Guitar nuts.com t-riffic question.

(dead link now pointing to fake site disabled) www.guitarnuts.com/wiring/triffic/index.php

I'm attempting to emulate the t-riffic pickup selection option on my tele; but i'm using a rotary switch.

The 5 position 4 pole version from stewmac.

I'm struggling however to figure out which jack in this picture connects to which.
(dead link to image disabled) .guitarnuts.com/wiring/triffic/trifficsch.gif

Meaning, is A the same position as the leftmost jack on pole 1? or the rightmost?

In this schematic is it (with the numbers being switch positions):

Pole 1: Pole 2:
12345 12345

Pole 3: Pole 4:
12345 12345


or:


Pole 1: Pole 2:
54321 12345

Pole 3: Pole 4:
54321 12345


if that doesn't make sense i'll try to rephrase it.

I know which jacks are at the same position on my rotary switch, just not on that diagram of the yamaha switch.

Chris,

Hi, and welcome to the forums!

The proper answer to your question is "C" - none of the above.

Technically speaking, that wiring diagram is ker-flooey™ (ChrisK, 2006). Unless Yamaha is doing something strange inside of that casing, then I'd really want to think twice about blindly following that particular diagram.

The problem arises when you look at the diagram for a moment, as you compare it to the truth table (the chart that tell us how the pickups are connected for each switch position). Since the Neck pickup is supposed to be off in pos 5, and since we can see that Neck plus is going to ground on Pole 3 in the far left position, that must be pos 5, right? Q.E.D.

Looking at what should now be labeled as positions 1 and 3 also yields nice predictable results, but the remaining two, oh boy. I won't get into it now, but let it be known that I'm not comfortable with what I see here, even with all due respect for JohnA.

For my money, I'd say that the numbers run right-to-left, at least for 60% of the time.

p.s. No jacks were used in the making of this post! (But some switch terminals, now that's a different story. )

Quantum electrodynamics? Sorry, offtopic. But as ontopic I'd say that you can figure out the role of the lugs by using the following double wafer (superswitch) -diagram on the same page.

Just keep writing down which wire goest to where... comparing yamaha and supersw -diagrams.. and then draw the diagram again for the rotary switch.. complicated, but should work.... take it as a challenge... Here's the link to stewie for more info about yamaha-switch... not sure if it helps any, but maybe it can.

Good luck!

I'll assume you're being T.I.C. about that. For anyone who doesn't know:

Q.E.D. is an abbreviation of the Latin phrase "quod erat demonstrandum" (literally, "which was to be demonstrated"). In simple terms, the use of this Latin phrase is to indicate that something has been definitively proven. (from Wikipedia)

Dark, the diagram you posted will be a much better choice for translating to a rotary switch. In fact, a superswitch really is just a rotary switch at heart, operated by a lever.

The lugs marked "c" in the diagram won't necessarily be positioned exactly the same as in the diagram. But it won't be hard to figure it out, either.

[DarKnight]

Yes Unk you're right... There is no point to translate from lever switch to another when one can translate the diagram straight for rotary...

Cheers
Dark

DarK,

Thanks for that link..... I did a short google for such, but found nothing usable, sorry to say.

The Stew-Mac diagram says that the terminals of the Yahama plastic switch are numbered from the center outwards. That strikes me as really strange, given the mechanical motion you and unk agreed upon, up above. However, there are other switches on the market that purposely distort the layout away from a purely mechanical 1 to 1 terminal placement. Why, I don't know, nor do I truly care, I need only know that they exist, and that I avoid them like the plague. Why complicate something that works just as well, if not better, when it's at its simplest possible incarnation?

Still and all, that means that the Yahama switch's wiring diagram is correct, in so far as I can tell. However, when it's "translated" to the Allparts switch, a few things go south.

Correct me if I'm wrong, but the truth table says that position 3 should be just as the normal Telecaster wires the two pickups, they're in parallel, right? So looking at the diagram, I see that Pole 1, pos 3 is jumpered to Pole 2, pos 3. That's Bridge plus going to Neck minus, no? Not much chance of the two pups being in parallel, is there.

In my estimation, positions 1, 4 and 5 are good, positions 2 and 3 should have their wiring reversed on Poles 1 and 2.

