LUCKY !!!!
B-Quads are AMAZING. I own one that I've bought from Derrick Cook recently from the Peavey Building #2. I have the complete bass minus the preamp. It's the exact color I was looking for, too. I have owned a few over the years and they are pretty much the only bass you'd ever need.They do everything.
Did you ever figure out a preamp(s) plan?

Never intended to, I was just picking up cheap basses. One day it dawned on me i'd about half the models released,thought was sell them or see if the others came my way.
