When setting up your pedalboard, one of the most important decisions you’ll make is where to place your compressor in the pedal chain. This seemingly simple choice can have a significant impact on your sound. In this article, we’ll explore where to put the compressor in your pedal chain for the best results, and why the placement matters for achieving a great tone. We’ll also touch on how compressors work with other pedals, the advantages of different configurations, and how to make your pedal setup work best for your style.
What is a Compressor in a Pedal Chain?
A compressor is a type of machine used in music to control the dynamics of your sound. In simple terms, it reduces the volume of loud sounds and increases the volume of quieter sounds, creating a more balanced overall sound. Compressors are a key component in many pedalboards, especially for players who want to tighten up their tone or create a more consistent dynamic range.
In general machinery, the compressor’s job is to smooth out volume fluctuations by adjusting the signal as it comes through the circuit. This makes your playing sound more even, with less extreme highs and lows. For guitarists and bass players alike, understanding where to place the compressor in the pedal chain is essential to getting the right sound.
Why Compressor Placement Matters
The placement of your compressor in the pedal chain affects how it interacts with the other pedals. Depending on where you place the compressor, you can shape your tone in different ways. Some players like to put the compressor at the front of the chain for a smoother tone, while others may prefer it towards the end for a more controlled sound.
The placement is also important because it determines how the compressor reacts to your instrument’s signal. This can influence how other effects, like overdrive or delay, sound when combined with the compression. Understanding this interaction is crucial for creating a pedalboard that works with your playing style.
General Rules for Pedal Chain Setup
In general, there are a few rules to follow when setting up your pedal chain. These rules are flexible, but understanding them helps you know why certain pedals work better in specific positions.
Input to Output Flow: Pedals should follow the flow of your instrument’s signal, from the guitar or bass through to the amp.
Time-Based Effects Last: Reverb, delay, and modulation effects generally work best towards the end of the chain, after most other effects.
Dynamics Control First: Effects that shape the overall dynamics, like compressors, are often best placed near the start of the signal chain.
Overdrive/Distortion Next: After dynamics shaping, it’s common to place pedals like overdrive and distortion, which benefit from a clear, even input signal.
Now that we understand some basic principles, let’s dive into the specifics of where to put a compressor in your pedal chain.
Where to Place a Compressor: The Front of the Chain
Compressor First in the Chain
Many players prefer to put their compressor first in the pedal chain, right after the instrument. This placement helps ensure that the compressor is shaping the entire signal before any other effects. Here are the benefits of placing the compressor at the front:
Even Signal for All Pedals: Placing the compressor first gives all the subsequent pedals a uniform signal to work with. This can prevent distortion pedals from overloading, as the compressor smooths out your input before they process the sound.
Tightens Up the Tone: By compressing the signal before any other pedals, you can tighten up your tone, especially if you’re using high-gain pedals. This is particularly useful for genres like rock, metal, and country, where a consistent, punchy sound is crucial.
More Control Over Dynamics: With the compressor at the front, you have better control over how dynamic your playing is. You can use it to level out the loudness of your picking and provide a more controlled tone, which is ideal for fingerpicking or fast, intricate playing.
The Disadvantage of This Position
One potential downside of placing the compressor at the front of the chain is that it can sometimes make overdrive and distortion pedals sound smoother than you may want. This happens because the compressor reduces the dynamics of your signal, which can make distortion less aggressive. If you want more bite from your overdrive, you might prefer placing the compressor further down the chain.
Where to Place a Compressor: After Distortion and Overdrive
Compressor After Overdrive
Another common placement for the compressor is after distortion or overdrive pedals. This setup is typically used by players who want to compress the sound after the gain has been applied. Here are the advantages of this placement:
Smooth Out Distortion: If you have a heavy distortion or overdrive pedal, placing the compressor afterward can smooth out the harshness and make your tone more consistent. This can be useful for players who want a more polished or refined distortion sound.
Keeps Distortion Dynamic: By placing the compressor after distortion, you preserve the natural dynamics of the distortion. The distortion pedals will still give you a punchy, responsive sound, while the compressor will even out the louder and quieter notes.
Sustains Notes: If you like to hold notes or need more sustain, placing the compressor after distortion can extend the sustain without muddying up the tone. This is especially useful for solos or longer notes.
The Disadvantage of This Position
The downside of putting the compressor after distortion is that it can sometimes make the tone too squashed. If you’re looking for a more dynamic distortion tone, this setup may not be the best for you. Some players find that this placement can make their sound less “alive” or reactive, which is important for some playing styles.
Where to Place a Compressor: In the Effects Loop
Compressor in the Effects Loop
Some players prefer to place their compressor in the effects loop of their amplifier, rather than in the main pedal chain. The effects loop comes after the preamp stage, meaning it’s a good place to apply compression after the amp has shaped the tone. Here are the benefits of this approach:
Preserves Tone Clarity: By placing the compressor in the effects loop, you allow the preamp to handle the tone shaping without interference from the compressor. This can preserve the clarity and dynamics of the sound, especially with complex tones from high-gain amps.
Helps with Amp-Specific Dynamics: If you’re using an amp with a lot of natural gain, placing the compressor in the loop can help even out your dynamics without compromising the amp’s tone. This setup works well for players who want to retain the unique character of their amp while still getting the benefits of compression.
The Disadvantage of This Position
A potential drawback of placing the compressor in the effects loop is that it can sometimes be less responsive. Because the signal is coming from the power amp section, it may not interact as dynamically with your playing as it would in the main chain. This can make it harder to dial in the right compression settings for your playing style.
Other Considerations for Compressor Placement
Using Multiple Compressors
Some pedalboards incorporate multiple compressors to achieve different levels of compression at different stages of the signal chain. For example, you could use a light compressor at the front of the chain for subtle tone shaping and a stronger compressor after distortion for more sustain. Experimenting with multiple compressors can provide a unique sound that works well for certain genres or playing techniques.
Compressor Settings
Regardless of where you place your compressor in the chain, the settings are just as important. Compression should be set to complement your playing style and the other pedals you’re using. Here are a few settings to consider:
Threshold: Controls the level at which compression kicks in. A lower threshold results in more compression, while a higher threshold lets through more of the natural dynamics.
Ratio: Controls how much compression is applied once the threshold is exceeded. Higher ratios result in more compression.
Attack: Controls how quickly the compressor reacts to the signal. A faster attack time can result in a tighter sound, while a slower attack allows for more natural dynamics.
Release: Controls how quickly the compressor stops compressing after the signal falls below the threshold. Adjusting the release can help smooth out transitions between notes.
Conclusion
Choosing the right placement for your compressor in the pedal chain is crucial for achieving the tone and dynamics you want. Whether you place it at the front, after distortion, or in the effects loop depends on your playing style and the sound you’re after. Experimenting with different configurations will help you find the best position for your compressor, allowing you to create a balanced and polished tone that enhances your overall sound.
No matter where you decide to put it, understanding the role of the compressor in your pedal chain will help you make the most of this essential machine.
