Basically can I do series/parallel and dual coil tap by replacing my 2 tone pots with push-pull pots?
I know I can do the dual coil tap with 1 push-pull, and I can do dual-coil tap and phase with 2 push-pulls but I can't find anything on dual-coil tap and series/parallel.
* Note: Always plan the project then order the parts. Especially if you have no idea what you are doing like me. Other wise you are left asking stupid questions on a forum.....

Especially if you have no idea what you are doing like me. Other wise you are left asking stupid questions on a forum..... We need more info. What kind of guitar do you have? What kind of pickup setup? SSS? SSH? HSH? HxH? Series/Parallel microswitching or macroswitching? (IOW, series/parallel between pickup coils, or between the pickups themselves?) Now, the usual answer to any question you ask here is "yes", assuming money is not a factor and you don't mind either some tricky wiring or some tricky switching, or both. Of course, that said, simpliest is best, and the easier you keep things the better. Now, assuming that you want to do series/parallel between two pickups, a la the Jimmy Page LP Mod, you can use this. Now, that covers HxH. If you want something along the lines of SSS, SSH, or HSH, then the UUSS would work for you. Other than this, it would help if we had more info. Chesh

I would recommend a 4-way switch and having one P/P switch per pickup. I know that would require some pickguard modification but it is the easiest way to go about this. With a 4-way switch you can go from Bridge/B-N Parellel/B-N Series/Neck. Many tele's have these.
In the slightly paraphrased words of someone else on this forum (call me out if you know its you because I forgot). The only stupid questions, young grasshopper, are the questions that go unasked.

ok I tried to not be long winded int he first post and in turn left out most of the pertinant info. SO here we go.
2 Humbucker guitar both are 4 wire. I have 4 pots. The two tone(linear) pots are push pull. 3-way switch. I dont want to order anymore parts because it takes forever to get any parts unless I want to pay a the guitar tech like $12 for a pot.
What basically I want to maximize the use of the 2 push and pulls without spending more money/time.
I want dual coil tap and was hoping for series/parallel switching where the push-pulls are the only non standard components. So is this going to be possible or is it going to be coil tap + something else?
Thanks again

So is this going to be possible or is it going to be coil tap + something else? First, never try to not be long-winded. Trust me, this isn't a board where you need worry about that. Second, as to the mod, no-brainer. Just do a Jimmy Page LP Mod, and you're gold: BTW, what's the bit about taking forever to get guitar parts. Where do you get them from!?! What are the other two pots?

The Jimmy Page mod suggested by Chesh is well tried and tested. But...
If you want coil-splitting and series/parallel within each pup (local series/parallel), the best way of doing it using what you've got is as follows:
One push/pull is a dual coil-split that gives outer coils only; The other push/pull is a dual coil-split that gives inner coils only;
The magic is that when both push/pulls are pulled out each pup is in parallel with itself (local parallel, microswitched parallel, take your terminological pick).
If you are interested in this I will try and find a moment to do a schematic. What kind of diagrams can you read?

Ok first all thanks for the replies. Yes the Jimmy Page mod looks awesome and I might have got 2 push pull audio pots added to my order which apparently hadn't shipped yet. I had originally ignored it because it used 4 push/pulls and I was trying to save money by only buying 2.(But it occurred to me who needs money when you have guitar). I guess I was originally looking at doing series/parallel between the pickups not locally. But if I don't get the other 2 push/pull pots I will be doing that mod so a schematic would be great. (Although I could pm you to save yourself from doing unnecessary work if I end up doing the JP mod.) I can read regular schematic but I would be lying if if said that guitarelectronics/Seymour Duncan pictorial version wasn't better for me. So whichever one is easier for you. As for taking so long to get guitar parts: Any US parcel service + Canada Customs = annoyingly long wait times. The latest package is coming from www.guitarpartscanada.com, which I thought would save me a lot of time but he is waiting to get some of my stuff from the States and surprise he has the same problem I do. But I do save money by ordering through him so its worth it. As for the other 2 pots they are CTS audio pots.

If you pm me you might not get a response as I rarely remember to check them and often don't login. But I glance at the boards here quite often to see what's going on so just post if you do want a pic.
You could do a slimmed down version of the Jimmy Page mod with just two push/pulls.
One would unify both the coil-splitters into a dual coil-split; The other would be the global series/parallel switch in the JP mod.
It might be possible to get a local parallel option on one pup as well as the above with just two push/pulls. I will have to have a think.
An even more ultimate version of the JP mod would use four push/pulls with two wired as I suggested earlier (to do Inside Coils, Outside Coils, and Local series/parallel) and the other two doing global series/parallel and reverse phase.

Second, whatever the case, wait for the two additional push/pulls. It will be well worth it. And, believe me, I'm someone who knows about waiting on getting mods done.

annoyingly long wait times = ~3weeks. I'm very impatient so when I get the urge to do a project 3 weeks is a long time. (kinda whiny, but it is very easy to take 2 months waiting for parts and the actual wiring takes an hour.)
But more importantly my last shipment was $22 shipping. So if I order 2 push-pull pots it is very easy to double the cost on shipping. So I tried to get the parts in Canada now its been 2 weeks without shipping it because he is waiting for stuff from the states. But its only 1 week once he ships it. So it works out the same with less shipping.

I remembered some previous discussions about the JP mod that may be relevant, and did a search. It is further down in this thread: guitarnuts2.proboards45.com/index.cgi?action=display&board=wiring&thread=1136554581&page=1The JP mod is one I have done, and for its objective of keeping things looking stock it really does a lot. There are some annoying things however: - In System Series, the vols are no longer independent, (and arn't fully independent in SysPara). The Vol becomes a master tone in SysSeri, and in that setting is where you need the mixing capabilities of 2 volumes the most.
- In SysSeries if you shove the 3 way to Bridge, you get nothing, you have to punch the PP back to SysPara to get the Bridge pup.
I belive John H solves the indepence issue with a 3PDT toggle (in another discussion I can't find). He also has a 3 PP adaptation of the JP mod in the thread. RW

The JP mod was first designed for JP back in the 70's when a Neck-on switch was the height of sophistication. It can certainly be improved.
Sorting out the independent volumes shouldn't be a problem if you base the design on ChrisK's series/parallel blender. There's probably a way to solve the dead spot in system series as well.
John's three pp version can also be expanded with an extra pp to give local parallel on each pup which might be nice.
I will find a moment to hack a picture. (Anything is better than honest labour in this heat).

I have posted an improved version of the Jimmy Page mod on the schematics board. It is in tradition schematic form because I'm not very good with MS Paint. Have a look and let me know if it is helpful.

Yes that is very helpful and that is what I will be doing because I *am* for sure recieving an extra 2 push/pull volume pots in my shipment.
Beautifully done btw, I really like it.
I'm going to draw out a layout for it and I would be very grateful if you could look it over for me.
Thanks for your all help, thectrian

Sure. If you post the layout on the same thread as teh schematic it will be helpful for everyone.
I always worry that my schematics are rather scrappy in comparison with the works of art produced by folk like ChrisK, so thanks for the compliment.
