Introduction
Guitar effects pedals are essential tools for shaping and enhancing a guitarist’s tone. Two popular types of pedals that can dramatically alter your sound are distortion pedals and boost pedals. While they may seem similar on the surface, these pedals serve different purposes and produce distinct effects. This article will provide an in-depth comparison of distortion pedals and boost pedals to help guitarists understand their unique characteristics and applications.
Basic Definitions
Distortion Pedals
Distortion pedals are designed to alter the waveform of your guitar signal, creating a more aggressive, gritty, and harmonically rich tone. They achieve this by clipping the signal, which adds harmonic content and compression. Distortion pedals are commonly used in rock, metal, and other heavy genres to produce thick, saturated tones.
Boost Pedals
Boost pedals, on the other hand, are designed to increase the amplitude of your guitar signal without significantly altering its character. They provide a clean volume boost that can be used to drive the input stage of an amplifier harder, add more presence to your tone, or simply increase your volume for solos.
Signal Processing
How Distortion Pedals Process the Signal
Distortion pedals use various circuit designs to clip the guitar signal. This clipping can be achieved through diodes, op-amps, or transistors. The pedal amplifies the input signal and then clips it, creating harmonics and compressing the dynamic range. This process results in a more sustained, harmonically complex tone with reduced dynamic range.
Most distortion pedals offer controls for distortion amount, tone, and output level. Some advanced models may include additional EQ controls, multiple clipping modes, or even built-in noise gates.
How Boost Pedals Process the Signal
Boost pedals typically use a much simpler circuit design. They amplify the input signal without intentionally clipping it. The goal is to increase the signal’s amplitude while maintaining its original character as much as possible.
Basic boost pedals may have just a single knob controlling the amount of boost. More advanced models might include EQ controls or different voicings to shape the boosted signal subtly.
Tonal Characteristics
Distortion Pedal Tones
Distortion pedals can produce a wide range of tones, from mild crunch to extreme high-gain distortion. The exact character of the distortion depends on the pedal’s design and settings. Some common tonal characteristics include:
1. Increased sustain
2. Compressed dynamic range
3. Added harmonic content
4. Reduced note definition (especially at higher gain settings)
5. Thicker, more aggressive tone
6. Potential loss of low-end clarity
Distortion pedals can vary significantly in their tonal character. Some aim for a more “transparent” distortion that maintains the character of your guitar and amp, while others impart a strong coloration to your tone.
Boost Pedal Tones
Boost pedals, when used alone, aim to preserve the original tone of your guitar and amp while increasing volume. However, they can still affect your tone in subtle ways:
1. Increased volume without added distortion
2. Potential for slight mid-range boost (depending on the pedal design)
3. Possible high-end roll-off (especially with some vintage-style boost pedals)
4. Maintained note definition and dynamic range
5. Potential for increased touch sensitivity when driving a tube amp
Some boost pedals are designed to be as transparent as possible, while others may add a slight coloration or EQ curve to your tone.
Versatility and Applications
Distortion Pedal Applications
Distortion pedals are incredibly versatile and can be used in various musical contexts:
1. Creating heavy rhythm tones for rock and metal
2. Producing sustained lead tones for solos
3. Adding grit and aggression to clean or slightly overdriven amp tones
4. Stacking with other overdrive or distortion pedals for more extreme sounds
5. Creating wall-of-sound effects for shoegaze or noise rock
Distortion pedals are often used as an always-on effect to define a guitarist’s core tone, especially in heavier genres.
Boost Pedal Applications
While seemingly simpler, boost pedals offer a range of applications:
1. Increasing volume for solos without changing tone
2. Driving the input stage of a tube amp for natural overdrive
3. Compensating for volume loss when using long cable runs or effects chains
4. Pushing other pedals harder for more gain or altered tones
5. Adding more presence and cut to your tone in a mix
Boost pedals are often used situationally, engaged only when needed for solos or to push an amp into overdrive.
Impact on Dynamics and Playing Feel
Distortion Pedals and Dynamics
Distortion pedals generally compress your signal, which can significantly affect your playing dynamics:
1. Reduced dynamic range between soft and hard picking
2. Increased sustain, allowing notes to ring out longer
3. Potential loss of nuance in your picking technique
4. Easier to achieve consistent volume for fast passages
5. Can mask minor imperfections in technique
The amount of compression and its effect on dynamics can vary greatly between different distortion pedals and settings.
Boost Pedals and Dynamics
Boost pedals typically have less impact on your playing dynamics:
1. Maintained dynamic range between soft and hard picking
2. Preserved nuances in your picking technique
3. Potential for increased touch sensitivity when driving a tube amp
4. No added sustain (unless driving an amp into compression)
5. Exposes both the strengths and weaknesses of your technique
Boost pedals allow for more dynamic expression, which can be beneficial for styles that rely on subtle variations in touch and attack.
Interaction with Amplifiers
Distortion Pedals and Amplifiers
The interaction between distortion pedals and amplifiers can greatly affect your overall tone:
1. Can be used effectively with both clean and overdriven amp channels
2. May overpower the amp’s natural character, especially at high gain settings
3. Can sound different through various amp types (e.g., tube vs. solid-state)
4. May require adjustment of amp EQ to balance the overall tone
5. Can be used to push an already overdriven amp for more saturation
Some guitarists prefer to use distortion pedals with cleaner amp settings to have more control over their distorted tone.
