3-Way Humbucker Wiring Mod – More Tones for Your Trouble

Want to squeeze even more magic out of your Warman humbucker? One of the easiest – and most rewarding – upgrades you can make is adding a 3-position mini toggle switch. Think of it as giving your pickup a split personality… and then a third one for good measure.

Here’s what you get with the flick of a switch:

3 way humbucker wiring mod
  • Position 1 – Series Mode
    Both coils running in series for maximum beef, bite, and output. This is your humbucker’s “full English breakfast” setting – hearty and satisfying.
  • Position 2 – Single Coil Mode
    Switch to just one coil (coil 2, to be precise). Suddenly you’ve got that glassy single-coil sparkle on tap – lean, bright, and ready to cut through the mix.
  • Position 3 – Parallel Mode
    Both coils running in parallel. This gives you a punchy, hum-cancelling single-coil style tone – a bit like a P90 that’s been to finishing school.

Wiring It Up

The diagram (shown with the switch viewed from the underside) makes life simple. You’ll want to wire the switch in before sending the output to your pots or selector switch. Once the switch is in place, run the positive and negative leads onward to your controls.

A word of caution: the solder points and wires on these switches are small – really small. Think “trying to butter a crumpet with a fencing foil” small. So, take your time and keep your soldering neat to avoid any accidental shorts.

Why Bother?

Because it’s fun. And because it gives you a lot more usable tones from your guitar. Do the mod on both your neck and bridge humbuckers and you’ll unlock a whole new sonic playground. More punch, more sparkle, more character – all without buying a new guitar.

How to Make Your Humbucker Go Solo—Literally

Ever wish your humbucker could sometimes just be a single coil, like Clark Kent turning into Superman? Well, grab your soldering iron and a push–pull pot, because you’re about to unleash your pickup’s inner hero.

Step 1: Wiring the Humdinger (Humbucker, that is)
When everything’s in its classic, rock ’n’ roll setup (push the pot in), your humbucker is doing the two-coil tango—series style. Here’s the star-studded cast:

  • Black wire: coil 1 negative → grounded (back of the pot)
  • White wire: coil 1 positive
  • Red wire: coil 2 negative
  • Green wire: coil 2 positive → to the input of your volume pot
    Roll call: black → white → red → green. Two coils, one glorious roaring tone.

Step 2: Pull the Pot—Activate Single Coil Mode
Pull that knob up like you’re summoning a magic spell, and boom—coil 1 is muted (grounded out). This leaves only coil 2 (red to green) to do its solo thing. Quieter, brighter—like switching from a blockbuster action scene to an acoustic ballad.

Step 3: Return to Duo—Push the Pot Down
Push it back down, and the full humbucker harmony is restored. Two coils singing in series once more.

Why This Works (But Without the Nerd Speak)

Think of your humbucker as two siblings stacked in line. With everything pushed in, both are holding hands (wired in series)—strong and loud. Pull the pot, and you tell the first sibling to go hide (grounded). Only the second sibling plays—subtler and shinier.

Little Side Note for Accuracy (Because Tech Matters)

Fair warning: guitar lore loves to mix up ’coil tap’ and ’coil split’. Here’s the skinny:

  • Coil split (what you’re doing here) kills one coil of a humbucker, turning it into a single coil.
  • Coil tap (a different beast) involves using a partial winding of a coil to change its voice—mostly in single coils, and not what we’re doing.

Wiring Up Warman Single Coil Pickups

Most Warman single coil pickups keep things nice and simple. Just two wires to deal with – a negative (start/ground) and a positive (finish/hot). Compared to humbuckers with multiple wires, single coils are the wiring equivalent of making toast – quick, easy, and very little can go wrong.

  • Negative (ground) lead → connects to the guitar’s common ground circuit (usually the back of a pot).
  • Positive (hot) lead → connects either to your selector switch or directly to the input lug of your volume pot,. This depends on how your guitar’s control circuit is set up.

Wire Colours

  • If your pickup has two separate wires:
    • Black = negative (ground)
    • The other wire (various colours depending on position) = positive (hot)
  • If your pickup looks like it has only one wire, don’t panic! That’s actually a twin-cored cable:
    • Outer braid/shield = negative
    • Inner core = positive

That’s really all there is to it. Warman single coil pickups are among the easiest to wire up. You can check out our full range of upgrade models [here].

A Note on Phase Reversal Switches

If you’re fitting a phase reversal switch, there’s one extra step to consider:

Before you do, check that the coil’s negative isn’t already soldered to the baseplate. If it is, simply snip that link so the coil and baseplate are independently grounded.

If your pickup has a metal baseplate (like many P90s do), you’ll need to solder an extra ground wire from the baseplate to your guitar’s ground.

If you’ve just unwrapped your shiny new Warman humbucker and you’re staring at a handful of coloured wires thinking “what on earth do I do now?” — don’t panic. Grab your soldering iron, make yourself a brew, and let’s walk through it.

The Warman Humbucker Colour Code

  • Bare wire – This is the shield/earth. It always goes to ground. The usual spot is the back of a potentiometer (pot for short). Think of it as the pickup’s safety belt.

  • Black wire – Negative / start of the South coil.

  • White wire – Positive / finish / hot output of the South coil.

  • Red wire – Negative / finish of the North coil.

  • Green wire – Positive / start / hot output of the North coil.

Standard Humbucker Wiring (Series)

To wire the pickup in standard Warman humbucker mode (both coils in series):

  1. Solder black + bare wires to ground (back of a pot is perfect).

  2. The red and white wires are already soldered together. Leave them joined — they’re the “bridge” between coil 1 and coil 2. Tuck them safely away with insulation tape.  or heat-shrink so they don’t short out.

  3. The green wire is your hot output. Connect to either your pickup selector switch or straight to the input lug of the volume pot.  This depends on your guitar’s wiring style.

That’s It!

And there you have it — the Warman wiring colour code in all its glory. Nothing scary, no rocket science, just a bit of solder, some common sense, and the smug satisfaction of upgrading your guitar.

Now plug in, turn up, and give those coils the workout they deserve.
