DX100

“Yamaha DX100 Synthesizer Digital Programmable Algorithm from 1986

In working condition.
I tested it with head phones and it works fine. When I connected it to my audio interface it started making a weird, kind of buzzing sound. I also connected it to another amp and it worked fine. The volume switch makes some noise. A component cleaning may fix that up. Some cosmetic flaws, but nothing serious. Overall in good condition.”

“This Yamaha DX100 synthesizer is a vintage gem, purchased new in April 1986 and has been well-maintained, ready for your musical inspiration.

With 49 keys and a variety of input/output ports including cassette, breath control, 1/4″ phones, 1/4″ mono output, DC 12V in, MIDI In/Out/Thru, Foot Switch, and contrast, this keyboard synthesizer is perfect for any pro audio equipment needs. It also features a pitch wheel, display screen, modulation wheel, and is battery-powered (120VAC adapter included).

The synth is in excellent condition, both cosmetically and functionally. Three weeks ago (August 2024), I replaced the graphite rubber keyboard strip, and all the keys play like brand new. See the picture of the eBay part listing.

Also included are the original 120VAC OEM power supply, the owner’s manual, programming manual, the original songbook, and the sales brochure—making this a complete package for collectors and enthusiasts alike.” Click here to visit listing on eBay

“Yamaha dx100 FM synth

Classic 4 operator FM synth from the 80s.

Everything works perfectly apart from several keys in the first octave which can be intermittent to not working. However, once connected to a computer DAW or external keyboard via midi this is not an issue!

I have never opened the synth – could be that contacts just need a clean.” Click here to visit listing on eBay

“Up for sale we have a preowned Yamaha DX 1000 Synthesizer. It comes as pictured with nothing else included It does power in and works. It does need a battery door and a few of the keys are delayed some. It will also need the internal battery replaced so I don’t know how much of a role that is playing. Because I’m not an expert at these older vintage synthesizers, I do not know how this board fully functions. For these reasons I’m selling it AS IS FOR PARTS OR REPAIR. Thanks for checking out this listing.” Click here to visit listing on eBay

“One very careful owner before me. I’ve had it for a few years and never really used it at all, and haven’t really had the time to sit down and work it all out. The power adapter I believe is the original one, when purchased back in c1986 but is clearly a European plug. Adapter will be included. All working as expected. Small bit of damage to two buttons but doesn’t affect them. ” Click here to visit listing on eBay

“This Yamaha DX100 FM synthesizer is a vintage piece from the 1980s that will bring a unique sound to your music. With its classic Yamaha FM sound, this synthesizer is perfect for anyone in the market for pro audio equipment. The DX100 is a versatile synthesizer that can be used in a wide range of musical genres. Its compact size makes it easy to take on the go, and it’s sure to be a hit with any music lover. The DX100 is also commonly desired for its unique breath control functionality used by many popular artists. This example was well maintained and minimally used over the last couple decades. It has minimal cosmetic flaws. Only notable things are some light surface scratches and some dust. The other thing to note is the data entry slider is missing the plastic knob. Otherwise everything is in perfect working order and most collectors would be pleased with its condition. No issues from a functionality standpoint. ” Click here to visit listing on eBay

” This synth has been treasured and very well looked after, There are some faintly visible scuffs, rub mark and light scratches on the UNDERSIDE of the case (probably caused by using a guitar strap) but nothing visible on the top sides or back. The synth has been thoroughly cleaned and tested, the internal memory battery has been replaced and the main battery compartment cleaned of the decaying foam battery cushion and replaced with a new neoprene pad.

You can power it with batteries and put on a guitar strap (it has strap lugs) if you want to stand front of stage and jam along with your band mates! This synth has never been gigged, abused or thrown around. Just home use in a smoke-free environment. It really is in great condition for a 38 year-old intrument. ” Click here to visit listing on eBay

“Yamaha dx100, it needs repair. It will work when it wants to like just the right angle or just the right wiggle of the ac adapter (not included) so I will say this is more for repair or parts, or if lucky it will work sometimes. Possibly will work better with batteries, not sure I’ve never checked, and yes I used this for a talkbox carrier. So it did have the c is c patch when working. Take a look at pics, it does have body damage. Thought when working, all keys / sliders / buttons / wheels worked as they should. ”
