A compressor is the pedal most guitarists buy last and then never turn off. It evens out the difference between loud and quiet notes, adds sustain to single lines and gives clean parts that polished, finished sound you hear on records. In this guide to the best compressor pedal choices, we cover eight reliable options, from the classic squash of the MXR Dyna Comp to studio-style blend compressors, plus clear settings, placement tips and what each knob actually does.
What a compressor pedal does for guitar
A compressor turns down the loudest parts of your signal and, once you raise the output, brings up the quieter parts. The result is a more even level, longer sustain and a smoother attack. On clean funk and country parts it adds snap and consistency; on arpeggios it keeps every note audible; on solos it adds sustain without extra gain.
The key controls are Sustain or Compression (how hard it squeezes), Attack (how much of the pick transient gets through before the compressor clamps down), Level (output volume) and, on many modern pedals, Blend. A blend knob mixes your dry signal with the compressed one, which is the guitar version of parallel compression and keeps your playing dynamics alive. If you want the theory behind it, our explainer on how to use a compressor covers ratio, threshold, attack and release in detail.
Our picks
MXR Dyna Comp
The MXR Dyna Comp is the sound of classic country chicken-picking and funk rhythm. With just Output and Sensitivity knobs, it delivers an obvious, percussive squash with long sustain. If space is tight, the MXR Dyna Comp Mini adds an attack switch in a smaller box.
Best for: country, funk and anyone who wants compression they can clearly hear.
- Pros: iconic sound, dead simple, tough build.
- Cons: no blend, and it can get noisy at high sensitivity.
BOSS CS-3 Compression Sustainer
The BOSS CS-3 adds Attack and Tone controls to the basic formula, so you can shape how much pick click comes through and brighten the slightly dulled top end that heavy compression causes. It is affordable and built like every other BOSS compact.
Best for: beginners who want flexible compression on a budget.
- Pros: four useful controls, rugged, great value.
- Cons: buffered bypass and a slightly colored tone that some players notice.
Keeley Compressor Plus
The Keeley Compressor Plus is one of the most recommended guitar compressors, with Sustain, Level, Blend and Tone controls plus a release switch tuned for single coils or humbuckers. The blend control keeps your picking peaks, so it sounds natural even when left on all night.
Best for: players who want an always-on compressor that does not kill dynamics.
- Pros: blend control, very quiet, works on bass and acoustic too.
- Cons: mid-range price; subtle enough that beginners may not hear it at first.
Wampler Ego Compressor V2
The Wampler Ego Compressor takes the Ross-style circuit and adds Blend, Tone and Attack controls. You can go from full country squash to open, studio-style parallel compression, and it is designed to keep your core tone uncolored.
Best for: players who want one compressor that covers subtle and extreme settings.
- Pros: five controls, wide range, transparent core tone.
- Cons: larger enclosure than the many mini compressors around.
Xotic SP Compressor
The Xotic SP Compressor packs Volume and Blend knobs onto a tiny pedal, with a three-way switch for low, mid and high compression and internal DIP switches for attack and EQ tweaks. It is a favourite for small, polished boards.
Best for: players who want blend compression in a mini format.
- Pros: tiny, quiet, flexible once you explore the internal switches.
- Cons: deeper settings are hidden inside the case.
Electro-Harmonix Tone Corset
The Electro-Harmonix Tone Corset is an analog compressor with Sustain, Attack, Blend and Volume controls and true bypass. It covers much of the same ground as boutique blend compressors for a lower outlay.
Best for: value seekers who still want a blend knob.
- Pros: four-knob control set, analog circuit, true bypass.
- Cons: no tone control, and it is a little larger than mini-format rivals.
TC Electronic HyperGravity Compressor
The TC Electronic HyperGravity is a multiband compressor in pedal form, treating lows, mids and highs separately for a studio-style result, with a Vintage mode for classic stomp squash. TonePrint support lets you load artist and custom presets.
Best for: players who want polished, studio-like compression and like to tweak.
- Pros: multiband processing, true or buffered bypass, TonePrint presets.
- Cons: digital, and the deepest editing needs the app.
Behringer CS400 (budget pick)
The Behringer CS400 follows the BOSS CS-3 layout with Level, Tone, Attack and Sustain controls in a plastic housing. It is a very cheap way to hear what compression adds to your playing.
Best for: curious beginners on a minimal budget.
- Pros: extremely low cost, four familiar controls.
- Cons: plastic build, and noisier than the others here.

How to choose the best compressor pedal
Audible effect or invisible polish? If you want the squashed, quacky sound of funk and country, a Dyna Comp or CS-3 delivers it. If you want compression you feel more than hear, pick a pedal with a blend knob, such as the Keeley, Wampler, Xotic or Tone Corset.
Noise. Compressors raise the quiet parts of your signal, including hum and hiss. Single-coil pickups and high sustain settings make this worse. Quieter designs and a good isolated power supply help.
Size and control count. Mini pedals save room but often hide controls inside. If you like to tweak on stage, choose visible attack and tone knobs.
Other instruments. Blend compressors generally work well on bass and acoustic-electric guitar. For bass-specific advice, see our guide on how to compress bass guitar.
Placement and starting settings
The most common spot is first in the chain after the tuner, so the compressor evens out your playing before any drive. Placing it after overdrive is also valid, but it will raise the noise of the drive pedals. Some players put a second, gentle compressor at the end of the chain for overall polish. Our guide to building a pedalboard shows the whole order.
- Country chicken-picking: sustain at 2 o’clock, attack fast, level matched to bypass, no blend.
- Funk rhythm: sustain around noon, attack slower so the pick snap comes through, tone slightly bright.
- Always-on polish: sustain at 10 o’clock, blend around 50 percent, level at unity.
- Clean solo sustain: sustain high, blend mostly wet, then lower your amp gain to control noise.
When you record guitar into a DAW, a pedal compressor shapes how you play, while a plugin shapes the finished track. Use both lightly rather than one heavily. For mixing, our roundup of the best compressor plugins covers software options.
FAQ
Do I need a compressor pedal as a beginner?
Not straight away. A tuner and a drive pedal usually come first. A compressor becomes useful once you play clean rhythm, funk, country or arpeggiated parts and want them more even and polished.
Can a compressor pedal go before overdrive?
Yes, and that is the most common setup. A compressor before overdrive gives a more even signal into the drive, adding sustain. After overdrive it boosts noise more but can smooth out volume jumps between drive sounds.
Why does my compressor pedal make my guitar noisy?
Because compression raises the quietest parts of your signal, including hum and hiss. Lower the sustain, use a blend control, switch to an isolated power supply and keep the guitar volume up to improve the signal-to-noise ratio.
