The Difference Between NPN And PNP Transistors

September 20, 2024

Transistors come in a lot of different types, but in this article, I’m only going to be talking about bipolar junction transistors (BJTs). Specifically, I’m going to be talking about NPN transistors and how they’re different from PNP transistors. A transistor is a component that’s very commonly used in guitar pedals and other electronics. If […]





A simple diagram showing what a coupling capacitor sits in a circuit.

What Are Coupling Capacitors?

September 13, 2024

In guitar pedals and electronics in general, coupling capacitors are important to keep different parts of a circuit separate and to prevent DC power and other noise from moving from one sub-circuit to another. All in all, it’s quite simple, and that’s really the explanation… but if you want to know more, read on for […]

What Do Guitar Pedals Do?

September 10, 2024

It didn’t occur to me to write this article, but I noticed that people were coming to this site asking “what do guitar pedals do” and ending up on my how do guitar pedals work article, which doesn’t really answer the question. So I decided to answer the question in order to help! All of […]





Stripboard layout for a Green Giant effects pedal by Greer Amps.

Greer Amps Green Giant On Stripboard

August 28, 2024

https://www.youtube.com/watch?v=-muKTaGdx9E Here’s a kind of weird guitar pedal, but a fun build nonetheless and also a pretty simple guitar pedal build too. I had never heard of the Green Giant by Greer Amps before and I kind of just stumbled upon the layout on Tagboard Effects and thought it sounded interesting. Other than what’s on […]

Transistor Saturation, Active, And Cutoff Region

August 23, 2024

It’s time to get a little more in depth on transistors. If you haven’t read it yet, check out my guide to transistors for some background on how transistors work in guitar pedals and in general. This article builds on the general guide to explain saturations, active, and cutoff region in transistors.  The basics of […]





Stripboard layout for an EarthQuaker Devices Acapulco Gold guitar pedal.

EarthQuaker Devices Acapulco Gold On Stripboard

August 18, 2024

https://youtu.be/ZgzqZcc0xWg The Acapulco Gold by EarthQuaker Devices is a pretty well know single knob distortion pedal. According to EarthQuaker Devices themselves, they’ve  modelled this pedal off of a Sunn Model T amplifier turned up to the max. Similar to the Lovelpedal Champ, the single knob on this pedal means the amount of drive is adjusted […]
