How to Choose the Right Guitar Knobs
Whether you're upgrading your guitar, restoring a vintage model, or customizing a new build, choosing the right guitar knobs can make a surprising difference in both functionality and aesthetics. In this guide, we'll walk you through everything you need to know about selecting the perfect guitar knobs for your instrument.
1. Know Your Potentiometer Shaft Type
Before choosing knobs, it's crucial to identify what type of potentiometer shaft your guitar has. This determines the compatibility of the knob and ensures a proper fit.
Common Potentiometer Shaft Types
- Split Shaft (Knurled): Features a split and usually 18 or 24 splines. Common in Fender-style guitars.
- Solid Shaft: Smooth cylindrical shaft, typically found in Gibson-style guitars.
- D-Shaped Shaft: One flat side for alignment. Found in some modern guitars and electronic instruments.
Tip: Always check the diameter — either 6mm (metric) or 6.35mm (1/4 inch, imperial) — to ensure compatibility with your new knobs.
2. Choose Your Installation Style
There are two main installation types for guitar knobs. Each has unique advantages depending on your hardware setup.
Push-on Knobs
Simply press onto a split shaft. No tools needed, quick and convenient for most modern guitars.
Set-screw Knobs
Secured with a small side screw, ideal for solid or D-shaft potentiometers. They offer a firmer, more secure fit — preferred by professional guitar techs.
Summary: Push-on knobs are easy to install, while set-screw types are more versatile and secure.
3. Select the Right Knob Style
Different guitar knob styles suit different instruments and playing preferences.
Common Knob Styles
- Dome Knobs: Metal knobs with a flat or rounded top. Often used on Telecasters.
- Top Hat Knobs: Tall, cylindrical knobs with a skirted bottom. Classic choice for Stratocasters.
- Bell Knobs: Shaped like a bell with numbered indicators. Common on Les Paul guitars.
- Speed Knobs: Similar to bell knobs but shorter and easier to turn quickly — great for fast volume swells.
- Chicken Head Knobs: Vintage-style pointer knobs often found on amps and some retro guitars.
4. Material and Finish
The material of your guitar knob affects both the appearance and tactile feel.
Popular Knob Materials
- Plastic: Lightweight and classic. Available in many colors and styles.
- Metal: Durable and sleek. Adds weight and a premium feel to your guitar.
- Wood: Unique and boutique-style. Perfect for custom or handmade instruments.
- Resin or Shell: Visually stunning, ideal for themed or decorative builds.
Choose a finish that complements your guitar body and hardware — such as chrome, gold, or black — to create a cohesive visual design.
5. Functionality Matters
When selecting guitar knobs, think about how you’ll actually use them.
- Need quick volume swells? Choose speed knobs for effortless control.
- Want precision adjustments? Go for knobs with indicator lines or numbered markers.
- Perform live on stage? Choose knobs with good grip and high visibility under lighting.
The right knob can improve your control and enhance your performance comfort.
6. Pro Tips for Selecting Guitar Knobs
- Measure before you buy: Always measure your potentiometer shaft and check the knob’s inner diameter.
- Unsure about compatibility? Choose set-screw knobs — they work with most pot types.
- Don’t forget the look: Matching knobs with your pickguard, tuners, and pickup covers creates a unified, professional aesthetic.
