Trouble Understanding DPDT Diagrams with CTS Push Pull (Grounding Question too)

[Kayxero]

Original Post:

So Im buying a Strat sized humbucker for a Bronco bass and learning to wire and solder up everything myself. Ill first practice soldering and desoldering from the old electronics.

Once I practice for a night or two, I plan to use 1 CTS pot and another CTS Push Pull pot for my 1 humbucker, 1 volume, 1 tone coil split configuration. Im just having trouble figuring out wiring and grounding....especially since Seymour Duncan diagram dont have numbers next to each of the solder points of the push pull pot (remember Im new to this).

So I want to ask two things:

1. How would I wire up a 1hum, 1 V, 1T Push Pull using a CTS Push pull pot and a standard CTS pot.

2. Regarding grounding....where would I solder to ground the CTS Push Pull pot? I've read some forum members even say its better for the unitiated newbies like me not to trying soldering to the back of pots (caution about ruining pots). Could I ground each of my pots with a different wire connecting to my copper shielded cavity? What about star grounding it?

Thanks A lot.

UPDATE:

Ive decided to stick with traditional DPDT pots like Alpha or Bourns. The more I read about the CTS push-pulls, the more I was turned off. Especially since i might want to rewire things in the future....and that doesnt seem so easy with the tiny, close together eyelets on the CTS push-pull pots. Desoldering in such a small area looks like a pain.

I think I may try and wire up a single humbucker, 1 vol push pull series parallel, 1 tone push pull coil split. What do you think? I never use 1 pickup basses, so I need to give myself some fun tonal options to try.

Does this work for you? The Push pull does series/parallel which would be my choice there.

This would be for South coil split / series

It shows you how to ground. Then all the grounds need to connect to the non hot output

I will be using a CTS Push Pull...and this diagram does not have the solder points numbered...so Im still a bit lost.

A CTS push pot uses a different layout with eyelets....and is a change to the typical bornes and Alpha push pots.

Hmmm I think I understand this now. Could someone verify this picture edit I made? The numberings arent usually on Seymour Duncan wiring diagrams...thats why I was originally confused. I wasnt sure which way was rightside up without the numberings, so I added the CTS diagram and then drew them in. Does this look right?

Im assuming if I wire this up the same way as an Alpha pot, but to the corresponding CTS eyelets...I should be alright?

Hey Kay. Welcome to the forum. It's late, but I'll draw you up something tomorrow, with the proper designations. One of the things I've learned by using those new style CTS push-pulls is that you want to be sure you know what you want, (wiring-wise), the first time. They're a bear to try and unsolder. But the series/parallel option is a good choice. Just did one of my own that way tonight.

Stay tuna-ed.

Its ok Artie. No need. Ive decided to stick with traditional DPDT pots like Alpha or Bourns. The more I read about the CTS push-pulls, the more I was turned off.

Cool. The one advantage these have is the low profile. I just discovered that a "normal" sized push-pull doesn't fit the cavity of my Peavey Rockmaster. Had it all wired up before I realized that. Test first.

Last simple question. When Im looking at Seymor Duncan diagrams the knob isnt shown. Do the diagrams assumed pointing the knobs upward on the DPDT pots? I just want to make sure I know the orientation of the instructions.

Re: Trouble Understanding DPDT Diagrams with CTS Push Pull (Grounding Question too)

Typically, they show the switch mounted to a pot. The side closest to the pot is the "up" or pulled position. If they don't show the pot, up is usually pulled. Ideally, you want to study the diagram so that you understand what is what by where the wires connect. Some people might want parallel, for example, to the default "down" position.
