Replacing the common 5-way pickup selector switch on a Strat with three individual on/ off switches is more or less a variation of the “7-sound Strat” mod we discussed in detail earlier. With three individual switches, it’s possible to dial in the bridge/neck pickups together in parallel (as you can do with any Telecaster) as well as all three pickups together in parallel. You can’t do this with the traditional Strat wiring and a 5-way switch. The easiest solution is to simply route the neck pickup via an additional toggle switch and you’re done (for further details please see my earlier column about this subject).
So why would someone replace the traditional 5-way switch on a Strat with on/off switches? There are several reasons: 1. with three switches in a row, it’s easier to visualize what pickups are selected; 2. it looks cool and will get some attention because it’s different; 3. with three push-pull or push-push pots for controls, it’s possible to build a pickguard without any switching controls on the surface (this will look even cooler on a beautifully grained wooden Strat pickguard) 4. three on/off switches are much cheaper than a 5-way switch, so it can be economical when building a new Strat pickguard from scratch; 5. it’s easier to do some special mods with this configuration, so you’ll often find this on heavily modified Strats.
In a nutshell, this is like cutting a 5-way switch into three equal pieces and connecting each pickup to one of the pieces. Electrically, it’s the same as having the 5-way switch, so it will have no influence on your tone. To start, you need three on/on SPDT toggle switches of your choice. You can also use on/on SPDT push switches, push-pull or push-push pots, or any other switching device of your choice. For this mod, I recommend you use a new pickguard without the routed slit for the typical 5-way switch. Such pickguards are available from many sources and will definately look better than drilling three new holes in addition to the (now unpopulated) slit. Naturally, you can use your stock pickguard and drill away. It’s your axe, and you have to like it!
As mentioned earlier, a beautiful wooden pickguard allows you to use three push-pull or push-push pots to switch pickups, so you won’t have anything on the surface besides the three knobs. This really looks cool and will definitely get your axe noticed. Some time ago, I had a customer who wanted three touch-sensitive switches underneath the pickguard, so he just had to tap a certain spot on the pickguard to dial in the desired pickup combination. This is also possible and could raise a few eyebrows. As always (in case you haven’t done it before), printing out the standard Stratocaster wiring and placing it on your workbench is a good way to start. This way, it’s much easier for you to see and understand the differences from the modded schematic.

Let’s Get Started
First of all, desolder all connections from the 5-way switch and take it off. Naturally, you don’t have to do this when you’re building a new pickguard from scratch. Decide what switching device you like best, and install it on the pickguard. Now connect everything as shown in the drawing below and you’re done. It’s very easy to do, and if you compare this wiring with a traditional one, using a 5-way switch, it’s very easy to see how these switches substitute for the function of the 5-way switch. Each toggle switch has an input (middle lug) to connect the pickup, and an output (bottom lug), to connect to the next switch, and finally to the input lug of the master volume pot—just the same as on the 5-way switch, but with individual switches. The upper lug of each switch is connected to ground. To make this connection easier, each of these lugs is connected together, and only one has an additional ground connection, to ground all three switches. This will save you from a cable mess on the pickguard. Alright, that’s it! It’s a simple mod, and you have only to decide if you want it or need it. Based on the number of requests I received, I assume a lot of players need it.
Stay tuned for more Strat mods coming in the months ahead. Until then... keep on modding!
