Wiring diagram for Nanyo SGC 320

[TheGreek]

I've emailed the Bass Centre and I'm awaiting a reply but in the meantime does anybody know where I can get a wiring diagram for the preamp in a Bass Collection Nanyo SBC 320?

I have never seen one. I think there is a lot of variation in the design. My 3 all look different, and the original electrics seem to be the only weak spot with these. I have a spare artec 3 band somewhere if you want to give it a try. I now have a Nordstrand in my main bass and that is fantastic.
