MODULES

[UnklMickey]

hi all,

i don't really have the authority to make a command decision like this,

but i will anyway.


the purpose of this thread,

is for all the simple pieces or MODULES that one would use in designing or modifying a wiring scheme.

things like:

• series / parallel switch for 2 coils
  
  
• coil split switch
  
  
• series / split / parallel switch for 2 coils
  
  
• phase switch
  
  
• etc
  

each post should be for just one module, and appropriately labeled, with it's function.


and, as always, we thank you for your support.

Oh?!

I think the following close-up speaks for itself!

Blend Pot Coil Split


Red Rhodes (Peavey) Tone_Coil Split Pot


Series_Parallel Blend Pot w/ DPDT switch

[johan]

This is a great idea!

I did a few wirings like that, taking bits and pieces from here and there. I really really wanted something different then the humbucker split in M+B postition. It would allow more flexability and a library of these modules would be real handy in helping firsttimers out.

but then were immediately back to the meta question: how to do that in a way that makes this information easily accessible to those who need it.

the amount of time and effort some participants put in this board is truly amazing and not so common on message boards in general. it's a shame to let all this info go to waste. that also, I believe, why the schematic board was set up. and these are very much worth reading, but still...

they deserve a web page. basic 'modules' and wirings, series-parallel etc are all explained on several known webpages: John A's, Wolf's, JohnH's. Everything's not everywhere. John A's is quite complete I think, but why did he stop updating which leads me to ask.. the schems in the schem. section. why aren't these published on John Atchley's website?

Maybe a well structured links page or FAL (frequently asked links) will help us a long way.

Seymour Duncan has quite a few modules on the site (not complete wirings, but parts).. is that what you mean.

Strat series mod

Strat series split mod

Single Coil Phase Reversal mod

Johan,

my original vision for this thread was to provide a couple of functions.

one would be so that the donated modules could be cut and pasted, all or in part, to a design that a newbie, or intermediate level designer could use to create a drawing.

since the original work would be donated by our members, who understand the purpose, these new designers would not be guilty of "stealing" someone else's work. we run the risk of offending someone, or worse, if we don't have their permission to copy and alter their drawings.

newbies could do much of the design work on their own, without putting that burden on the "senior staff".

that would free the wiring gurus up so they could spend more time checking the final product.

this would also make it easier for our intermediate members to grab onto a question and assemble a composite for a true newbie.



the other part would be, that we would have locally available drawings, that we could grab the properties of, and paste into our posts, so we could be able to answer the "how it works" questions.


this is all experimental and i don't know if RandomHero approves.

but i thought i'd try it out.

worst case, he might remove it from schematics and put it in E & W.





i'm almost tempted to copy my links thread, and post it schematics, but i need to update it. it's about 6 months out of date.

if you're interested in bringing that up to date, and organizing it in a manner that makes it more usable, RandomHero will no doubt find it more valuable, and perhaps even create a "sticky" copy to post in an easy to find place, perhaps here in Schematics or in another sub-board or something.

but, no guarantees on that. his name is on the lease. i just hang out here, and fix dinner occasionally.

here's a little something you might find useful:

[UnklMickey]

above you find 4 possible ways to do series/parallel switching of 2 coils or 2 pickups.


version (a) is most commonly seen, it's okay but i think it could be better.

it requires the series path to go first through one of the two lower contacts, then through the other.


version (b) is a bit of silliness i put together. since the series path uses both lower contacts, in parallel, that should make it more reliable, right? BFD. save the extra wire.


version (c) is okay


i think version (d) should be the universally used method.

3 days worth of atta-boys for the first person who can send me a PM explaining why (d) is so "universal".
(any non-god, with the right answer within the first 2 days will get the K even if a god is first.)

regardless of when (or if) i get a correct answer, i'll post the reason Friday.

PLEASE DO NOT POST THE ANSWER ON THIS THREAD!

EDIT:

well even with a 2 day head-start, no one beat ChrisK to the punch on this one.

he was still the first one with the correct answer.






note that the only difference between the 2 circuits, is the switch itself.

the switch on the left: DPDT ON-ON-ON,

the switch on the right: DPDT ON-ON.

i thought i'd post another diagram.

although it could be used as a complete wiring system, i included this on the module thread.

it's more likely to be used (minus the tone and volume) as one portion of a much larger scheme.

i actually have posted something nearly identical to this, in an old thread, as a pictorial.

anyone recognize it, and what it does?

[pete12345]

Both switches down gives you both coils in parallel
Switch1 up gives you coil A only
Switch2 up gives you coil B only
Both switches up gives you both coils in series

It's a handy way to control 2 pickups with 2 DPDT switches. It could also be used to switch, for example a middle pickup with the switched combinations of neck and bridge.

EDIT 20130717: by newey:

The above link from ChrisK is broken, and there's no way to be sure to where the link led. But if memory serves, Chris was linking to this thread:

binary tree switching

Just a best-guess on my part, really.

Hi Newey,

In the above post from ChrisK (the one you edited), you state the you think that Chris linked to this thread:

www.guitarnuts2.proboards.com/post/27950

I like these kind of puzzles (minimal information), so I applied some Google-fu, and came up with this thread:

guitarnuts2.proboards.com/thread/1610/individual-on-off-switches

I the above thread, Chris uses the same URL as he did in his last post to this thread. Some more Googling and I came up with this thread:

guitarnuts2.proboards.com/thread/1344

Of course, I do not know if this is the correct thread either, but I'm sure that you would probably have a better sense of this than me.

Col-

Your approach to the puzzle is interesting. I guessed he was pointing to the binary tree thread because that was the answer to the question unk posed, and which pete12345 correctly answered. Both the threads you linked to deal with using switches (of various types) for parallel-off-series, but there are a number of "dead links" in those discussions, so who knows whether one of those led back to the binary tree as well.

I have used a two-binary-tree scheme on my 4-pickup "4caster" and it works well although it takes a bit of getting used to. With 4 pickups, two levels of binary tree (meaning 6 DPDTs) could have given me all series/parallel options, but lack of real estate in the cavity led me to use only the two binary trees (each tree governs two of the four pickups); the two "trees" are then combined only in parallel by a three-way toggle. So, it won't do all in series, or series combos of parallel pairs.
