Hello This is my first post so first off Hi Everybody ! Ok so i am gonna rewire my washburn over the weekend and i've had these bourns pots for a while and i just opened the one and its just come to my attention that the case is infact all plastic. My set up is a pretty standard humbucker - humbucker with two vol's and a single tone. Heres the product page if its of interest to anyone. www.bourns.com/data/global/pdfs/95.pdfI was also planning on using a CTS pot for the tone to make a no load tone pot, could i ground stuff on to that as a comprimised. My mind is slighly fryed on the matter any help would be appreicated

KOL -
Welcome to the board.
To answer your question, grounding off the pots has been a standard practice for years, so it is a viable path to take. Be careful soldering multiple wires to your pots...extended exposure to high heat can do bad things to them.
Proper shielding and star grounding does have it's advantages.
Are there specific areas that are giving you grief with wiring your project?
Happy Trails

Plastic pot case, eh? I wonder if you can use a ground washer that slips over the pot shaft and has a tab that you solder the ground wires to, sort of like item #5 here: No clue what the application in the picture is, but you get the gist. D2o

I can't imagine why you would actually want the hassle of trying to collect your ground wires on a pot case anyway. Any convenient lug which connects to the output jack's sleeve, or even the jack sleeve lug itself, make much better places for star grounding. Unless, of course, you're implementing the protection cap from QTB.
A metal tab around a plastic shaft will not accomplish grounding the plastic pot case itself. The point of grounding the pot cases is mostly for shielding of the innards thereof, and is mostly obviated by installing the pot itself inside a shielded enclosure. So you are shielding the control cavity, right?

The shaft of the pot is metal only the case is plastic so i guess i could solder to the lug nut As D2o showed. The cavity is already shielded with the black paint stuff, i've even got a couple of tubs of it somewhere thats for another project though I think i understand star grounding, its where everything goes to a single ground instead of it being daisy chained along to the ground? either way i'll be doing it tomorrow so i'll get back to you if its worked or not but i am confident i've got it sussed out now Thanks for the info
