I'm afraid Mike is right. They were very kind but couldn't help me to get the 3 bolt plate.
Anyway, I found a place in São Paulo that - maybe - could make me a new plate. They don't use to make this kind of thing, especially in "low" quantities. It might take some time but they agreed to make me one.
Just need the trace in PDF or CAD.
All I wanna do is get this bass working again! Gonna post soon.
hehe, it does exist, believe me.
Pics were taken by the guys at guitar shop.
As soon as the bass arrives here I'll post many more and audio clips as well.
I still have to buy the string mute. EBMM costumer service is taking care of it!
So see you soon ok?
