![]() It can be helpful to think of a guitar wiring diagram like a map that shows you how all the pieces fit together. Understanding the Basics of Guitar Wiring DiagramsĪt its core, a guitar wiring diagram is simply a visual representation of how the different components of your guitar’s wiring are connected. We’ll explain how it works, as well as some of its possible benefits and drawbacks. This simple wiring setup is often used in guitars that have one humbucker pickup and a single volume knob. In this article we will take a look at guitar wiring diagram 1 humbucker volume. It’s especially important for those who plan to modify or upgrade the electronics, for example making changes in the pickup wiring configuration. Here’s a video demonstrating the sounds available from the P-Rails.Guitar Wiring Diagram 1 Humbucker Volume ExplainedĪ guitar wiring diagram is usually an essential step for a guitarist to understand the electrical circuitry of their own instrument. Next time we’ll be looking at the last kind of toggle switch and seeing what kind of options it gives us. In that pickup, the switch we have wired here allows us to select between the P-Rails’ three main modes: P90, single-coil rail, or full humbucker.īecause we have only used one of the two throws on the switch, we could use the other three contacts with another humbucker to control two humbuckers in the same way with one switch. This opens up some slightly different tones in a normal humbucker, but with a P-Rails it really comes into its own. So this switch gives us the option between both coils active, or either of the coils in isolation. What this does is equalize the voltage between the start and end of the slug coil – meaning that now we have an active screw coil and an inactive slug coil. However, when the switch is in the “down” position, you’ll see that those two wires are connected to the hot output of the pickup. Note that of course the green and bare wires from the pickup can be grounded anywhere – but given that all the other wires from the pickup are going to the switch, it’s convenient to bring those two in here as well. This gives us the same coil split we achieved with a simple toggle switch in the last article – giving us the slug coil active and the screw coil bypassed. When the switch is in the “up” position, you’ll see that these two wires will be grounded. When the switch is in the middle position, these wires will not be connected to anything else, so the pickup will act in full humbucker mode. We’ve taken the red and white wires from the humbucker and connected them to the center terminal on one of the throws of the switch. A good example of use for this switch would be to control which coils are active in a four-conductor humbucker. Therefore, this switch is called an on-off-on switch. You can see that in the middle, no connections are made at all, while on the two extremes of the switch, the connections are made in the same way as an on-on switch. The connections made with the switch in each position look like this: The toggle switch stops in the middle to give us the extra position. It’s not available as a push/pull pot, only as a toggle switch. You can use it as a simple on/off switch by only using two of the poles, or you can use more connections to create more complex switching systems. It’s also the most commonly-used type of mini toggle switch. This is the type of switch built into push/pull pots. This type is called an “on-on” switch, because a connection is made in both of these positions. It’s a double-pole, double-throw switch, and it has two positions. The switch we looked at last time looks like this: This time around, we’re going to look at some new types of switch, and see how we can use those to access even more tones from a humbucker. In the last two articles we looked at switches, and then four-conductor humbuckers and some things you can do with them. ![]()
