Ways of aranging a control curcuit.

nipplepie · #1 12-31-2009, 12:46 PM

I've looked at two diagrams of bass precision pickups connected to 2 different curcuits of Volume, Tone and the input Jack.
What's the best way to connect one up?
Or which variation gives what sound?
Im not askin about the pick ups, I just want to know how to arange my Volume and Tone controls.

Please provide a diagram (Simple as on Paint will help me a lot)

Why don't you post the two diagrams you saw.

I'm guessing that you probably just saw two versions of the same wiring.
For example, on one, the capacitor connected to the center terminal of the tone pot, and on the other, it connected to the third terminal instead, with the signal on the center terminal.

Or maybe the capacitor was grounded to the back of the tone pot on one, and the third terminal of the volume pot on the other.

It's usually best to wire control circuits before the OUTPUT jack.

And yes, that's an output, not an input!

Yeah sorry forgot to post the diagrams.
Im experimenting with my 1st ever starter bass and this is the diagram for the new pickups I got for it.

But the curcuit on my control plate I have is this.

I tried re sketchin it to see if they are indeed the same curcuit but they are not.
Should I rearange my cicruit to the on on the pickup diagram? Or what other options are there? Does the ciruit matter in terms of sound, frequencies, tone...im a noob.

That sketch makes absolutely no sense.
Just wire it the way the Seymour Duncan diagram shows. That is the traditional way to wire a Precision bass.

Yeah that's what I was thinking to do.
But still one question is unanswered.
Do different wiring circuits effect the sound?
Or is there really just 1 and im a bit stupid.

What is the other method of wiring that you are comparing to?

There are pretty much only two things that you could do with P bass wiring:

You could switch terminals one and two of the volume pot, as it's done on a Jazz bass, but then the volume control wouldn't roll off as smoothly and give you a lot more high end loss, as the load would be varied against the pickup rather than the output.

Or, the other thing would be to place the tone control after the volume. This would mean that the volume control comes before the tone control rather than after.

And it makes absolutely no difference soundwise. We're dealing with AC currents in a passive circuit, electrons flow both ways.

You could wire the tone control (going by the SD diagram) off the output of the volume, and it would change the tone slightly. Mainly it changes the way the taper of the pots roll off, rather than change the tone drastically.

Yo, I connected the circuit and it works fine with the pickups. Now I need to connect a kill switch (ON/OFF) to the circuit to turn off the volume (circuit) within a switch. Where should I connect it?

slyjoe · #12 01-03-2010, 08:19 AM

You just need a switch that shorts the tip to the sleeve at the jack.

nipplepie · #13 01-03-2010, 08:28 AM

Could you direct me in terms of the duncan pick up diagram.

slyjoe · #14 01-03-2010, 09:26 AM

It's pretty simple - one wire from the tip, one wire from the sleeve of the output jack. Each wire goes to a switch as shown in this thread:

please help me with my On/Off switch

nipplepie · #15 01-03-2010, 05:42 PM

I did in serius which doesn't work. You should of said in parallel circuit, that's what works, and I think that's what you probably ment.
Yeah works fine

soo good P:
