help with 2 humbuckers with effects


Recommended Posts

Building this Peavey


Going to be putting two "single coil housing" humbuckers in the bridge position. So far the flow schematics I drew up are:


Switch 1 Position a) forces series through all 4 coils.

Switch 1 Position B) forces humbuckers in parallel

Potentiometer 1) bridge/neck balance

Switch 1 Position c) forces parallel mains


Switch 2 Position a) Bridge only

Switch 2 Position B) Bridge + Neck circuits in parallel

Switch 2 Position c) Neck only

Switch 3 Position a) single coil Tail-Bridge

Switch 3 Position B) Bridge coils in parallel

Switch 3 Position c) single coil Mid-Bridge

Switch 4 Position a) single coil Mid-Neck

Switch 4 Position B) Neck coils in parallel

Switch 4 Position c) single coil Head-Neck

Switch 5 position a) standard parallel

Switch 5 position B) tone sub-circuit [not finished obviously]

I was interested in putting individual phase changers in the parallel tone sub circuit but instead, I think in going to eliminate the tone sub circuit and put a phaser and fuzz inline of main signal.

I just wanted to make sure that I'm getting every thing correct.

Posting this here for reference

> Wiring and Tone> Wire colour codes explained

Standard format of wire colours on Warman Pickups.

As a general rule our humbucking pickups follow a standard format for "which colour wire does what" as explained below.

Bare wire. This is the overall earth wire an needs connecting to a common ground point, usually the back of one of the potentiometers.

Black wire. This is the start / negative wire of coil 1

White wire. This is the finish / positive wire of coil 1

Red wire. This is the start / negative of coil 2

Green wire. This is the finish / positive wire of coil 2

In some production runs and pickup models the green wire is replace with a yellow wire, but it is still the hot out of coil2.

Our 4 wire humbucking pickups come pre-wired with both coils running in series, which means the signal passes up the black wire, through coil 1, goes out of the white wire and into the red wire into coil 2, then finally out of the green wire. This is the pickup operating at its most powerful setting.

First: Welcome to the forum.

Secondly; Wow! That s lot of options and a lot of switches. Just so that I get it right; you mean that you are using two "hot rail" style (or similar) HB pickups in the place you usually put a single HB? I am very curious about how big difference you will have between, say the coil closest to the bridge compared to the coil closest to the neck. The distance isn't that huge. Anyway, looking forward to see (hear?) the end result

Yes that is correct and exactly why I was interested in installing a passive tone sub-circuit within the parallel circuit.

For example, if I filter all the but highs from the tail-bridge, all but the high-mids from the mid-bridge, all but the low-mids from the mid-neck, and all but the lows from the head-neck, It may make them cut through themselves interestingly.

As far as the actual wiring, I'm expecting the need of relays as I know of no existing switches that would facilitate this.

I would also be interested in fabricating my own hybrid switches (passing point/knife) similar to:

I'm confidant I could fabricate all but the two push/pull pots which would activate the parallel-tone sub-circuit and the effects sub-circuit.

I designed a 6 pole triple throw switch; which, when used in an array, could complete all but the single coil switching and parallel tone sub-circuit.

In this image, I have removed the tone sub-circuit and have left the single coil switching in schematic form with all coils live and in parallel. Keep in mind the switch is not designed for manufacture at this point, I'm just using it to help with wiring.

The body is a Matsumoku from another of my projects and does not reflect the actual routing, as you'll notice it's using standard humbuckers; again just to aid with wiring conceptualization.

The only other way I can imagine wiring this all is to use relays.

When installing the pickups, I will not be installing all of the wiring; I will use jumpers to a breadboard to test and verify data first.

After verifying all parameters and testing the switching, I can decide if there is significant difference between the single coil positions enough to warrant a full install.

Now, since I have no experience with guitar electronics specifically, it is my assumption that common ground (pickup housing/bridge/etc grounded to back of a pot) is wired to the sleeve connection of the 1/4"jack along with the ground from the coils themselves. Is there something I am completely missing?

been away a while busy, got everythign wired up in series for now; just no time for more in depth projects.

its now my daily carry, best i could have done im sure. for ~$60 bucks its hot

i also got some recording equipment for DI and a nice ass tube amp that ive got mic'd up to it as well. pretty sweet things going on.

im going to start shaping and mapping this week and should have raw by the end of the month get some compressed samples posted here and then get to some srs bsns before the year is up
