Help: EBMM 2001 JP6 G String Piezo Saddle

I own a 2001 model JP6 guitar (first JP model made) and I have a problem with the G string piezo saddle. When I pluck the G string there is buzzing coming out only when the switch position is on piezo or with magnetic combined (but not with magnetic only). After some checks, I know the problem is in the crystal inside the saddle. I talked with the company about buying a new saddle and because of changes made over the years one new saddle can’t be bought and I have to change all the six saddles and the pre-amp unit of the guitar! So now I’m looking for a G string piezo saddle with your help. If someone knows how can I put my hands on one in good condition for the 2001 model I will be very happy.

Thanks a lot for the help
