BOSS GKC-AD Electric Guitar Convertor

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-AD GK Converter allows you to drive 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.

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