Could someone check this diagram please?

Hi there,







Completely new to guitar wiring. I did some research and now it's about to happen...



I refurbished my old guitar and want to change the wiring too.



I came up with this idea (it's not new, i'm sure)







3 humbuckers



3 DPDT switches for split/serial/parallel



3 concentric pots for volume/tone with a bleed circuit in



3 way switch for neck/all/bridge







Could someone please check this diagram and comment please?



The part which I'm not very certain of is the 'ALL' position of the 3way switch.







I'd like to have it 'ALL' to be able to mix different sounds together there (adapting volume, DPDT, tone of the individual PU's)







Thanks a lot already!

There doesn’t seem to be a signal ground for any of the pickups, and the way you’ve got the 3-way wired, you’ll have the middle always on. You do have the V pots wired “backwards”, so should be able to just turn that middle pickup all the way down when you don’t want it involved, though that will make it just slightly less convenient getting between certain settings. Course it also means there’s no truly silent off position as even turning down all three Vs leaves the jack hanging in the EM/RF wind. If you’re good with that, then just connect your pickup grounds properly and (I think) it’ll work.

Edit - actually no, I’m sorry the T pots aren’t quite right either as they’re not actually connected to the signal hot. Right now it just a capacitor hanging off ground not doing anything. I think (??) jumper from the middle of the V to the left hand lug of the T, though I guess which lug of the V you come off of is a 50s/modern question.

eroma3803, it seems that you’ve changed your diagram without letting us know.

When a person makes diagram mistakes, and then a smart guy like ashcatlt comes by and helps, it’s great, for me at least, to be able to find the mistakes in the diagram. Helps learning. Guaranteed, we all make mistakes; so it’s pointless covering them up.


If you want to remove your old diagram, please write a note during your edit so people phone browsers like me can understand that your diagram has been edited.


And, maybe it hasn’t been edited; sry if that’s so. (My extreme lack of knowledge my be evident now... oh well. )

Err...unless they’ve changed it back, I don’t think so. All the issues I mentioned are still there, and usually a post will tell us when it’s been edited, but I don’t see that here. Are you seeing something different?

Oooh, ok I must have been wrong.

Each pickup has a blue ground wire, and there is a red wire from the middle of the right-hand side of the v-type thing, but it IS connected to the right lug of the middle pot. You did say left side.

(Maybe your cached diagram is displaying if it is different from my description... refresh?)

It seems that the “edit” message doesn’t ever appear on my phone’s Firefox, so I’m sorry for my mistake. (Haven’t looked at this post on my CPU.)

I interpret that as a frame/shield wire. One of the four signal wires has to hit ground also. If that connection is made internal to the pickup, then the "restacking" that happens to make the one pickup split to a different coil ain't gonna work.

and there is a red wire from the middle of the right-hand side of the v-type thing, but it IS connected to the right lug of the middle pot.

I abbreviated Volume as V and Tone as T. By "v-type thing" I think you mean the switch. That's the common of that switch, connected directly to the output jack, and the output of middle pickup's volume control is always connected to it. None of the tone pots are connected to anything useful.
