Thread: Tone pot wiring

I had a similar problem which turned out to be a disconnected earth on my pot. Check all your earth connections with a circuit tester or multimeter. Maybe take a pic of the control cavity and someone might be able to give some suggestions with the wiring?
Good luck,

peter

Haven't tried the multimeter yet but i will do later. The buzzing gets quieter when i touch the metal of any pots so i know it's a ground issue. Here's a picture.

Does the third lug on the pot make a solid connection to the solder on the back of the pot? And are you confident you've got a solid ground connection to the bridge?

They'd be my first ports of call. But I agree that some pics might help.

You dont ever earth the third lug of a tone pot.

Replace the pot, Ive had some with the same symptoms, which ended up being faulty pots. It happens.

Why two caps??

might i suggest the wiring of the tone control as is done here

Oops ... I rushed in thinking of a volume pot not tone ... which now makes me wonder about why there is wiring shown from that lug?

Double check yourself against the wiring diagram attached by R3R ... you've got to love Seymour Duncan wiring diagrams for clarity. And if all that is correct, then Perry's advice on the pot is probably it.

I've decided i was just driving it too hard, and like most things when the amp is high and the volume of two humbuckers is high it distorts. I've turned it down and it sounds fine.

I got my wiring from the Seymour Duncan site;

And the 2 caps are 2x .22nf ceramic caps......they didn't have any .47's at the electronics store, so in parallel they add up.

Thanks for the input though.

Looking at the drawing of you tone pot pinout i noticed you dont have an output connected i presume this is an oversighe in your representation. Anyhooooo i have ammended your pic to have an output connection if the guitar dont have on it will be quiet. LOL

nope, thats wrong. The red wire is both the source, and output. There is no need for the green wire, in fact it wont even work.

Richard,

You do not need an output for a tone pot, This is only for a volume pot. The tone pot is just there to "bleed" off frequencys which is varied by the capacitors and the resitance of the pot (which is the variable component).

Cheers,

Peter

Yeah red is coming from the 3-way switch and going to the hot tip of the jack. Already complete though so you guy don't have to worry
