[sdiy] Grounding check (OT)

Thanks to all for their help on this.

I tried doing what Rene outlined below, and I measured the resitance between the strings and recepticle at about 680 ohm. I note that this only exists when going through th e effects processor, sending the guitar directly into my mixer I'm measuring zero ohm, so it's obviously the effects processor that has the problem since I had nothing else in the signal chain.

The effects processor I am using only has a two-pronged plug (it's the stock cord so I'm assuming that's the way it should be). Anyone have a suggestion how to rectify this (perhaps I ought to just take it in for servicing) or would I be best off using the cap and resistor between the hot and ground on the guitar itself?

Thanks again!
Dave
