A whammy bar, also known as a tremolo arm or vibrato arm, is a mechanical lever attached to the bridge of a guitar. It is used to change the pitch of the strings, creating a vibrato effect. This effect can add expression and depth to a guitarist’s playing, making it an important tool for many styles of music. In this article, we’ll take a closer look at how whammy bars work, the different types of whammy bars available, and how to use them in your playing.
The Physics Behind Whammy Bars
The basic idea behind a whammy bar is simple: it allows the player to change the tension on the strings, altering the pitch. When the bar is pressed down, it pulls the strings tighter, raising the pitch. When the bar is released, the tension on the strings is relaxed, lowering the pitch.
This effect is made possible by the design of the guitar’s bridge. The bridge is what holds the strings in place, transmitting their vibrations to the guitar’s body to produce sound. The bridge on a guitar equipped with a whammy bar is designed to pivot on two points, allowing it to move back and forth as the bar is used.
The pivot points are often located at the two corners of the bridge, with the bar attached to the middle. This allows the player to change the tension on the strings by applying pressure to the bar. When the bar is pressed down, it pulls the bridge forwards, tightening the strings. When the bar is released, the bridge returns to its original position, relaxing the tension on the strings.
Types of Whammy Bars
There are several different types of whammy bars, each with its own unique design and features. Some of the most common types include:
Fixed Arm
The simplest type of whammy bar is the fixed arm. As its name suggests, this type of bar is fixed in place and cannot be moved. It is simply used to apply pressure to the bridge, altering the tension on the strings.
Floating Arm
A floating arm is a type of whammy bar that can be moved up and down, allowing the player to change the tension on the strings. This type of bar is often used by players who want more control over their vibrato effect.
Locking Tremolo
A locking tremolo is a type of whammy bar that can be locked in place, preventing it from moving when not in use. This type of bar is often used by players who want the benefits of a whammy bar but need to maintain accurate tuning.
Using Whammy Bars in Your Playing
Whammy bars can be used to add expression and depth to a guitarist’s playing. They can be used to create a wide range of sounds, from subtle vibrato effects to wild, dive-bombing sounds.
To use a whammy bar, simply press down on the bar to tighten the strings and raise the pitch. Release the bar to relax the tension on the strings and lower the pitch. The amount of pressure applied to the bar will determine the amount of pitch change.
It’s important to remember that using a whammy bar can cause the guitar to go out of tune. To help maintain accurate tuning, many players use a locking tremolo or some other type of locking mechanism.

Is it difficult to use a whammy bar?
Using a whammy bar can take some practice, but it is not inherently difficult. With a little bit of practice and patience, you’ll be able to add this powerful tool to your arsenal and take your playing to the next level.
Do I need a special guitar to use a whammy bar?
Yes, you will need a guitar with a tremolo system in order to use a whammy bar. Most modern electric guitars are equipped with a tremolo system, but it is important to check before making a purchase.
How do I maintain my whammy bar?
Regular maintenance of your whammy bar is important to keep it functioning properly. Clean the bar regularly with a soft cloth, and make sure to tighten any screws or bolts that may have come loose over time.
What is the best way to practice using a whammy bar?
The best way to practice using a whammy bar is to start slowly and gradually increase the speed and complexity of your movements. Experiment with different techniques, and try incorporating the whammy bar into your existing playing.
Can I use a whammy bar with other effects pedals?
Yes, you can use a whammy bar with other effects pedals. Experiment with different combinations to find the sounds you like best. Just keep in mind that some effects may interact differently with a whammy bar, so it’s important to test before using live.