Boost Pedals and Amplifiers
Boost pedals interact with amplifiers in a more subtle but equally important way:
1. Can drive a tube amp’s preamp section into natural overdrive
2. Maintains the amp’s inherent character and feel
3. Effectiveness can vary depending on the amp’s headroom
4. May reveal previously unheard nuances in your amp’s tone
5. Can be used to compensate for volume drops when switching to lower output pickups
The interaction between a boost pedal and an amplifier is often a key part of a guitarist’s tone-crafting process.
Noise and Signal Quality
Noise Considerations with Distortion Pedals
Distortion pedals, by their nature, can introduce additional noise into your signal chain:
1. Increased background hiss, especially at high gain settings
2. Potential for unwanted feedback, particularly with high-output pickups
3. May amplify existing noise from single-coil pickups
4. Some pedals include built-in noise gates to mitigate these issues
5. Higher quality pedals may offer better noise performance
Managing noise can be a significant consideration when using high-gain distortion pedals.
Noise Considerations with Boost Pedals
Boost pedals generally introduce less noise than distortion pedals:
1. Minimal added hiss when used alone
2. Can amplify existing noise in your signal chain
3. May reveal previously unnoticed noise when driving an amp harder
4. Generally maintain better signal clarity compared to distortion pedals
5. High-quality boost pedals can be nearly transparent in terms of added noise
While boost pedals add less noise themselves, they can make any existing noise in your rig more apparent.
Pedalboard Integration
Integrating Distortion Pedals
Distortion pedals can be versatile but sometimes challenging to integrate into a pedalboard:
1. Often placed early in the signal chain, before modulation effects
2. Can be stacked with other gain pedals for more tonal options
3. May require careful gain staging with other pedals to avoid excessive noise
4. Some guitarists use multiple distortion pedals for different sounds
5. Can interact unpredictably with some modulation and time-based effects
Experimentation is key to finding the right place for a distortion pedal in your signal chain.
Integrating Boost Pedals
Boost pedals are generally easier to integrate into a pedalboard:
1. Can be placed at various points in the signal chain for different effects
2. Often used at the end of the chain to boost overall volume
3. Can be placed before other gain pedals to push them harder
4. Generally play well with other effects without unwanted interactions
5. Some guitarists use multiple boost pedals for different purposes (e.g., clean boost and colored boost)
The versatility of boost pedals makes them a valuable tool in complex pedalboards.
Price and Quality Considerations
Distortion Pedal Pricing
Distortion pedals are available at a wide range of price points:
1. Budget options starting around $30-$50
2. Mid-range pedals typically between $100-$200
3. High-end boutique options can exceed $300
4. More expensive pedals often offer better components and more features
5. Some affordable pedals have achieved classic status (e.g., Boss DS-1)
The law of diminishing returns applies; beyond a certain point, increased cost may not yield proportional improvements in tone.
Boost Pedal Pricing
Boost pedals also vary widely in price:
1. Simple boost pedals can be found for as little as $40-$60
2. Mid-range options typically cost between $100-$150
3. High-end or feature-rich boost pedals can cost $200 or more

Conclusion
Both distortion pedals and boost pedals are valuable tools in a guitarist’s arsenal, each serving distinct purposes. Distortion pedals offer a wide range of tonal possibilities, from subtle grit to extreme high-gain sounds, making them ideal for shaping your core tone. They compress your signal, add harmonic content, and can dramatically alter your sound, but may also introduce noise and affect your playing dynamics.
Boost pedals, on the other hand, offer a more subtle effect, primarily increasing your signal level without significantly altering its character. They’re incredibly versatile, useful for driving amps, pushing other pedals, or simply increasing volume for solos. Boost pedals generally preserve your playing dynamics and introduce less noise, making them a valuable utility pedal for many guitarists.
Ultimately, the choice between a distortion pedal and a boost pedal depends on your specific needs, playing style, and the type of music you create. Many guitarists find both types of pedals indispensable, using them in different contexts or even together to craft their perfect tone. As with all aspects of guitar gear, experimentation is key to finding the combination that works best for you.
Frequently Asked Questions
Can I use a boost pedal to get distortion?
While a boost pedal isn’t designed to create distortion on its own, it can be used to push a tube amplifier into natural overdrive. By increasing the signal level going into the amp, you can cause the preamp tubes to saturate, resulting in a warm, organic distortion. This technique works best with tube amps that are already on the edge of breakup. With solid-state amps or very high-headroom tube amps, a boost pedal will typically just increase volume without adding distortion.
How do I choose between different types of distortion pedals?
Choosing a distortion pedal depends on several factors. Consider the genre of music you play, as different styles often favor certain types of distortion. Listen to demos and, if possible, try pedals in person to hear how they sound with your specific guitar and amp combination. Pay attention to the EQ controls and gain range to ensure the pedal can achieve the tones you want. Also, consider your budget and any additional features you might need, such as multiple channels or noise gates. Remember that personal preference plays a big role – what sounds great to one guitarist might not appeal to another.
Are there situations where I might need both a distortion pedal and a boost pedal?
Absolutely! Many guitarists use both distortion and boost pedals in their setups. A common approach is to use a distortion pedal for your primary overdriven or high-gain tone, and then use a boost pedal to push that sound further for solos or when you need to cut through the mix. Alternatively, you might use a boost pedal to drive your amp into natural overdrive for rhythm parts, and then kick on a distortion pedal for higher-gain lead tones. Some guitarists even use a boost pedal after their distortion pedal to increase overall volume without adding more distortion. The combination of these two pedal types can provide a wide range of tonal options and flexibility in your rig.
