A compressor pedal affects the sound dynamics of the electric guitars. It enhances the sound of quieter notes and, conversely, makes the loud sounds quieter. The best compressor pedal is capable of creating a balanced sound and beefy tone.

The compression effect comes in handy when you need to emphasize the lead guitar tone on a clean channel (due to its ability to enhance each individual note of the chord). The compression pedals are widely used with electric and rhythm guitars. Also, they are used both at live performances and in recording studios. The compressor pedals are able to make even usual budget guitar sound more assertively and more sophisticated.

Despite the fact that the compression pedal may seem simple at first glance, it allows using such advanced techniques as chicken pickin’, sweep picking, hammer-on, pull-off, and tapping.

There are a lot of compressor pedals on the market, which makes it difficult to choose the appropriate one, particularly for beginners. Consequently, we offer you to take a look at our list of the best compressor pedals that can ease your choice.

Do You Need A Compressor Pedal?

If you have never been trying to use a compressor pedal, you may feel confused about whether you really need it or not. So let’s run through the most popular applications, specs, and the possibilities it can give.

So, how the compression pedal can be helpful? This device can greatly simplify the creation of artificial flageolets. Trills, tapping, legato are also easier to perform with the guitar compressor turned on since the sound becomes evener. Some guitarists also use a compressor with a clear sound in order to equalize the sound dynamics.

Even if the compressor pedal features a lot of parameters, changing each of them won’t lead to drastic changes. This way, the result of sound processing performed by a compressor pedal is soft and barely noticeable. For instance, you may use it to just make your guitar sound louder and more expressive.

The compressor pedal is almost indispensable for rhythm parts in funk and blues. It can clearly stand out the guitar part in the song. Plus, it can fit the sound in the normal volume, eliminate the signal failures, and make your part sound more distinctly. When it comes to rock music, the pedal allows getting more sustain without the need to use too much distortion.

In the case, if you are playing solo that is slow and variable, then most likely you will not need a compressor.

So, the compression pedal gives the opportunity to diversify your sound and discover new features of your instrument. Most of the music directions (especially popular modern music), except for classical and some jazz movements, are directly related to the usage of the compression effect. Therefore it’s useful for recording, mixing, songwriting, etc.

How to Choose The Compressor Pedal?

When choosing the best compressor pedal, you need to pay special attention to some factors. For example, if you need a pedal that provides increased convenience, you should look for a device with easy operation. Such a pedal usually has a small number of controls and is easy in operation.

One of the most essential considerations when choosing a compressor pedal is an interface. The devices with a knob that allows switching between different modes makes the pedal control simpler. The pedal with minimal tone coloration will help you maintain the authenticity of your sound. It’s also recommendable to choose the pedal that features a true bypass to ensure cleaner sound. Or, if you need to boost your signal, go for the unit with buffered output. There are also a lot of models that can offer to switch between both of these features.

If you consider the compression effect as one of the most important ones in your signal chain, check if the pedal can offer several kinds of compression.

The construction of the pedal is also important. A lightweight and compact unit is easier to store and transport. It also will fit in your pedalboard with ease. The pedal with an LED indicator also gives more advantages and convenience since it shows the battery level, indicates an on/off status, etc.

Parameter Controls

Before getting a compressor pedal, it’s necessary to be aware of the parameters it can offer. It’s also worth to note that the pedal with a minimal set of control knobs shouldn’t be considered as the worse one. There are a lot of superior models that have only two controls.

It determines the sound level where the compressor begins to apply to the signal. If the Threshold level is too high, the signal won’t be subjected to any processing. If, on the contrary, the Threshold level is too low, then the entire signal will be compressed.

It determines the intensity of signal attenuation. Simply put, it allows controlling how much volume is reduced above the Threshold.

It’s the time after which the compressor activates. A long attack time allows applying the compression without affecting fast, transient signals. A short attack time will let you catch the instant notes and skip medium-duration sounds but will attenuate the high recording frequencies.

It’s the time during which the signal becomes uncompressed. As usual, the longer the release time is, the more natural is the sound.

Make-Up Gain
It allows raising the final compression to the required level. It’s the amplification stage between the input and output signals which provides the required signal level for recording and mixing.

It determines the dynamic range of the signal.

It determines how the signal will be processed after it exceeds the Threshold. The Hard Knee ensures a quick transition from the unprocessed signal to the processed one. The Soft Knee implies a smoother transition.

Note that each parameter works differently on each unit. From pedal to pedal, it can be more or less effective, allow reaching a variety of different effects or perform only the basic function.

Types of Compression

There are five main types of compression:

It uses an opto-isolation, made of a light bulb or an LED and a photocell. The light source blinks brighter or dimmer, depending on the level of the input signal. The photocell reads various brightness indicators and changes the gain level in accordance with them. The optical compressors usually have natural sounding of the Attack and Release, but they are also quite slow. Consequently, the optical compressors are more frequently used with vocals, bass, and electric guitars.

It uses the microcircuits thanks to which you can adjust the Attack and Release very accurately. Usually, such type of compressors don’t give out natural sound and can damp high frequencies at high compression levels.

It’s based on the circuits with a tube or tubes. As usual, such compressors have a warm and creamy tone. However, they don’t allow adjusting the depth of the compression. They also have the smallest dynamic range in comparison with other compression types.

It uses the transistor as a control element and has faster the Attack mode and cleaner sound but rather a limited dynamic range. Therefore, the FET compressors often distort the sound at high signal levels.

It compresses the signal differently at different frequencies. In other words, the multi-band compressors allow compressing high or low frequencies in different ways. The signal divides by frequency with the help of several filters at the input. After, different compression is applied for each divided signal, and then everything is mixed back at the output.

Using a Compressor Pedal With Other Effects

It’s not always easy to determine the pedal’s location in the signal chain. However, it’s one of the most important issues since you won’t get satisfactory results from any pedal if it is not placed properly.

Being located at the beginning of a chain, the pedal will produce minimal noise. However, the effects located after the compressor pedal won’t be subjected to compression. Being placed at the end, it will control the volume of the signal after all the other effects. However, in this case, the compression pedal will make the noise produced by the other pedals more noticeable. Never put the compressor after an overdrive effect or into an open loop of effects on a combo amplifier or you risk getting an excessively noisy sound.

In fact, the pedal’s placement depends not only on your personal preferences, music genre, and role in the band. It also depends on what you are trying to get out of your pedal, so it’s better to experiment around with its placement and you will be able to change your tone drastically.
