Korg Polysix

“Korg Polysix Vintage VCO Analogue Synthesiser – UK plug, 220V.

The Polysix is one of the few vaguely affordable, old-school VCO synths still available. Back in 1981, it was supposedly Korg’s attempt to challenge Sequential Circuits’ Prophet-5.

This particular Polysix has had a lot of studio use in the last few months and would probably benefit from a service. Still, considering that the synth is nearly 40 years old (so CV only), it has behaved extremely well.

The only practical issues I’ve had with it:

– – The arpeggio button and patch selector button 7 sometimes need a second press.

– – Keys C0 and D0 tend to double-trigger.

Cosmetic issues:

– – A handful of the patch selection buttons sit slightly deeper into the synth’s metal frame than the others (see pictures). All function.

– – A few of the keys at the treble end of the board sit at fractionally uneven heights. You don’t notice when playing, though.

– – The wood veneer on the side and front panels could do with re-gluing at the edges.

– – There’s a noticeable scratch on the synth’s metal front panel (pictured).” Click here to search for synths on eBay