Chris, this looks to be a good setup, it should be useful for you.

HTH

Thanks for bringing this thread to our attention swingarm . Several years ago John Atchley left his Guitarnuts site dormant and eventually the URL was grabbed by someone who now uses it to redirect. It's useless. We have a few saved pages in the Custom Pages links but most of his wonderful work has evaporated.

I edited the OP and disabled the links.

swingarm,


But you do get the highest award for "Resurrection Of The Longest Dormant Thread"! 11 years and 38 days, that's a record for The NutzHouse, you can bet on that!

But to get back on-topic, did you have a specific question about the T-riffic circuit?  We might be able to help, the concept around it is not entirely dead to us.

Seems like it, but I'm not so sure.



*puts a quarter on the table*



Are you a betting man, sumgai?

[sumgai]

Before I lay out any sheckels, let's determine a ground rule or two....

Are we talking about raw numbers, or are we adjusting for time? I ask because I think the previous record was chuck , resurrecting a 5 year old thread in 2010.  Adjusted, that's going to be hard to beat, but in raw terms, swingarm gets the kewpie doll.  Consider:

chuck > 2005 to 2010 = 100% of total time board has existed (he missed the total time by less than a month, but that's neglibile)

swingarm > 2007 to 2018 = 11/13 (span / existance) = 85% of total time board has existed

What's the ruling here? Or have I managed to forget some other member's contribution to this question?

sumgai

p.s. Edited to add: I see that you're plopping down a pre-Johnson quarter.  That's not exactly  $0.25 these days, is it.  What do I have to put out to match it's value?

[reTrEaD]

Raw numbers will be fine.

You can match the quarter with face values, ie: another quarter of any year you choose.
Or a nice shiny Admin badge if you have an extra one laying around somewhere.
I figure it's probably worth two bits.

[sumgai]

Well, we're fresh out of badges, as the term is used by ProBoards.... will you accept a promotion to the Administrators Group instead? I hope so, b/c I just did that very act!   (You'll have to go into your profile/settings tab, and select which group you want to appear on your mini-profile.)


And FWIW, you and I both deserve a "gumbo" award for tag-teaming this thread's derailment.   (Sorry, chriscrob.)

Look out folks, there's another Sheriff in town!

So I guess if we need to admonish someone for necroposting the duties will fall on Sumgai or Newey. In my case they could say - in pari delicto.

[JohnH]

I did a bit of research on the t-riffic, which seems to have been a 5-sound Tele design using a superswitch? I remember reading it but not the details.

Im sure we could reinvent that, but I also found this from deaf eddie:

Now I'll have to do the maths and look for the exact dates and times in order to determine who gets the Gold Star. Sigh, and here I thought an Admin's job was gonna be easy.

Anything that requires me to count past ten is not good. I don't like to take my shoes off. And if the count gets to 21, that's really not good.

The deaf eddie thing is plenty good. But I reckon a variant that replaces the Series OoP with Parallel HOoP would be a popular choice too. JMO.

Yes. It used the Yamaha switch because a Superswitch won't fit in a Tele control cavity without some modification to the guitar. Since these older posts, technology has come to the rescue, in the form of a new "narrow Superswitch" which fits a tele without modifications.

So, it looks like:

1) We can't find the original diagram, and

2) Nobody remembers the original scheme well enough to recreate it

swingarm, we're then left with reverse-engineering it. You have 2 of the requisite switches. If you post the switch logic for the Yamaha switch (a multimeter or simple continuity tester can be used to suss this out), and if you post a description of what the various switch positions did on your old version (what we call a "truth table"), we should be able to reverse-engineer a diagram.

[swingarm]

Thanks for posting that JohnH! And thanks to all you other fellas for the feedback

[swingarm]

here ara a few pics two from an old pic of the guitar I no longer have and one of the yamaha switch from an ebay auction (actually that 5 way switch looks incorrect) I'm away from home right now, so i cant post the bare switch.  
  

[swingarm]

Comparing the pic JohnH posted and my old pic it does not appear to be the same scheme.

Id expect its a bit different, designed by somebody else. But does it do the same functions? if so, then it could be equivalent.
