In my early days teaching guitar, I was asked an unexpected and tough-to-answer question: How important are metal enclosures for guitar pedals?
As a guitar teacher with a small but growing pedal collection at the time, I felt obligated to provide an accurate and knowledgeable response.
But the truth is, I didn’t have one.
Since then, I’ve been on one hell of a journey. I’ve tried hundreds of pedals made of all kinds of different materials. I’ve listened to and studied countless experts on tone, and finally, I have a nuanced answer to this question.
Let me explain in this article as I explore the debate on the metal vs plastic pedal enclosure.
Key Takeaways
- All guitar pedal enclosures protect the pedal’s electronic components.
- Metal enclosures offer strength and electrical shielding but are heavier and costlier.
- Plastic enclosures are lighter and generally cheaper.

What Are Pedal Enclosures Made Of?
Pedal enclosures are usually made of aluminum, steel, or plastic, although there are some weird and wonderful alternative options out there.
For example, the Ruach Amp Juice Pedal is made from Cherry wood (2).
The pedal enclosure protects the circuit board and electronic components inside from the outside world’s rough and tumble. It can even protect against electromagnetic interference (more on this later).
All pedal enclosures, plastic or metal, are designed to be long-lasting and durable.
Many metal enclosures have a powder-coated finish resistant to scratches and corrosion, while plastic enclosures are made from high-quality materials to withstand regular usage.
Both types of enclosures come in many different shapes and sizes. But, the enclosure size usually depends on the number of components inside the pedal.
How Important Are Metal Enclosures for Guitar Pedals
Let’s clarify one thing: a metal enclosure doesn’t mean the pedal is better—many other factors come into play here.
However, metal enclosures are a popular choice for many guitarists, and they are associated with a certain level of quality.
Let’s look at what makes metal pedal enclosures so appealing.
The Benefits of Metal Effects Pedal Enclosures
One question many people ask when faced with the choice between metal and plastic pedals is whether there are any benefits to paying extra for a metal enclosure.
Short answer: Yes! And here are some reasons why.
1. They’re strong and long-lasting
Metal enclosures are the standard for high-quality pedals. For touring musicians, a metal enclosure should protect against almost anything they encounter on the road.
2. Enhanced electrical shielding
Guitar effects pedals can often suffer from electromagnetic interference (EMI). This is disruption caused by other electronic devices such as phones, computers, and microwaves. EMI can interfere with your guitar signal, causing unwanted noise.
I believe one of the biggest benefits of metal enclosures is that they can shield your signal from this EMI.
Have you ever heard of a Faraday Cage?
Well, a Faraday cage is an enclosure made of conductive materials that blocks external static and non-static electric fields by channeling electricity along and around, but not through, the enclosure (1).
Metal enclosures can function as Faraday cages for your guitar signal in a way that plastic pedals can’t. This shielding helps the signal inside the pedal, ensuring that the sound produced by your guitar is noise-free and exactly as intended.
So, if you’re looking for good protection against interference in your guitar’s sound, metal pedal enclosures are typically better than plastic ones.
3. Metal pedal enclosures don’t get as hot
Another reason to consider metal pedal enclosures is their ability to dissipate heat effectively.
This is important for all electronic devices, as it plays a major role in the longevity of the electrical components.
The electronic circuits within the pedal generate heat as they operate. If this heat accumulates, it can lead to overheating, which may harm the pedal’s functionality and reduce the lifespan of its components.
In a metal enclosure, the heat generated by these electronic components is quickly absorbed by the casing. The metal then disperses this heat across its surface area and releases it into the surrounding environment. This process keeps the pedal’s internal temperature lower than in a plastic enclosure, which typically insulates heat rather than conducts it.
Okay. Okay. I know what you’re thinking: “Is this really a concern?”
In theory: Yes!
In reality, I’ve never had a plastic pedal overheat, so I wouldn’t let this be a deciding factor.
How Important Are Plastic Enclosures for Guitar Pedals
Plastic pedal enclosures are a practical choice for many guitarists. And there are some fantastic plastic-bodied pedals on the market today.
My first pedal was a plastic Zoom multi-effects pedal. I don’t remember the model, but that pedal provided me with years of enjoyment and was a huge part of my guitar journey so far.
Benefits of Plastic Pedal Enclosures
Plastic pedals are popular among beginners or those looking for a more cost-effective option, but many proficient touring musicians still opt for plastic over metal.
And here’s why:
1. They’re lightweight
Most musicians don’t have a team of roadies to help transport their gear. Lightweight gear is not only easier to carry, but it’s also cheaper to transport.
That’s why plastic enclosures can be an excellent choice for musicians who frequently travel with pedals.
But not only the touring musicians can benefit. Pedalboards with plastic-encased pedals are also easier for anyone who, for example, needs to take the bus or train to band practice.
2. They usually cost less
Plastic pedals are often cheaper than metal ones, which makes them a good option for guitarists on a budget.
The lower cost makes experimenting with a wider range of sounds and effects easier without spending a fortune.
3. They’re corrosion resistant
Unlike metal, plastic pedals will not corrode over time.
Now, I’m not saying metal pedal owners need to start worrying about their pedals rusting (they’re treated to protect against this).
But if you live in a humid or salty environment, this can be a real risk, and you might want to consider choosing plastic pedals for your pedalboard.
How To Decide Between Plastic and Metal Effects Pedals
You’ve seen the benefits of both plastic and metal pedal enclosures, but how do you decide which is for you?
Here’s how I look at it.
If you want to invest in a pedal that will be an integral part of your pedalboard for a long time, consider metal. It’s stronger and provides more effective EMI shielding.
If you’re on a budget, looking for a pedal to experiment with, or trying to build the lightest pedalboard possible, go for plastic.
All in all, though, the right pedal for you is the one that sounds awesome and feels great to play. If it inspires you to pick up and play your guitar, who cares what it’s made of?
FAQs
Here, we answer some common questions about metal and plastic pedal enclosures.
What can I use as a pedal enclosure?
If you’re building your own pedal or rehousing another, you can use various materials, such as aluminum, steel, or plastic, as a pedal enclosure. It’s important to choose a material that is sturdy, lightweight, and able to withstand regular use.
When selecting the pedal enclosure material, you might also want to consider factors like cost, aesthetics, and ease of customization. Plastic is often cheaper than metal. Whereas metal is easy to paint or customize.
What are pedal enclosures made of?
Pedal enclosures are typically made of metal or plastic.
Why are guitar pedals made of metal?
Not all guitar pedals are made of metal, but lots are made of metal for extra strength and protection against damage and everyday use. Metal guitar pedals might also offer more protection for your guitar’s signal against electromagnetic interference.
Why are metal guitar pedals better?
Metal guitar pedals are often considered better because they are usually stronger and longer lasting than plastic pedals.
