Help with wiring!

[attackbass]

I've got a Delano preamp on its way to me and it looks simple enough but I am confused as to what to do with the various grounds coming off the tone, volume and preamp.

Do I just send the ground from the blend to the volume and then to the jack input and also send the preamp ground to the jack input?

Do I need to wire one of them to the bridge?!

Usually I can wire passive instruments but not sure what I am to do here as it's not clear in the Diagram (to me)! 

 

Here is the diagram

Star grounding is the best option ever.

Thanks for the link and the info, I think I know what to do now hopefully!

Great article - cleared up a lot of stuff for me, especially star grounding - I kept looking for the grounding jumpers between the pots  before reading the text about a shielded pickguard providing the ground connection.  I didn't realise that adding ground jumpers could increase noise!
