Ok, I have an active preamp, a Carvin, and the J45 Bill Lawrence pups I just got in. My circuit board in my bass I have S, B & R for each pickup. Shield, Ground and Hot I'm assuming since the thickest black wire (from pickup) is going to S, Black to B, and Red to R. My new pups I have Ground (Blue and Black) and White (Hot). I'm assuming....Blue and Black (from pups) to B, and White to R. And just skip on putting anything in the S/Shield spot? OR...should I wire one of my grounds to Shield (S) and one of my grounds to Black (B)? Any help here?
