Korg Mono/Poly

” Here we have up for sale a Korg Mono/Poly Keyboard Synthesizer WORKS – Fix it or Part it!

Our Synthesizer is in GOOD VINTAGE condition, showing normal use marks with some corner damage – and 7 of the keys do not perform correctly. They are numbered in the pictures – with description of the misfunction listed below.
We do not have all of the correct equipment to completely test this unit.  

Nothing rattles when moving the unit.
We know it powers on, with no issue and completely silent. 

All of the keys, except one, depress and come back with a nice amount of spring.
1 – WORKS – but gets lightly stuck when pressed
2 thru 7 – does not make the board light-up

EVERY SINGLE flip switch moves perfectly with the correct amount of resistance to hold the selection.
EVERY SINGLE knob turns smoothly.
The WAVEFORM and OCTAVE knobs, which have selective stop points, stop in the appropriate spots and hold.” Click here to visit listing on eBay
