Korg Resale Value Guides

3 guides to what used Korg is worth — the price at each condition grade, which lines hold their value, and how to date or identify what you have. Korg’s resale is split between current workstations and the vintage analogue synths, and the second group behaves like collectable equipment rather than musical instruments.

Which Korg pieces hold their value

Vintage analogue synthesisers such as the MS-20 and Polysix, which are collected and have risen substantially
The Volca and Minilogue ranges, which are affordable, current and sell quickly
Instruments complete with their original power supply, which are frequently proprietary and hard to source
Units with working keys and sliders throughout, since the controls are what wear on synthesisers

And what pulls the price down

Scratchy or unresponsive sliders and potentiometers, which is dirty contacts and usually cleanable but reads as a fault
Failed battery-backed memory on older instruments, which loses the stored patches
Corroded battery compartments on vintage units, which is a known problem on some models and damages the board
Missing power supplies, which on older instruments are specific voltages and polarities rather than generic

Identifying and dating yours

These are the checks that decide which end of the range a piece sits in, and they are the facts a serious buyer will ask for:

The model is on the front panel and the serial on the rear — quote both, since vintage values are model-specific
Play every key and move every slider, then say plainly which if any are noisy or unresponsive
Open the battery compartment on a vintage instrument and photograph it, because leakage there damages the circuit board

WishThrift does not authenticate or inspect anything. Condition and origin are described by the seller against five grades — what each one means — so photograph the markings above rather than asserting them.

Frequently asked questions

Is used Korg worth buying?

It depends far more on the line than the label. Korg’s resale is split between current workstations and the vintage analogue synths, and the second group behaves like collectable equipment rather than musical instruments. Each guide below says which Korg lines hold their value for that item and which have almost none, so you are comparing like for like rather than paying for the name alone.

How do I check a piece is genuine Korg?

The model is on the front panel and the serial on the rear — quote both, since vintage values are model-specific. WishThrift does not authenticate, inspect or grade anything — condition and origin are described by the seller, so ask directly and expect an answer. A seller who has the item will send a photograph of the marking in minutes.
