I noticed a "touch the 1/4" jack and it goes away" hum (but no string sound degradation) on my Variax. There was no continuity between the strings and the 1/4" jack. Took out the main board and there is a green wire (as well as a short stub of bare stranded wire) coming from the bridge area independent of the ribbon cable for the piezos. This is connected to the strings so should be tied to ground somewhere, unless it was added later. Any ideas where it should connect? L4, which connects between ground and the 1/4" jack ground to activate the battery when it is plugged in, has been removed and there is a bit of wire soldered across it. I'm guessing that's the broken end of the green string grounding wire. The part number of the PCB is 35-00-0137 Rev. E dated 08/02.
