We’ll explore resistors, capacitors, transistors, integrated circuits (ICs), diodes, potentiometers, and enclosures, offering insights into their roles and the most frequently used types.
Understanding the Core Components of Guitar Pedals
Guitar pedals, at their heart, are electronic circuits designed to modify the audio signal of your guitar. While the specific components and their configurations vary wildly depending on the desired effect, certain parts appear consistently across a vast range of pedal designs. This analysis, compiled from examining the build documents of numerous Pedal PCB projects, sheds light on these essential guitar pedal parts. This data-driven approach helps builders prioritize which components to stock up on and provides a practical understanding of circuit design trends in the DIY pedal community.
Note: This guide is based on data from Q1 2021. Component availability and trends may have shifted since then, but the fundamental principles remain highly relevant.
Resistors: The Unsung Heroes of Pedal Circuits
Resistors are fundamental guitar pedal parts, acting as current regulators and voltage dividers within circuits. They are essential for setting gain levels, biasing transistors, and shaping the frequency response of effects. For a deeper dive into their function, explore our beginner’s guide to resistors for DIY guitar effects pedals.
Our analysis reveals that the 10K Ohm resistor is the most ubiquitous value in DIY guitar pedals. Across 457 pedal PCBs, we counted 1,546 instances of 10K resistors. This single value appears almost twice as often as the second most common, 4.7K Ohm resistors, which were used 823 times. Stocking up on 10K and 4.7K resistors is a smart move for any aspiring pedal builder.

Potentiometers: Variable Control for Guitar Effects
Bulk Potentiometers for guitar pedals
Potentiometers, or “pots,” are user-interactive guitar pedal parts that allow for variable resistance adjustment. They are crucial for controlling parameters like volume, gain, tone, and modulation rate without needing to modify the internal circuit directly. Pedals can range from having a single potentiometer to six or more, depending on their complexity.
The B100K potentiometer is the most common value, appearing 358 times in our analysis. The “B” indicates a linear taper, meaning the resistance changes uniformly as the knob is rotated. B100K pots are frequently used in tone stacks for controlling bass, mid, and treble frequencies.
The A100K potentiometer is the second most common, with 264 instances. “A” denotes a logarithmic or audio taper, where the resistance change is more pronounced in the initial part of the rotation. Logarithmic potentiometers are often preferred for volume controls as they more closely match human hearing perception.
The top 25 most common potentiometer values for DIY guitar pedals are:

Trimmers & Trim Pots: Fine-Tuning Your Pedal’s Sound
Trimmers, also known as trim pots, are small, adjustable guitar pedal parts typically mounted internally. They allow for fine-tuning circuit parameters, often used for transistor biasing or subtle tonal adjustments not intended for frequent user interaction.
The 100K Ohm trimmer is the most common value, appearing 62 times in our analysis. These are often used for transistor biasing to ensure optimal component performance within the circuit.
10K Ohm trimmers are the second most common, used 30 times, also frequently for transistor biasing.
The different trimmer values found in our analysis are:
| Rank | Trimmer Value | Count |
|---|---|---|
| 1 | 100K | 62 |
| 2 | 10K | 30 |
| 3 | 50K | 29 |
| 4 | 1K | 22 |
| 5 | 5K | 15 |
| 6 | 500R | 5 |
| 7 | 150K | 4 |
| 8 | 500K | 4 |
| 9 | 1M | 3 |
| 10 | 2K | 2 |
| 11 | 25K | 1 |
While not as frequently used as external potentiometers, trimmers are valuable for optimizing pedal performance and dialing in specific sonic characteristics.
Where to Buy Trimmers for Pedal Circuits
Trimmers are readily available in various styles, all serving the same function. Amazon and other suppliers offer these components in bulk:

Enclosures: Protecting Your Pedal Circuit
Bulk Enclosures for guitar pedals
Enclosures are essential guitar pedal parts, providing physical protection for the delicate circuitry inside and a robust housing for stomping on the footswitch. While builders can choose unique enclosures, a few standard sizes dominate the DIY pedal scene. Metal enclosures are generally preferred for grounding and durability.
The 125B enclosure is by far the most popular choice, used in 408 (89%) of the pedals we analyzed. Slightly larger than the 1590B, the 125B offers more internal space and is well-suited for pedals with top-mounted jacks, a popular space-saving trend on modern pedalboards.
The 1590BB enclosure is the second most common, used 27 times. Twice the width of the 125B, the 1590BB is ideal for dual-pedals or pedals requiring extra footswitches or controls.
The enclosure styles we found in our analysis are:
| Rank | Enclosure Style | Count |
|---|---|---|
| 1 | 125B | 408 |
| 2 | 1590BB | 27 |
| 3 | 1590XX | 16 |
| 4 | Wah | 6 |
Choosing the right enclosure size depends on the complexity of your circuit, the desired layout, and pedalboard space considerations.
Where to Purchase Enclosures for DIY Pedals
Standard pedal enclosures like the 125B and 1590BB are readily available. Wah enclosures are more specialized and expensive. Amazon and other suppliers offer these enclosures:
| Rank | Enclosure Style | Amazon Links |
|---|---|---|

| 2 | 1590BB | Check Out These 1590BB Enclosures On Amazon |
| 3 | 1590XX | Check Out These 1590XX Enclosures On Amazon |
| 4 | Wah | Not Available on Amazon |
For wah enclosures, consider repurposing broken wah pedals found on sites like eBay.
