Frequently Asked Questions
No, the GKC-AD is specifically for Serial GK systems. The GR-300 uses a different, older interface.
Absolutely not. It only provides power *to* the adapter itself; it does not power your pickups.
BOSS has designed this to be transparent; any latency or signal loss should be negligible, allowing for a clean parallel signal path.
