The latest BOSS guitar synthesizer products feature the Serial GK digital interface, a newly developed connection method that delivers evolved performance over the analog 13-pin GK interface used in earlier BOSS and Roland guitar synth and modeling products. The GKC-DA GK Converter allows you to drive a 13-pin GK device such as the BOSS SY-1000 or GP-10 using the Serial GK output on a GK-5 or GK-5B Divided Pickup or the GM-800 Guitar Synthesizer.

  • Converts the Serial GK digital interface to the classic 13-pin analog GK interface
  • Serial GK input and 13-pin GK output
  • Instrument input for passing normal guitar/bass pickup sounds to the 13-pin output
  • Compact and rugged metal design
