“Ensoniq ESQ-1 Synthesizer Keyboard with 13 sound preset cartridges, as-is
Keyboard powers on with bright display and makes sound.
Keys are intermittent. Some sound, some don’t, some work sometimes. They seem to get better as I play it. Perhaps it will fix itself over time (but don’t count on that). The buttons seem to operate (though I didn’t test every one). The volume and data sliders work. Cartridges that I tried load their sounds but, again, I can’t guarantee that all cartridges work. (You should use some electronics contact spray – like DeOxit D5 – on the cartridge contacts.)
This unit was in storage for years and likely suffered from less-than-ideal environmental conditions. Consider it in need of maintenance. As I say, it basically works but needs TLC. That’s why it’s sold as “For parts, not working” and as-is, as-found.” Click here to search for synths on eBay
