“Ensoniq ESQ-1 – The early all metal version. This is the keyboard all over Kanye West’s College Dropout album. Really fat basses and pads. This sounded great a few months ago, but now the battery died and it only loads one program. I suck at soldering so it’s sold as-is. A new battery will bring it right back to stock.
There are a few nicks here and there but overall it’s in good condition. I tried to mistakenly clean some keys with nail polish remover and ended up making it worse. Those keys are smudged from the remover. Sold as-is needing a battery.”

“Ensoniq ESQ-1 Digital Wave Synthesizer with analog filter. Recently purchased from the original owner as a “fixer upper” as after years in storage the unit wouldn’t power up successfully. The VFD display would flicker briefly and go no further. I’m assured the synth had only been used at home and not gigged. I suspected a power supply issue, possibly needing a recap or service. I ended up swapping the keybed to repair another ESQ-1 with yellow keys.

So this listing is for an unexpanded ESQ-1 (earlier metal body version) with an unconfirmed fault and flat backup battery. The sale includes the keybed from the other unit but with all white keys removed as I planned to whiten them. You will receive all of the white/yellow keys (undamaged) and springs to rebuild the keybed which worked without any issues. Photos show what “might” be displayed on the screen when powered up; most times it will just flicker briefly. This suggests a relatively simple and low-cost repair for a competent tech. Clean unit with no damage. Selling for spares or repair with no returns.”

“Tested, working and very much enjoyed Ensoniq ESQ-1 Synth 

Fitted with sqx-10 sequencer expansion

A couple of minor cosmetic issues that can be seen in the photos:

– Plastic data entry slider knob missing (doesn’t affect operation) 
– Cart B button is missing (I think it’s actually in the synth but I don’t have time to dissemble and retrieve). Doesn’t affect usage unless Carts are being used

I originally imported this from the USA so for UK use it works with a transformer plug. The person who sold it to me had it serviced before I purchased it in 2014. 

The transformer plug hums a little bit (this doesn’t affect sound coming out of the synth it’s just the ambient sound in the studio). It wasn’t enough to bother me so I didn’t ever replace it but should be an easy replacement if needed. ”

“This is an excellent keyboard, not only because you can endlessly modify the many sounds that are available for it, but also because it’s an 8-track sequencer as well, with mixing and song-sequencing ability too. I’ve written so many songs on this keyboard over the years, and have gotten much joy from owning it. Really cool sounds are built in, and this sale includes sound cartridge #1, which initlaly came with the keyboard.” Click here to visit listing on eBay

“Ensoniq ESQ-1 Digital Wave Synthesizer – 1985 Serial Number 12389 – Very lightly used and still works well with the following caveats: (1) The integrated battery needs to be replaced. A warning is shown when you turn it on and it won’t remember any changes to sounds programmed in the internal memory or sequences recorded with the builtin music workstation capabilities until this is done. (2) Once recently it failed to work at all and the display just blinked on and off and no sound was produced. This solved itself somehow, possibly a result of allowing the capacitors to discharge. If that is the case, the synth may need service at some point soon to replace bad capacitors, which is a common or even expected problem in vintage synths. Or it may also be due to a loose ribbon cable, another common fixable issue with these synths. Otherwise it works fine, including all buttons and keys, both synth and sequencer. I played with it for several hours before preparing this listing. There are two program memory cartridges that do work as a way to store custom programs even if the battery is not replaced. ” Click here to visit listing on eBay

“This item has been refurbished twice since my ownership of it. The first repair was a problem with the display no longer lighting up, and this was due to a blown capacitor. The offending capacitor as well as the other old capacitors have all been replaced and the display now works perfectly. The second repair was replacing the lithium battery after getting a low battery warning (the lithium battery on this synth only lasts twenty or so years, and without it you cannot retain patches or sequences after powering down). The lithium battery installed was brand new and should give the synth at least 15 more years of memory. This model comes with software version 3.20 installed, program cartridge, power cord, and this version comes with the SQX-20 sequencer extender already installed, this allows 20,000 more events for the on-board sequencer. The only defect with this unit is a small hairline crack on the bottom of the F4 key, which is easily replaced and entirely cosmetic. I’ve included a picture of the defect. Otherwise for its age (1987) the synth is in impeccable condition and works flawlessly. ” Click here to visit listing on eBay
