Up for sale is a rare gemstone of Japanese analog synthesis: the Kawai SX-240. This 8-voice, dual-DCO powerhouse is in excellent cosmetic and functional condition, making it a dream find for serious synth enthusiasts and professional studios.The SX-240 is famous for its lush chorus, unique brassy tones, and its ability to split/layer voices (giving it a massive sound that rivals the Roland Juno and Oberheim series). This specific unit has been fully upgraded to overcome the typical limitations of vintage gear.
Key Features & Upgrades:

  • Tauntek Firmware Mod Installed: Upgraded with the famous Tauntek firmware, which vastly improves MIDI implementation (allows CC control over parameters, fixes original MIDI bugs, and enhances stability).
  • Fully Serviced: Professionally inspected, recapped where necessary, cleaned, and calibrated. No battery leakage issues. All sliders, buttons, LED displays, and keys work perfectly.
  • Excellent Cosmetics: Beautiful wood side panels and a very clean front panel with minimal signs of use for its age.
  • Hard Case Included: Comes with a rugged, high-quality hard case ensuring the synth stays protected in your studio or on the road.

Shipping & Packaging:

  • Worldwide Shipping: Available to international buyers and collectors.
  • Professional Packing: Box-in-a-box method with heavy-duty bubble wrap, foam corner guards, and rigid cardboard to ensure absolute safety during transit.
  • Safe Delivery: Fully insured and tracked shipping.

This is arguably one of the best-sounding and most versatile poly-synths of its era, now perfectly reliable thanks to the service and Tauntek upgrade. Message me for any questions or a precise shipping quote!
