For many guitarists, a Strat equipped with a bridge-position humbucker and two single-coils (HSS) offers the ultimate in sonic flexibility. If you have a guitar configured this way with a 5-way switch, there’s a way to make it even more versatile without adding any additional switches or hardware.

Project overview. We’re going to rewire the 5-way switch to coil-tap the humbucker in position 2. (Note: We’re using the usual numbering scheme that identifies the solo bridge pickup as “position 1” and the solo neck pickup as “position 5.”) You still get the fat, full humbucker sound in position 1, but in position 2, the humbucker goes into single-coil mode. Wired this way, position 2 offers a combination of middle and bridge single-coils, and you get much closer to that classic, clucky middle-plus-bridge combination Strat players love. One complaint about an HSS Strat is that in position 2, the humbucker sonically overwhelms the middle pickup. This coil-tap mod goes a long way toward eliminating that problem.

The two tone controls continue to function as normal, operating independently on the neck and middle pickups, and you get an expanded tonal palette consisting of five distinct sounds: solo neck or middle single-coils, two combined single-coil settings (neck-plus-middle or middle-plus-bridge), and, of course, the full-throttle solo bridge humbucker.

I recently did this mod on a HSS Strat loaded with a PRS Tremonti bridge humbucker, two stock Fender single-coil pickups, and a standard CRL 5-way blade switch. I’ll use the Tremonti to explain the mod, although the color of its wires may differ from those in your humbucker. Also, some switches work differently from the typical Fender 5-way we’re showing in these diagrams. That said, the essential concept remains the same, so with a little ingenuity you can apply this mod to most humbucker-equipped Strats or Strat-style guitars.

Tools and materials. To complete this mod, you need a 30- or 40-watt soldering iron with a small tip, a roll of .032" diameter 60/40 rosin core solder, some stranded 22-gauge cloth-covered wire, a 5" curved hemostat clamp (preferably with rubber-coated handles to protect your fingers from heat), and a medium Phillips screwdriver.

Tip: Never use a soldering gun around an electric guitar—it can damage your pickup magnets.

Getting started. First, take off the strings and detach the pickguard. Stash the screws in a safe place. Place a small towel or cloth on your guitar to protect the finish and then turn the pickguard over, being careful not to tug on any wires.

Next, check out Image 1, which shows how a standard Strat 5-way switch is wired. After familiarizing yourself with this diagram, correlate it to your 5-way switch.

Okay, it’s time to detach a few wires from that switch. Unsolder and remove the jumper wire that connects both sides of the blade switch so they operate together. Removing the jumper lets us use each side of the switch independently.

But wait! We’ll also unsolder the output wire from the lug marked “output to volume.” (This wire connects the 5-way switch to the input lug of the volume pot. Leave this wire soldered to the volume pot.) Later, you’ll re-solder the disconnected end to the opposite side of the switch. Because this output wire shares a switch lug with one end of the jumper, you might be able to unsolder both at the same time.

Once you’ve detached the jumper and output wires from the switch, unsolder the two tone-control wires from it. (Don’t remove the wires from the tone pots.) As with the volume pot wire, you’ll soon re-solder the two tone control wires to the other side of the switch.
