Hi everybody! I am a new member of this forum, and this forum kicks butt! I wonder if sombody could help me with a specific wiring issue. I would like to add an S-1 switch to a standard Seymour Duncan 3miniHumbucker connection diagram, see link below:
By adding this S-1 I would simply like to turn the humbuckers in parallel coil mode (every humbucker has two coils connected in series. By pressing the S-1, I would like to turn them into parallel connection). I am trying to find help on the net for about a month, I even emailed Seymour Duncan but no answer. It seems that it is very difficult to find out how is the S-1 wired. Could anybody give a helping hand , please?
(the circuit is using a special fender 4-pole 5-way switch, as well.)
Thanks ChrisK for your answer! Well, lets say that I would like to set only TWO Humbuckers in parallel mode (neck and bridge). In that case, Can I do this with the S-1? Could you or somebody else provide me with the diagram including the S-1 connections as well? Bare in mind that I am not very familiar with electronics. Maybe a Hand made drawing saved in jpeg format will be the best idea.
While the use of the S-1 for three humbuckers is problematic, so is its use with only two and the link that you first posted.
This link is ok in positions 1, 3, and 5, but the 2 and 4 positions are combining one coil from each pickup. This will get real interesting once you start putting both coils in parallel on both pickups.
Each pickup is wires as a series pair, with the middle having the coils reversed in order (not phase) to expedite the 2 and 4 position structure.
I'm hesitant to draw a wiring diagram since I would first have to convert it to a schematic (wiring diagrams as a representation of circuit function [as opposed to wire placement] give me an aneurysm). The fact is that there is a ways to go in discerning what parallel even means with that wiring diagram.
It's far, far easier for me to do a design (schematic) that does what you want (exact pickup/coil combinations) once, and then spawn its encapsulation into a specific wiring diagram (well, guide, since I don't see things as specific wiring implementations).
Well, ChrisK first of all I am very happy (and gratefull) that you are offering help to me. I was getting really disapointed that noone would even try to help in a lot of guitar related sites and forums. Thanx for that! Well, please provide me with what you feel is best for you and then I will try to ask some specific questions such as (where do i connect the Red colored wire from the neck SD humbucker..) Do you think that things whould work that way?
(Now, didn't I make it real easy for you to post exactly what you wanted?)
Heck, it'll save me time................
On the neck and bridge wiring, the BLACK goes to the super switch as a pickup signal hot. The GREEN goes to signal ground. The RED and WHITE are tied together (internal coils are in series) and go to another pole on the super switch where they are shorted to signal ground to effect the combo's with the middle pickup.
For an (not necessarily every) S-1 switch pin out, look at my Electronics Templatespost. This is/was accurate for my first AmDlxS-1Strat that I got back in '04.
The little arrows indicate the internal connections in play when the knob is UP. The terminals that the arrows are coming FROM are the pole commons, and the terminals that they are pointing TO are the what the commons are currently connecting to. The terminals with no arrows either way are just the ones that the arrows will be pointing/connecting to when the knob is DOWN.
(I've added this text since, on several occasions, the concept has been missed or overlooked by some.)
I will describe the S-1 positions as "UP" and "DOWN".
So, we need two SPDT poles to effect switching per pickup.
Pole ONE will have the neck WHITE wire going to its common. In UP, it should switch to where it is hard wired now on the super switch, and in DOWN it should switch to the GREEN neck wire connection to signal ground.
Pole TWO will have the neck RED wire going to its common. In UP, it should switch to where it is hard wired now on the super switch, and in DOWN it should switch to the BLACK neck wire connection to pickup signal hot.
Pole THREE will have the bridge WHITE wire going to its common. In UP, it should switch to where it is hard wired now on the super switch, and in DOWN it should switch to the GREEN bridge wire connection to signal ground.
Pole FOUR will have the bridge RED wire going to its common. In UP, it should switch to where it is hard wired now on the super switch, and in DOWN it should switch to the BLACK bridge wire connection to pickup signal hot.
All we really did was build the standard series/parallel "switching module" into the existing design. This takes one DPDT switch per pickup. We just combined two DPDT switches into a 4PDT switch. One could just as easily used two separate DPDT switches (such as a push pull pot) to effect the same thing.
I have purposely not done a specific wiring diagram for just this instance since the concepts are universal and translatable to many wiring instances.
We just embedded a couple instances of a wiring module (shored up an existing design).
Things may be different now in S-1 switching, or on the one that you get. One should ALWAYS measure and document all components used for WHEN they have to support their own designs....
