will respond as soon as possible. ”

Roland MC-202

“This listing is for a like-new Roland MC-202 analog synthesizer/sequencer. It is in fantastic, fully-functional shape with only two marks on the bottom of the synth. The 202 has not been modded or altered in any way and has seemingly rarely ever been used. The 202 is very similar to the Roland SH-101, though the 202 sports a much more advanced sequencer. Even the box is in good shape. A proper 9V power supply will be included with the synth. Good luck and happy bidding!”

Roland ProMars MRS-2

“If you’re looking at this, then you know what it is. I recently bought this from a real ‘synth guy,’ who went over it and serviced it… made it good for years to come. He replaced the battery, re-capped it, and cleaned it up. If you’ve been looking for a great Promars in very good-excellent condition, then this is the one… Also probably the only one available online that ships from inside the United States. It is in 100% perfect working condition.

In the interest of full disclosure, here is a fully transparent (to the best of my ability) description of the synth’s condition, with any and all ‘little’ things that one would want to know:

All original sliders, knobs, buttons, switches, etc. are present and accounted for. There is no writing or stickers anywhere- as far as cosmetic condition goes, there are some knicks on the wooden sides (visible in pics), a little bit of tape residue next to the word “Promars” on the face plate, and a little bit of rust/buildup on some of the screws (which could easily be replaced). Also, the Attack slider in the VCF section is slightly bent, but does not affect function. Synth stays in tune and tracks well.

Also, this is the Japanese version (100V), so you may want to get the appropriate voltage converter for this baby.”

Korg DW-8000

“Up for purchase is this Korg DW-8000 Programmable Digital Waveform Synthesizer that is in excellent working condition. This synth was just cleaned inside and out and serviced. The keybed was removed and cleaned including the keys; keys still make that clacky sound which is common on a vintage DW. A new RAM battery was installed and the factory patches were reloaded. A new volume slider was installed. The finish shows some wear and a few scuffs but it really looks good overall. Fully tested and works/sounds great. Comes with power cord.”

Korg DDD-1

“Vibey, underrated drum machine with killer snare & well balanced kick.

Please note this has particular model has a couple of issues. Firstly the function 1 button (F1) doesn’t work. The contact underneath needs replacing – should be a straight forward fix.

Secondly when playing the drum buttons on the machine the kick sounds loud in comparison to the rest of the drum hits. This doesn’t happen if you are triggering it via your DAW…everything is balanced & as it should be.

I used to play this via my DAW / midi keyboard & it sounds great. All the decay, output level & tuning options work fine. ”

Korg Mono/Poly

“I do not want to sell this.

If you’re looking at this, I don’t need to intimate how great this synth is – the modulation capabilities are unique (particularly with the LFO trick, which this unit performs easily – I will show you how, if you pick her up).

I apologise that the photos look like it’s been taken in a 1970s opium den – I should have taken it to the kitchen for extra clinical, halogen-lit photos.

This works flawlessly. She retains the Japanese 110V supply, but I will provide a high quality transformer for UK voltage.

My house move forces this sale.

I have swapped knobs with the Korg mixer from the same series. It illustrates the architecture of the synth very well… If you want the original knobs back, I’ll swap it back to standard (but I’m not the first to perform this swap)”

Korg M500 Micro Preset

“This Korg Micro Preset M500 comes complete with its original manual and nine patch sheets that fit over the the controls to create specific sounds. There are a few blank ones that you can use to create your own.

It is being sold AS IS. I am not a specialist, but had it checked over by one and this is what he reported:

-All functions appear to be working EXCEPT “Synth 1” and “Synth 2.”

-In good overall cosmetic condition, except one chip on a corner clearly marked in the pictures, a few light surface scratches.

-Missing the knobs on the “Modulation Depth” and the “Momentary / Portamento” switch (but they work fine without them). ”

This tx81z comes with the X81pg programmer and US power supply.
The X81pg makes the tx81z one of most easiest programmable FM synths out there. It is a joy!
The tx81z sounds fantastic! These older FM synths have some grit and gusto that the newer ones miss.”
