Yamaha DX7

“Yamaha DX7 fm synthesizer. The original. Powers up and works through my amp. The volume control is scratchy and doesn’t work right, it is either full volume or low but nothing in between. But everything else seems to work as it should and the led display is strong. As-is. Vintage and super cool. ” Click here to visit listing on eBay

“This item was in great shape until being busted up in shipping. As you can see in side the device from the photos, nothing as far as the circuitry has been damaged and in fact still powers up and functions. A few of the keys did break where it is held together inside but all of the other damages to this unit are purely cosmetic. I am selling this for parts or repairs ” Click here to visit listing on eBay

Yamaha DX7

“This DX7 has the E! Upgrade which gives you 10 banks of great sounds. Fully functional but comes with a few quirks. You’ll notice an end is cracked and button #29 has part of the face material missing. A couple buttons take a firm press to switch sounds/perform the function but all do indeed work. The keys feel great – I flipped the springs. What you see is what you get – no manual or memory cards, etc. Shipped insured with signature required in a well-packed box.” Click here to visit listing on eBay

Yamaha DX7 IID

“- Keyboard powers on, LED’s light up and LCD display works fine.

– I tested all keyboard keys prior to listing and they all work fine.

– When selecting between internal voices and cartridge stored voices, the “internal” button does not appear to be working. Since I do not have a data cartridge for this keyboard, I have not been able to test the buttons related to selecting different voices.

– The pitch-bend wheel (left most one) is loose and wobbly, but not disconnected and it still functions okay, it’s just too loose.

– I have tested the audio output to an amplifier and that works just fine. ”

Yamaha DX7 II D

” You are bidding on my Yamaha DX7 ii D. I’ve owned this for around five years and it is in excellent cosmetic condition for a 30+ year old synth.

In the time I’ve had it, it has been kept in a pet free, smoke free home studio and stored beneath a vinyl cover which I had shipped from the States when not in use.

This is a fantastic example of 80s FM synthesis, improving on the original DX7 in a number of ways. The keyboard feels great and it’s a joy to play. The only tiny issues to mention are that the numbered keys sometimes take a second press to get the result you want, but they all work and you can select all the presets. During testing, I noticed that the left channel was weaker than the right channel. Never noticed this when playing through an amp – but it is noticeable with headphones on so I feel it’s only fair to mention it. It may be a setting on the synth, but I genuinely don’t know.

MIDI and sustain both function as they should. I’ve had this running into my interface running Cubase 10 Pro, so it is still very recordable.

I know FM synthesis can be a bit Marmite, but if you’re looking to nail the sound of the 80s, this is what you need. ” Click here to visit listing on eBay

“Yamaha dx7S synthesizer. Condition is used.

Here is my Yamaha DX7S Synthesizer up for auction.

I have replaced the internal battery with a new battery housing soldered onto motherboard which will make future battery changes a total breeze!

The initial factory sounds were lost due to ths battery so it will need the sounds loading back in or a cartridge, I don’t have the cartridge but it can be done via midi.

This is a vintage synth in great condition that needs the sounds loading boack in, all keys and case in great condition… grab a bargain with a .99p start and no reserve.” Click here to visit listing on eBay
