Vintage Esoniq ESQ-1 Digital Wave Synthesizer, Sequencer Keyboard!
Works great and is in awesome condition for its age! Obviously has some wear but nothing that stops performance! Comes with one cartridge filled with plenty of fun presets!
-UPDATE-
Recently started kicking a low voltage warning every time it is powered on. I have purchased a 3V lithium battery but I haven't been able to take it somewhere to get serviced yet because it requires soldering. If you purchase I will be sure to ship the battery with it.
Obviously I'm aware the price seems somewhat high for a unit that requires service but considering the cosmetic condition and what they are worth fully functioning I believe the price is fair. I should also note that over time almost every ESQ-1 unit will run into this issue and will need its battery replaced.
