Boss' newest guitar synthesizer offerings showcase the Serial GK digital interface, an innovative connection technology that delivers improved performance compared to the older analogue 13-pin GK interface utilised in prior Boss and Roland guitar synthesizers and modeling products. To connect the Serial GK input on the GM-800 Guitar Synthesizer from a Roland GK-3 or GK-3B Divided Pickup, or an instrument equipped with a 13-pin GK output, you can use the GKC-AD GK Converter.

  • Converts the Serial GK digital interface to the classic 13-pin analogue GK interface
