Korg A1 Performance Signal Processor 90's 2U Stereo Multi Effects Rack

The Korg A1 is a high-quality, versatile multi-effects processor from the early 1990s, known for its comprehensive range of effects such as reverb, delay, chorus, and more. It features 16-bit DSP with a 44.1 kHz sampling rate, a user-friendly interface with an LCD screen, and extensive programmability with both factory presets and custom patches. The A1 supports MIDI control and is rack-mountable, making it suitable for both studio and live use. 


  • This is a used unit. 

  • Physically this unit is in good condition for its age. It shows some small marks, nicks, scratches. Nothing major at all. Overall is is a nice rack! Sadly it has no rack ears though. Please see all photos. 

  • The screen looks like it has a darkish patch on it when it is turned off, but this does not affect the unit when it is turned on. The screen is bright and clear.  

  • This unit has had a minor service and a new memory battery installed. 

  • This A1 has been thoroughly tested. It is 100% functional and has no faults to note.

  • Please be aware this unit is 100V. This means it MUST be used with a step-down transformer, not a travel adaptor. If you are unsure about this please let us know. We have some great, compatible step-downs for sale HERE. They are designed in Australia for use in Australia and can be run 24/7.

  •  If you purchase from outside Australia you may need a step-down transformer to use this unit. Please contact us if you need any help sourcing the correct product.
