Edit killswitch guitar: the wiring

There's an effect, a sound, that when you hear it for the first time makes something click inside you. That rhythmic "cut and paste," that sudden silence that breaks the musical phrase and then restarts it with a burst of energy. I heard it live for the first time, on the guitar of a friend who played in a prog-metal band, and I said to myself: "I want this too!" Let's talk about killswitch guitar, a switch that, when pressed, instantly silences your six-string.
It's not stuff for electronics wizards, I assure you. You don't need an engineering degree or years of experience with a soldering iron. You just need to understand two or three basic things about the signal path in your guitar, have a little patience, and not be afraid to do some soldering. I, who have burned more potentiometers than I can remember and made crooked holes in a couple of bodies before learning, tell you that if I succeeded, you can do it too.

In this article I will not only explain to you as mount a muting switch, but also Why It works a certain way. We'll look at where to insert it into the circuit, what components you need, and how to avoid classic beginner mistakes (the ones I made, basically). The goal is to get you to the end with a solid understanding, not just a list of steps.
