I just built my first CBG with one of these under the bridge. I cut the connector off and soldered the lead to the volume pot.  the center wire is + and the shield is -.  Works good with no preamp. I cut a slot in the top of the box and put the pickup in the slot and have a brass bar for the saddle resting on top. I have no experience with a cello, though.  I used this pickup from  CBGitty  https://www.cbgitty.com/cubecart/1pc-ukulele-rod-piezo-pickup.html

  This bridge has a rod under the arched bone saddle, soldered directly to the input jack

excellent. thanks randy for all your help, your design shows definite proof of concept. and thanks for the info bruce. i needed to know the polarities and don't have a multimeter.

the guy selling them said i wouldn't be able to dismantle the cable, but i had a suspicion he just didn't know how sneaky we are :D

I cut down rods all the time...a pair of sidecutters and snip it on the side of the rod...what i have is one of those special input jacks for the rod plugs. Then when i snip the rod shorter i can test it out right away by just tapping on it. If it doesn`t work i know to just resquare the cut end with pliers and that works. The shortest rod i ever made was 1 1/4" long for this 2 stringer...plus it`s one hell of a neat bridge...lol
