# BOSS GKC-AD 13-pin analog-to-digital converter

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. This GKC-AD Converter allows you to drive the Serial GK input on the GM-800 Guitar Synthesizer from a MIDI equipped electric violin, viola, or cello from ZETA or Cantini. A BGK serial cable (sold separately) is also required for operation.

-   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
