Boss GKC-DA Serial to 13-Pin GK Converter

With a Serial GK input and 13-pin GK output, this box converts Serial GK signals to the 13-pin GK format used by legacy gear like the Boss SY-1000 or GP-10.

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.
