Copper shielding on instrument with existing bridge ground

I'm new to this shielding business, so please forgive my ignorance!

I carefully applied copper tape to the entire electronics cavity of my Warwick thumb, which has an existing wire running into it from the bridge. I also applied the copper tape to the inside of the control cavity cover.

Is there anything special that I need to do?

I was planning on soldering the bridge ground to the output jack ground and then running all the grounds from the rest of the electronics daisy chained down to this same lug.

Although in theory, ground is ground and the better ground you have the less you'll be subject to grounding issues, and copper shielding tape, applied correctly, should help shield against RF and other electrical interference, (remember that it, too, is a conductive material) you may want to check with the Warwick folks about re routing the ground to an electrically connected ground like the output jack. If you're not experiencing ground hum issues then there may be no need to change it. My old Jazz bass had the classic style bridge ground and never produced any ground hum. I considered moving it to the cavity connections but ended up leaving it as is. Someone else may have more solid info on the ground wiring for your bass though.

Oh, I think the stock setup was bridge ground soldered to output jack ground. I gotta go back and see if my "pre" pictures show that clearly. I'm doing a full electronics replacement. This is a jazzman setup btw...single coil neck with dual coil humbucker at bridge.
