I have a plug on my bass, it as 5 pin like a midi out. It might be a DI out or something. It's not wired. the guy who used to own the bass have no idea what it is, I tried to reach Nicolas Tung I can't find him. I E-mailed Micheal Tobias, he said he havent heard of Nicolas for the last 8 years! And Micheal have no idea what it might be. Anybody know what it might be? Here's a picture, we can't see it much though.
