Frustrated that these pots were no longer available from Korg, Parts is Parts and others, I booked production time with the original factory: Omeg of England.

This is a Brand New 7 piece potentiometer kit for the Marshall Factory UK made Korg Vox AC15TB and AC30TB amplifier.

The Original "OMEG Limited" Company of England was commissioned to produce potentiometers based on the original Korg Marshall OEM tooling specifications. This batch was manufactured November 2025 specifically for the UK Korg AC15 and AC30 with no individual pots available outside this kit.

Why this type of Potentiometer?
The OEM pots are designed with a unique metal bracket incorporating 4 stabilization corner spike pins providing a 4-point PCB support. These metal  bracket corner spike pins are crucial support points for the board to properly anchor to the metal chassis. There are no other potentiometer as an exact drop in replacement. Without this type of design, techs are forced to use nylon standoffs to provide the board to chassis support.

Note: The early printed circuit board of the Korg/Marshall AC30TB incorporated a single green ground wire to the right of the board (later versions used 2 green ground wires). On this early design the Top Boost Brilliant volume pot is a ground trace and a critical ground point that only the 470K Log B pot can accommodate via the 4 corner bracket ground spikes.
