What is a Sustain Pedal?

A sustain pedal allows you to lengthen the output signal of your guitar; in other words, it sustains the sound sent to the amp for a longer time. This can be used for on-stage live performances, but they are also used in studio recordings. 

Keep in mind that there is a considerable difference between delay pedals and sustain pedals – though many aspiring guitarists mix them up. The first one ‘delays’ the sound, in that the sound is played several times, one after the other, so it appears delayed, while the sustain pedal prolongs the sound sent to the amp. 

What Does a Sustain Pedal Do?

Long story short, the sustain pedal has four main levels: attack, decay, sustain, and release. These focus on how a sustain pedal actually works. Experimenting with different controls and timings will help you reach better quality sounds and performances, equalizing some sounds and finding your unique play style and genre. 

Remember that it is also relevant where you place it in the signal chain – we recommend towards the end because it handles the entire signal your guitar transmits. 

First Stage - Attack

First, the entire process begins with the attack phase. This is the moment where you play the sound, and it raises from zero decibels to maximum.

Second and Third Stage – Decay and Sustain

The next stage is when the sound falls down to the ‘sustain’ level (the one you adjust), followed by ‘sustain’ time – or the time wherein the sound remains at the sustain level. 

Release Stage

Lastly, the final stage is when you release the chord, and the sound finishes. This process is often known as ADSR and explains how a sustain pedal works through the four main segments described above. 

How to Choose a High-Quality Sustain Pedal

There is a wide variety of sustain pedals on the market, each of them with different price points, features, and characteristics. But which one is for you? Here’s a shortlist of must-have features when considering a sustain pedal:

Maintain a Natural Sound

First of all, the pedal should not interfere with the natural qualities of your instruments. Many low-budget options will result in a muddied original signal from the guitar, which is definitely a thing you should avoid! Keep an eye open for models that keep natural qualities intact – luckily, you can find them in the next section!

Little to No Interferences

Some sustain pedals can interfere with other equipment and make humming noises. Others have improved circuitry, which avoids such disaster, keeping your performance clean and crystal clear.  

Easy to Read and Use

Why buy a pedal you can’t use? If you’re a stage performer, make sure it is easy to read in the dark; otherwise, you will find it very difficult to manipulate it. Additionally, too many features, knobs, and controls can be extremely confusing if you are just starting with your effect pedals, so we recommend keeping it simple.

Advantages and Disadvantages of Sustain Pedals

Still in doubt whether to check it out or not? Check this section for a short breakdown of the main pros and cons of owning a sustain pedal. 


Here are the main advantages of sustain pedals:


You can level out the sounds of your instrument, sweeten the sound, and add some presence to your performance. These devices are extremely useful for live performance because they punch through clear rhythms. They can smooth and sweeten sounds, especially when paired with other effects, such as reverb. Sustain pedals are increasingly being used in modern tunes. 

Boost Volume

Some models can be used as volume boosters; additionally, they are great assets if you play in venues/places where you cannot play extremely loud; the compression will make it up for it.

Warmth and Tone

Depending on the music genre you play, a compressor might be a must-have accessory to recreate some popular tunes. These pedals add a little extra to the tone, which otherwise would make the sound incomplete. 


The main disadvantages include:


They can add unwanted noise if the product is of poor quality. So when purchasing a sustain pedal, make sure that you get the best pedal for your budget.


You can have a crammed pedalboard if you already own a lot of pedals, which means you will either need to get rid of a pedal or keep the sustain pedal separately.
