What I didn't put in the callouts were the trimpot gain controls for the bass and treble pickups. I made this in about 10 minutes, and so it's as good as I could make in that short time.
We were worried from some stuff we heard that someone had been inside this bass, but when we opened it up, nearly all the solder joints were clearly done by my dad, Ron Wickersham.
We're going to have the bass back again in the near future to finish the documentation of it. The low pass filters go really really low, like you can make the E string almost disappear if you set it right (or is it wrong?) Anyway, there is a lot under the hood!
