HSS Auto-Split
Most Strats use a middle pickup that is reverse-wound and reverse-polarity (RWRP) so that you get hum-canceling in positions 2 and 4. Add a humbucker into the bridge, and it's important that you split the humbucker in the 2 position, so that you combine only one of its coils with the middle pickup. This allows you to retain hum-canceling in this position, and it also most-closely approximates the tone of a Strat in the 2 position. You could add a switch of some type that would allow you to manually split the humbucker, but this would mean manipulating two switches. Most players prefer to let the 5-way switch perform this function automatically, so that position 1 is always the bridge humbucker, while position 2 is always the split humbucker combined with the middle.

What about pot values? Humbuckers are voiced with 500kΩ pots (the traditional Gibson value), while Strat pickups are voiced with 250kΩ pots (the traditional Fender value). A 500k volume pot will make the guitar a little brighter, so it's great with the humbucker, but can make the single coils a little over-bright. Conversely, a 250k pot can make the humbucker a little too dark or "wooly". With our HSS assemblies you don't have to compromise. We use a 500k volume pot so that the humbucker sounds right in position 1, but we add a resistor into the circuit in the other 4 positions, dropping the load to 250k, so that the other positions sound right. Hey, who wants to compromise where tone is concerned?

Finally, to make this wiring truly custom, we've used our ToneShaper narrow superswitch rather than the standard 5-way, so that we can customize the tone controls. The standard Strat switch assigns the tone controls to specific pickups, but the superswitch assigns them to specific switch positions, which allows for more granular control. We've assigned the lower tone control to position 1 only, and we've used Gibson-esque values for both the pot and the tone capacitor. This optimizes the tone controls for their respective positions: Gibson values for the "Gibson" position (position 1), and Fender values for the "Fender" positions (2/3/4/5).

I had a special wiring/pickup configuration that I needed, which wasn’t on the website. I spoke to a very knowledgeable associate, which without hesitation said he would send me an updated a wiring diagram, included it in my order. I expected maybe something hand drawn but the diagram was totally professional!! Thank you!

Fantastic HSS Kit and Support!

This is a great HSS kit! I was doing a pickup configuration I couldn't find wiring for, and while still a single coil, HSS configuration, I wanted a P-90 in the neck, and wanted the humbucker and P-90 to share the 500k tone pot. George entertained my silly questions and put me at ease. Guitar sounds great! I've already bought a second one of these kits, so I'm a fan!


First, off what a great kit with quality components. I like how you get your choice of wire. Perfect amount. CTS pots, OG superswitch are worth the price alone in my opinion. I had a two wire humbucker in my setup, which I wasn't aware before ordering. I wired everything according to the very well illustrated diagram included. Mine didn't work, but I called and talked to George and he was super helpful in talking me through what changes I needed to make. My old squier strat (first guitar) is born again with new life and sounds better than ever! I will be doing business with this company again. You will not be disappointed if you order anything from these guys

Great Kit

This will be the third HSS auto split with treble bleed network I have installed. Medium easy to do. Take your time and make it nice.

As Promised!

This is an absolute upgrade over the stock components in my guitar. They improved everything about it, so much so that I’m going deeper into the mods to get the most out of this change. So far, so good! 😃
