One thing these battery capable devices that are working in different voltages through the PCB, grounding your new fantastical bonanza add-on. Yeah... no comment...

So, I found a good “re-use” Tip. See the lower right corner screw hole, that little piece of soldered copper, thats glued with a dab of hot glue and stuck to that particular screw hole. 

Why that screw hole?

Well, thats one of two main grounds the Volca’s usually have. 

Here is the one on the Volca Sample, the Volca Bass is on the back front plate as well.

So on the Volca Base it lays on top of that little hole and anything there touches the copper. So I took a snippet of Solder Wick. Thats the cleaning copper that you use to clean PCB solder out of holes and stuff. It was saturated with solder so I squeezed it flat and glued it to the edge down the back of the lil’ stand-off on the base body. Then I ran the green wire over to a 2 pin ground that I soldered by combining two pins on the PCB add-on board I mounted in the Battery compartment. 

Snipped the tips off some patch cables I had to make shorties to solder to the wick, and then over to the PCB board. 

This allowed me to daisy chain my grounds on my jacks with just one wire. Easy Peasy.
