Jazz Bass 1T, 1V, 3Way Selector + Series Parallel Help!

Sure it does.

Your switch is a four-position switch, right? Then yours has three poles, each with four positions. Just use two-thirds of your switch, and ignore the third pole.

Thank you but the only diagram I see there doesn’t match the switch I have. That’s the problem.

You have a 3p4t switch just figure out what lugs go to which common (the three lugs in the middle) and just use two of the poles.

Oh ok I think I see now. Sorry I’m not an expert at this.

Is this what you mean? Use the blue circle ones like shown in the diagram and ignore the red?

 

[ctmullins]

Yep, you got it!

Awesome, thanks a lot. I appreciate your patience. I am still learning this stuff lol.

 

[ctmullins]

Sure thing. Nobody’s born knowing this stuff. Happy to help.

Verify with a multimeter but yeah that should work.

Yeah I did just that because I was curious. I discovered it’s shifted a bit. The picture below is the actual configuration.

This was a good exercise though. I now have a much better understanding of how these work. Thanks again.

True; I always have to use a meter to verify which terminals go with which commons….

Sure. A four-conductor humbucker is two single-coils; they’re just mounted really close together.

That's what I figured but I just wanted to verify. Thanks!

Hi all. I need to revive this thread as I'm trying to hook up two humbuckers in my EB bass using the diagram previously posted and it's not working correctly. Some assistance would be awesome. I'll outline each issue one by one.



- The first and most obvious issue is that the wiring is backwards from the diagram. Position 4 is the neck and 1 is the bridge, which is the opposite of how it is on the diagram. No idea how that happened.

- Position 1 is the bridge, which seems to work, except for an awful buzzing sounded if I'm not touching the strings, like there's a grounding problem or something. And the neck pickup makes an awful noise when I touch/tap it.

- Position 2 seems to work ok. I think it's both pickups in parallel from the sound of it. No unwanted noise.

- Position 3 doesn't work at all. Nothing except for a weak sound that's very low. I guess this is supposed to be both pickups in series but's it's clearly not working right.

- Position 4 seems to be the neck. Like position 2, this one also seems ok.


I've checked and double checked everything. I had a blend knob hooked up before and everything was fine. So I don't know what to do. Any help would be greatly appreciated because currently I'm at a loss.

Oh also, I found this other diagram that seems to be labeled the same. Except the wiring is completely different from the one already in this thread that I've been trying to use. Any thoughts? Should I try this one instead? Thanks in advance.
