Korg Audio Interfaces Resale Value

Korg audio interfaces: price by condition

Seller-declared grades, sterling with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). What each grade means.

What holds its value across Korg

• 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

What pulls Korg resale value 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

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

What lifts any audio interface, whatever the label

Interfaces hold value reasonably but are tied to driver support, so an unsupported unit is worth far less regardless of sound quality.

• Current driver support for modern operating systems
• Clean, quiet preamps with no channel noise
• All original cables, power supply and software licences
• Higher channel counts and better conversion

And what pulls one down

• Discontinued drivers, which make the unit unusable on new machines
• Noisy or dead input channels
• Failing connectors and loose sockets
• Older interface standards no longer fitted to computers

Working out what yours is worth

1. Confirm current drivers exist for the latest operating systems
2. Record on every input and listen for noise
3. Check every socket for looseness

What to state in the listing

• Brand, model, generation and connection type
• Number and type of inputs and outputs, and whether phantom power is available
• Current operating system driver support
• Whether the cable, power supply and any bundled software are included

Brand, model and I/O: “Focusrite Scarlett 2i2 3rd Gen Audio Interface, USB-C”. Generation matters because driver support differs. State the input count and whether the preamps have phantom power, which is what recording buyers need.

Preparing and photographing it

1. Note the model, the number and type of inputs, and the connection: USB, Thunderbolt or FireWire.
2. Check the manufacturer still publishes drivers for current operating systems and say what you find.
3. Test every input and output, all gain controls, and the phantom power.

1. The interface from the front, controls visible
2. The rear panel showing all inputs and outputs
3. The connection port and any bundled cable
4. Any worn label, damaged socket or scuffed case

When it sells best, and handing it over

Steady all year with a Christmas lift. Recent USB models sell within days; older FireWire units sell slowly because of connectivity.

Compact and easy to post. Include the correct cable and any power supply, and photograph what goes in.

What buyers ask

Why are old analogue synths so expensive?

They are collected as well as played, production ended decades ago, and the sound is sought after. Working original examples are genuinely scarce.

Are scratchy sliders a serious fault?

Usually just dirty contacts, which can be cleaned. Say honestly which controls are affected — buyers who know synths expect some of this on older instruments.

How much is a Korg audio interface worth?

Roughly £48 to £240 depending on condition, against £40 to £200 for audio interfaces generally. The identification points above are what move a listing to the top of that range.

What the fees would take elsewhere

At the mid-range £144 for a Korg audio interface, against what the commission marketplaces would deduct:

Seller-side rates verified 26 Jul 2026, percentages only — the per-order and processing charges those platforms add are excluded, so the real gap is wider.
