Mint condition Boss GKC-DA interface for controlling and playing Boss 13pin units VG99, GK33, GP-10 etc
using the newer GK-5 pickup.
i.e. SERIAL to 13PIN
I'd already sold my GP-10 by the time it arrived, so it's never been used.
Lived in it's box, in a cupboard, in a smoke free home.
Still boxed with PSU.
Willing to post.
Any questions, please ask.
This may be also be advertised elsewhere.
