so here is a pic of the ghost bridge. just a dry fit with the metric post from the customer service folks at graphtech. After searching the site, i am thinking of how to wire this thing. All the stuff I have seen uses master v/t for mag and piezo vol. Nothing with separate vol for mags , master tone and piezo vol. I sent graphtech tech support an email for help. I have to say the stock setup is awesome. These pickups sound great. the neck gives of this very jazzy tone. Still in the honey moon phase!!! At the moment I feel no rush to do anything to this beauty!!!
