Korg 770 Analog Monophonic Synthesizer 1970s

This is the Korg 770 Analog Monosynth.
The predecessor of the MS-20.

It has retrofitted new LED filter sliders in green to match the power light.
Original cord replaced w/ a 3-prong AC power jack.
No other mods.  It's still essentially a stock unit.

This is a 110V AC power requirement.  I'll include a power cord.
Looks are rough, like a bulldog chewing on a bumblebee.
If you're still reading this, you don't need a showroom specimen.
You like your synths player grade, w/ tons of character.
This Korg 770 is ready to rock your world.
